    Researchers at University of Rochester’s Institute of Optics for first time distill novel interferometry into a photonic device.

    By merging two or more sources of light, interferometers create interference patterns that can provide remarkably detailed information about everything they illuminate, from a tiny flaw on a mirror, to the dispersion of pollutants in the atmosphere, to gravitational patterns in far reaches of the Universe.

    “If you want to measure something with very high precision, you almost always use an optical interferometer, because light makes for a very precise ruler,” says Jaime Cardenas, assistant professor of optics at the University of Rochester.

    Now, the Cardenas Lab has created a way to make these optical workhorses even more useful and sensitive. Meiting Song, a PhD student, has for the first time packaged an experimental way of amplifying interferometric signals—without a corresponding increase in extraneous, unwanted input, or “noise”—on a 1 mm by 1 mm integrated photonic chip. The breakthrough, described in Nature Communications, is based on a theory of weak value amplification with waveguides that was developed by Andrew Jordan, a professor of physics at Rochester, and students in his lab.

    Jordan and his group have been studying weak value amplification for over a decade. They have applied mode analysis in a novel way on free space interferometer with weak value amplification, which bridged the gap between free space and waveguide weak value amplification. Therefore, they were able to prove the theoretical feasibility of integrating weak value amplification on a photonic chip.

    “Basically, you can think of the weak value amplification technique as giving you amplification for free. It’s not exactly free since you sacrifice power, but it’s almost for free, because you can amplify the signal without adding noise—which is a very big deal,” Cardenas says.

    Weak value amplification is based on the quantum mechanics of light, and basically involves directing only certain photons that contain the information needed, to a detector. The concept has been demonstrated before, “but it’s always with a large setup in a lab with a table, a bunch of mirrors and laser systems, all very painstakingly and carefully aligned,” Cardenas says.

    “Meiting distilled all of this and put it into a photonic chip,” Cardenas says. “And by having the interferometer on a chip, you can put it on a rocket, or a helicopter, in your phone—wherever you want—and it will never be misaligned.”

    The device Song created does not look like a traditional interferometer. Instead of using a set of tilted mirrors to bend light and create an interference pattern, Song’s device includes a waveguide engineered to propagate the wavefront of an optical field through the chip.

    “This is one of the novelties of the paper,” Cardenas says. “No one has really talked about wavefront engineering on a photonic chip.”

Song “distilled all of this and put it into a photonic chip.” The chip requires only a single microscope (right). Credit: J. Adam Fenster/University of Rochester.

    With traditional interferometers, the signal to noise ratio can be increased, resulting in more meaningful input, by simply cranking up the laser power. But there’s actually a limitation, Cardenas says, because the traditional detectors used with interferometers can handle only so much laser power before becoming saturated, at which point the signal to noise ratio can’t be increased.

    Song’s device removes that limitation by reaching the same interferometer signal with less light at the detectors, which leaves room to increase the signal to noise ratio by continuing to add laser power.

    Bottom line: “If the same amount of power reaches the detector in Meiting’s weak value device as in a traditional interferometer, Meiting’s device will always have a better signal to noise ratio,” Cardenas says. “This work is really cool, really subtle, with a lot of very nice physics and engineering going on in the background.”

    Next steps will include adapting the device for coherent communications and quantum applications using squeezed or entangled photons to enable devices such as quantum gyroscopes.

    History

    Early history

    The University of Rochester traces its origins to The First Baptist Church of Hamilton (New York) which was founded in 1796. The church established the Baptist Education Society of the State of New York later renamed the Hamilton Literary and Theological Institution in 1817. This institution gave birth to both Colgate University(US) and the University of Rochester. Its function was to train clergy in the Baptist tradition. When it aspired to grant higher degrees it created a collegiate division separate from the theological division.

    The collegiate division was granted a charter by the State of New York in 1846 after which its name was changed to Madison University. John Wilder and the Baptist Education Society urged that the new university be moved to Rochester, New York. However, legal action prevented the move. In response, dissenting faculty, students, and trustees defected and departed for Rochester, where they sought a new charter for a new university.

    Madison University was eventually renamed as Colgate University (US).

    Founding

    Asahel C. Kendrick- professor of Greek- was among the faculty that departed Madison University for Rochester. Kendrick served as acting president while a national search was conducted. He reprised this role until 1853 when Martin Brewer Anderson of the Newton Theological Seminary in Massachusetts was selected to fill the inaugural posting.

    The University of Rochester’s new charter was awarded by the Regents of the State of New York on January 31, 1850. The charter stipulated that the university have $100,000 in endowment within five years upon which the charter would be reaffirmed. An initial gift of $10,000 was pledged by John Wilder which helped catalyze significant gifts from individuals and institutions.

    Classes began that November with approximately 60 students enrolled including 28 transfers from Madison. From 1850 to 1862 the university was housed in the old United States Hotel in downtown Rochester on Buffalo Street near Elizabeth Street- today West Main Street near the I-490 overpass. On a February 1851 visit Ralph Waldo Emerson said of the university:

    “They had bought a hotel, once a railroad terminus depot, for $8,500, turned the dining room into a chapel by putting up a pulpit on one side, made the barroom into a Pythologian Society’s Hall, & the chambers into Recitation rooms, Libraries, & professors’ apartments, all for $700 a year. They had brought an omnibus load of professors down from Madison bag and baggage… called in a painter and sent him up the ladder to paint the title “University of Rochester” on the wall, and they had runners on the road to catch students. And they are confident of graduating a class of ten by the time green peas are ripe.”

    For the next 10 years the college expanded its scope and secured its future through an expanding endowment; student body; and faculty. In parallel a gift of 8 acres of farmland from local businessman and Congressman Azariah Boody secured the first campus of the university upon which Anderson Hall was constructed and dedicated in 1862. Over the next sixty years this Prince Street Campus grew by a further 17 acres and was developed to include fraternities houses; dormitories; and academic buildings including Anderson Hall; Sibley Library; Eastman and Carnegie Laboratories the Memorial Art Gallery and Cutler Union.

    Twentieth century

    Coeducation

    The first female students were admitted in 1900- the result of an effort led by Susan B. Anthony and Helen Barrett Montgomery. During the 1890s a number of women took classes and labs at the university as “visitors” but were not officially enrolled nor were their records included in the college register. President David Jayne Hill allowed the first woman- Helen E. Wilkinson- to enroll as a normal student although she was not allowed to matriculate or to pursue a degree. Thirty-three women enrolled among the first class in 1900 and Ella S. Wilcoxen was the first to receive a degree in 1901. The first female member of the faculty was Elizabeth Denio who retired as Professor Emeritus in 1917. Male students moved to River Campus upon its completion in 1930 while the female students remained on the Prince Street campus until 1955.

    Expansion

    Major growth occurred under the leadership of Benjamin Rush Rhees over his 1900-1935 tenure. During this period George Eastman became a major donor giving more than $50 million to the university during his life. Under the patronage of Eastman the Eastman School of Music (US) was created in 1921. In 1925 at the behest of the General Education Board and with significant support for John D. Rockefeller George Eastman and Henry A. Strong’s family medical and dental schools were created. The university award its first Ph.D that same year.

    During World War II University of Rochester was one of 131 colleges and universities nationally that took part in the V-12 Navy College Training Program which offered students a path to a Navy commission. In 1942, the university was invited to join the Association of American Universities(US) as an affiliate member and it was made a full member by 1944. Between 1946 and 1947 in infamous uranium experiments researchers at the university injected uranium-234 and uranium-235 into six people to study how much uranium their kidneys could tolerate before becoming damaged.

    In 1955 the separate colleges for men and women were merged into The College on the River Campus. In 1958 three new schools were created in engineering; business administration and education. The Graduate School of Management was named after William E. Simon- former Secretary of the Treasury in 1986. He committed significant funds to the school because of his belief in the school’s free market philosophy and grounding in economic analysis.

    Financial decline and name change controversy

    Following the princely gifts given throughout his life George Eastman left the entirety of his estate to the university after his death by suicide. The total of these gifts surpassed $100 million before inflation and as such Rochester enjoyed a privileged position amongst the most well endowed universities. During the expansion years between 1936 and 1976 the University of Rochester’s financial position ranked third, near Harvard University’s(US) endowment and the University of Texas (US) System’s Permanent University Fund. Due to a decline in the value of large investments and a lack of portfolio diversity the university’s place dropped to the top 25 by the end of the 1980s. At the same time the preeminence of the city of Rochester’s major employers began to decline.

    In response the University commissioned a study to determine if the name of the institution should be changed to “Eastman University” or “Eastman Rochester University”. The study concluded a name change could be beneficial because the use of a place name in the title led respondents to incorrectly believe it was a public university, and because the name “Rochester” connoted a “cold and distant outpost.” Reports of the latter conclusion led to controversy and criticism in the Rochester community. Ultimately, the name “University of Rochester” was retained.

    Renaissance Plan

    In 1995 University of Rochester president Thomas H. Jackson announced the launch of a “Renaissance Plan” for The College that reduced enrollment from 4,500 to 3,600 creating a more selective admissions process. The plan also revised the undergraduate curriculum significantly creating the current system with only one required course and only a few distribution requirements known as clusters. Part of this plan called for the end of graduate doctoral studies in chemical engineering; comparative literature; linguistics; and mathematics the last of which was met by national outcry. The plan was largely scrapped and mathematics exists as a graduate course of study to this day.

    Twenty-first century

    Meliora Challenge

    Shortly after taking office university president Joel Seligman commenced the private phase of the “Meliora Challenge”- a $1.2 billion capital campaign- in 2005. The campaign reached its goal in 2015- a year before the campaign was slated to conclude. In 2016, the university announced the Meliora Challenge had exceeded its goal and surpassed $1.36 billion. These funds were allocated to support over 100 new endowed faculty positions and nearly 400 new scholarships.

    The Mangelsdorf Years

    On December 17, 2018 the University of Rochester announced that Sarah C. Mangelsdorf would succeed Richard Feldman as President of the University. Her term started in July 2019 with a formal inauguration following in October during Meliora Weekend. Mangelsdorf is the first woman to serve as President of the University and the first person with a degree in psychology to be appointed to Rochester’s highest office.

    In 2019 students from China mobilized by the Chinese Students and Scholars Association (CSSA) defaced murals in the University’s access tunnels which had expressed support for the 2019 Hong Kong Protests, condemned the oppression of the Uighurs, and advocated for Taiwanese independence. The act was widely seen as a continuation of overseas censorship of Chinese issues. In response a large group of students recreated the original murals. There have also been calls for Chinese government run CSSA to be banned from campus.

    Research

    Rochester is a member of the Association of American Universities (US) and is classified among “R1: Doctoral Universities – Very High Research Activity”.

    Rochester had a research expenditure of $370 million in 2018.

    In 2008 Rochester ranked 44th nationally in research spending but this ranking has declined gradually to 68 in 2018.

    Some of the major research centers include the Laboratory for Laser Energetics, a laser-based nuclear fusion facility, and the extensive research facilities at the University of Rochester Medical Center.

    Recently the university has also engaged in a series of new initiatives to expand its programs in biomedical engineering and optics including the construction of the new $37 million Robert B. Goergen Hall for Biomedical Engineering and Optics on the River Campus.

    Other new research initiatives include a cancer stem cell program and a Clinical and Translational Sciences Institute. UR also has the ninth highest technology revenue among U.S. higher education institutions with $46 million being paid for commercial rights to university technology and research in 2009. Notable patents include Zoloft and Gardasil. WeBWorK, a web-based system for checking homework and providing immediate feedback for students was developed by University of Rochester professors Gage and Pizer. The system is now in use at over 800 universities and colleges as well as several secondary and primary schools. Rochester scientists work in diverse areas. For example, physicists developed a technique for etching metal surfaces such as platinum; titanium; and brass with powerful lasers enabling self-cleaning surfaces that repel water droplets and will not rust if tilted at a 4 degree angle; and medical researchers are exploring how brains rid themselves of toxic waste during sleep.

    From The University of Rochester (US): “Rochester researchers set ‘ultrabroadband’ record with entangled photons”

    Researchers in the lab of Qiang Lin at the University of Rochester have generated record ‘ultrabroadband’ bandwidth of entangled photons using the thin-film nanophotonic device illustrated here. At top left, a laser beam enters a periodically poled thin-film lithium niobate waveguide (banded green and gray). Entangled photons (purple and red dots) are generated with a bandwidth exceeding 800 nanometers. Illustration by Usman Javi and Michael Osadciw.

    The engineers have achieved unprecedented bandwidth and brightness on chip-sized nanophotonic devices.

    Quantum entanglement—or what Albert Einstein once referred to as “spooky action at a distance”— occurs when two quantum particles are connected to each other, even when millions of miles apart. Any observation of one particle affects the other as if they were communicating with each other. When this entanglement involves photons, interesting possibilities emerge, including entangling the photons’ frequencies, the bandwidth of which can be controlled.

    Researchers at the University of Rochester have taken advantage of this phenomenon to generate an incredibly large bandwidth by using a thin-film nanophotonic device they describe in Physical Review Letters.

    The breakthrough could lead to:

    -Enhanced sensitivity and resolution for experiments in metrology and sensing, including spectroscopy, nonlinear microscopy, and quantum optical coherence tomography.
    -Higher dimensional encoding of information in quantum networks for information processing and communications.

    “This work represents a major leap forward in producing ultrabroadband quantum entanglement on a nanophotonic chip,” says Qiang Lin, professor of electrical and computer engineering. “And it demonstrates the power of nanotechnology for developing future quantum devices for communication, computing, and sensing.”

    No more tradeoff between bandwidth and brightness

    To date, most devices used to generate broadband entanglement of light have resorted to dividing up a bulk crystal into small sections, each with slightly varying optical properties and each generating different frequencies of the photon pairs. The frequencies are then added together to give a larger bandwidth.

    “This is quite inefficient and comes at a cost of reduced brightness and purity of the photons,” says lead author Usman Javid, a PhD student in Lin’s lab. In those devices, “there will always be a tradeoff between the bandwidth and the brightness of the generated photon pairs, and one has to make a choice between the two. We have completely circumvented this tradeoff with our dispersion engineering technique to get both: a record-high bandwidth at a record-high brightness.”

    The thin-film lithium niobate nanophotonic device created by Lin’s lab uses a single waveguide with electrodes on both sides. Whereas a bulk device can be millimeters across, the thin-film device has a thickness of 600 nanometers—more than a million times smaller in its cross-sectional area than a bulk crystal, according to Javid. This makes the propagation of light extremely sensitive to the dimensions of the waveguide.

    Indeed, even a variation of a few nanometers can cause significant changes to the phase and group velocity of the light propagating through it. As a result, the researchers’ thin-film device allows precise control over the bandwidth in which the pair-generation process is momentum-matched. “We can then solve a parameter optimization problem to find the geometry that maximizes this bandwidth,” Javid says.

    The device is ready to be deployed in experiments but only in a lab setting, Javid says. In order to be used commercially a more efficient and cost-effective fabrication process is needed. And although lithium niobate is an important material for light-based technologies, lithium niobate fabrication is “still in its infancy, and it will take some time to mature enough to make financial sense,” he says.

    Other collaborators include coauthors Jingwei Ling, Mingxiao Li, and Yang He of the Department of Electrical and Computer Engineering, and Jeremy Staffa of the Institute of Optics, all of whom are graduate students. Yang He is a postdoctoral researcher.

    From The University of Rochester (US): “A big leap forward in using iron catalysts for pharmaceuticals”

    Researchers at Rochester and The University of Maryland (US) describe a novel cross-coupling reaction.

    If there were a classroom full of all the transition metals that could be used as catalysts for complex pharmaceutical reactions, iron would be the most promising but most unruly member.

    However, researchers at the University of Rochester and the University of Maryland have created and characterized a new kind of reaction that could potentially bring iron to the front of the class, enabling faster, less expensive synthesis of previously difficult to make, drug-like compounds in a single step. They report their findings in the journal Science.

    “This is a tremendous leap forward in developing effective and practical iron-based reactions that the pharmaceutical industry could utilize,” says Michael Neidig, the Marshall D. Gates, Jr. Professor of Chemistry at Rochester, whose research group collaborated with that of associate professor of chemistry Osvaldo Gutierrez at Maryland, before Gutierrez moved to The Texas A&M University (US) in August 2021.

    Iron: a better catalyst than palladium for chemical synthesis.

    So-called transition-metal catalyzed cross-coupling reactions are among the most widely used methods for chemical synthesis. The transition metal catalyst often used by industry and academic labs for these reactions is palladium. Palladium works well, but it’s rare, expensive, and toxic—which is why the Neidig and Gutierrez labs have been working to generate iron alternatives.

    Iron—though abundant, cheap, and relatively nontoxic—has been underdeveloped in part because when it is bound to carbon in these reactions, the resulting organoiron compound can be very unstable and challenging to control.

    While most cross couplings used in these reactions involve putting two molecules together, lead author Lei Liu, of Gutierrez’s group, managed to create three-component couplings, increasing the reaction’s potential for bonding with multiple compounds. Co-lead author Maria Camila Aguilera, a PhD student in Neidig’s group, then painstakingly analyzed exactly how the reaction works.

    Part of Aguilera’s work involved recreating the exact crystal structure of each of the four “species” of iron used in the reaction—in effect, creating a photo of each. She then characterized each of the species to determine which started the reaction, and the roles played by the other three at different stages of the reaction.

Adam Fenster/University of Rochester.

    “It was a very challenging project,” says the fourth-year PhD student who came to Rochester after completing a BS in chemistry at The National University of Colombia [Universidad Nacional de Colombia](CO). “But I was very excited about it because it allowed me to really dig into a very different type of chemistry.”

    Neidig says that Aguilera used an array of spectroscopy tools and a unique cryogenic infrastructure that allowed lab to “study unstable organoiron compounds that very few chemistry labs in the world can.” Her analysis “sets the framework to continue the development of iron-based reactions in a rational, mechanistically driven way,” he adds.

    A promising advance in drug development

    What are the prospects for implementation in drug development?

    “I think it’s a reaction that will be attractive to pharmaceutical companies,” Neidig says.

    “The reaction might require more tweaking and development,” he adds. But when it comes to that task, “the fundamental mechanistic framework we established will be so important in helping people think about how to make this system better and more efficient.”

    Both Aguilera and Neidig praised the close working relationship that developed with Gutierrez’s lab, especially given the scarcity of labs willing to work with iron catalyzed cross-coupling reactions because of the high risks and low rewards.

    “Osvaldo is an incredible collaborator,” Aguilera says. “He is very willing to share his knowledge, and so it was a pleasure to work with him.”

    The project is supported with funding from The National Institutes of Health (US) and The National Science Foundation (US).

    History

    Early history

    The University of Rochester traces its origins to The First Baptist Church of Hamilton (New York) which was founded in 1796. The church established the Baptist Education Society of the State of New York later renamed the Hamilton Literary and Theological Institution in 1817. This institution gave birth to both Colgate University(US) and the University of Rochester. Its function was to train clergy in the Baptist tradition. When it aspired to grant higher degrees it created a collegiate division separate from the theological division.

    The collegiate division was granted a charter by the State of New York in 1846 after which its name was changed to Madison University. John Wilder and the Baptist Education Society urged that the new university be moved to Rochester, New York. However, legal action prevented the move. In response, dissenting faculty, students, and trustees defected and departed for Rochester, where they sought a new charter for a new university.

    Madison University was eventually renamed as Colgate University (US).

    Founding

    Asahel C. Kendrick- professor of Greek- was among the faculty that departed Madison University for Rochester. Kendrick served as acting president while a national search was conducted. He reprised this role until 1853 when Martin Brewer Anderson of the Newton Theological Seminary in Massachusetts was selected to fill the inaugural posting.

    The University of Rochester’s new charter was awarded by the Regents of the State of New York on January 31, 1850. The charter stipulated that the university have $100,000 in endowment within five years upon which the charter would be reaffirmed. An initial gift of $10,000 was pledged by John Wilder which helped catalyze significant gifts from individuals and institutions.

    Classes began that November with approximately 60 students enrolled including 28 transfers from Madison. From 1850 to 1862 the university was housed in the old United States Hotel in downtown Rochester on Buffalo Street near Elizabeth Street- today West Main Street near the I-490 overpass. On a February 1851 visit Ralph Waldo Emerson said of the university:

    “They had bought a hotel, once a railroad terminus depot, for $8,500, turned the dining room into a chapel by putting up a pulpit on one side, made the barroom into a Pythologian Society’s Hall, & the chambers into Recitation rooms, Libraries, & professors’ apartments, all for $700 a year. They had brought an omnibus load of professors down from Madison bag and baggage… called in a painter and sent him up the ladder to paint the title “University of Rochester” on the wall, and they had runners on the road to catch students. And they are confident of graduating a class of ten by the time green peas are ripe.”

    For the next 10 years the college expanded its scope and secured its future through an expanding endowment; student body; and faculty. In parallel a gift of 8 acres of farmland from local businessman and Congressman Azariah Boody secured the first campus of the university upon which Anderson Hall was constructed and dedicated in 1862. Over the next sixty years this Prince Street Campus grew by a further 17 acres and was developed to include fraternities houses; dormitories; and academic buildings including Anderson Hall; Sibley Library; Eastman and Carnegie Laboratories the Memorial Art Gallery and Cutler Union.

    Twentieth century

    Coeducation

    The first female students were admitted in 1900- the result of an effort led by Susan B. Anthony and Helen Barrett Montgomery. During the 1890s a number of women took classes and labs at the university as “visitors” but were not officially enrolled nor were their records included in the college register. President David Jayne Hill allowed the first woman- Helen E. Wilkinson- to enroll as a normal student although she was not allowed to matriculate or to pursue a degree. Thirty-three women enrolled among the first class in 1900 and Ella S. Wilcoxen was the first to receive a degree in 1901. The first female member of the faculty was Elizabeth Denio who retired as Professor Emeritus in 1917. Male students moved to River Campus upon its completion in 1930 while the female students remained on the Prince Street campus until 1955.

    Expansion

    Major growth occurred under the leadership of Benjamin Rush Rhees over his 1900-1935 tenure. During this period George Eastman became a major donor giving more than $50 million to the university during his life. Under the patronage of Eastman the Eastman School of Music (US) was created in 1921. In 1925 at the behest of the General Education Board and with significant support for John D. Rockefeller George Eastman and Henry A. Strong’s family medical and dental schools were created. The university award its first Ph.D that same year.

    During World War II University of Rochester was one of 131 colleges and universities nationally that took part in the V-12 Navy College Training Program which offered students a path to a Navy commission. In 1942, the university was invited to join the Association of American Universities(US) as an affiliate member and it was made a full member by 1944. Between 1946 and 1947 in infamous uranium experiments researchers at the university injected uranium-234 and uranium-235 into six people to study how much uranium their kidneys could tolerate before becoming damaged.

    In 1955 the separate colleges for men and women were merged into The College on the River Campus. In 1958 three new schools were created in engineering; business administration and education. The Graduate School of Management was named after William E. Simon- former Secretary of the Treasury in 1986. He committed significant funds to the school because of his belief in the school’s free market philosophy and grounding in economic analysis.

    Financial decline and name change controversy

    Following the princely gifts given throughout his life George Eastman left the entirety of his estate to the university after his death by suicide. The total of these gifts surpassed $100 million before inflation and as such Rochester enjoyed a privileged position amongst the most well endowed universities. During the expansion years between 1936 and 1976 the University of Rochester’s financial position ranked third, near Harvard University’s(US) endowment and the University of Texas (US) System’s Permanent University Fund. Due to a decline in the value of large investments and a lack of portfolio diversity the university’s place dropped to the top 25 by the end of the 1980s. At the same time the preeminence of the city of Rochester’s major employers began to decline.

    In response the University commissioned a study to determine if the name of the institution should be changed to “Eastman University” or “Eastman Rochester University”. The study concluded a name change could be beneficial because the use of a place name in the title led respondents to incorrectly believe it was a public university, and because the name “Rochester” connoted a “cold and distant outpost.” Reports of the latter conclusion led to controversy and criticism in the Rochester community. Ultimately, the name “University of Rochester” was retained.

    Renaissance Plan

    In 1995 University of Rochester president Thomas H. Jackson announced the launch of a “Renaissance Plan” for The College that reduced enrollment from 4,500 to 3,600 creating a more selective admissions process. The plan also revised the undergraduate curriculum significantly creating the current system with only one required course and only a few distribution requirements known as clusters. Part of this plan called for the end of graduate doctoral studies in chemical engineering; comparative literature; linguistics; and mathematics the last of which was met by national outcry. The plan was largely scrapped and mathematics exists as a graduate course of study to this day.

    Twenty-first century

    Meliora Challenge

    Shortly after taking office university president Joel Seligman commenced the private phase of the “Meliora Challenge”- a $1.2 billion capital campaign- in 2005. The campaign reached its goal in 2015- a year before the campaign was slated to conclude. In 2016, the university announced the Meliora Challenge had exceeded its goal and surpassed $1.36 billion. These funds were allocated to support over 100 new endowed faculty positions and nearly 400 new scholarships.

    The Mangelsdorf Years

    On December 17, 2018 the University of Rochester announced that Sarah C. Mangelsdorf would succeed Richard Feldman as President of the University. Her term started in July 2019 with a formal inauguration following in October during Meliora Weekend. Mangelsdorf is the first woman to serve as President of the University and the first person with a degree in psychology to be appointed to Rochester’s highest office.

    In 2019 students from China mobilized by the Chinese Students and Scholars Association (CSSA) defaced murals in the University’s access tunnels which had expressed support for the 2019 Hong Kong Protests, condemned the oppression of the Uighurs, and advocated for Taiwanese independence. The act was widely seen as a continuation of overseas censorship of Chinese issues. In response a large group of students recreated the original murals. There have also been calls for Chinese government run CSSA to be banned from campus.

    Rochester scientists have secured national funding for a multi-institutional research effort that could alter the basic rules of chemistry.

    University of Rochester chemist Todd Krauss will lead a multi-institution effort to transform the field of chemistry, thanks to a $1.8 million dollar grant from The National Science Foundation (US). Chemists have long understood the tools they have available in order to create new molecules, such as changing the reaction temperature or using a catalyst—or doing both. Now, Krauss and his fellow researchers want to use light to facilitate previously impossible chemical reactions—in essence, by turning light into a catalyst.

    “This is a high-risk proposal,” says Krauss, a professor of chemistry and of optics at Rochester. “Will we be able to get enough molecules to strongly interact with the light to make a difference? If we do, it could be a paradigm shift in the field of chemistry.”

    Quantum principles applied to chemistry

    According to the principles of quantum science—which deals with the fundamental nature of atoms and subatomic particles—light is made up of small, discrete packets of energy. Krauss’s project calls for putting molecules in an optical cavity and using those discrete packets to change the energy states of electrons in the molecule. When that’s done, the molecules behave differently, opening the door for new bonding possibilities and ,thus, new chemistry.

    Molecules form through chemical bonding—the sharing of orbiting electrons. By changing temperatures or introducing catalysts chemists can manipulate how—or whether—electrons are shared. These interactions follow basic rules. For example, carbon-chlorine bonds are broken more easily than carbon-hydrogen bonds. Here, the team aims to use the application of quantum principles in order to change these basic rules to allow different bonds to break and reform.

    Krauss hopes to alter the spatial properties of electrons and as a result change the way molecules bond.

    “We can potentially move electrons uphill from one molecule to another—something that has been classically forbidden,” says Krauss. “Most electrons have spherical orbits. If we can move some of those electrons into non-spherical orbits, they’ll behave differently. Doing that would allow us to create new molecules.”

    QuEST for better medications, greener energy, new materials

    According to Krauss, this work represents a new way of developing chemical reactions—one with many potential benefits to society. “In theory, that could lead to new applications in fuel production, pharmaceuticals, and the manufacturing of plastics,” he says.

    The University of Rochester has a long tradition of quantum science with respect to strongly coupling light and atoms—defining the field of quantum optics for decades—dating back to the pioneering work of Leonard Mandel and Emil Wolf more than five decades ago. In QuEST, the team will build on that tradition by exploring how to strongly couple light with molecules in order to manipulate chemical reactions, pushing quantum optics into new and uncharted territory.

    Under the terms of the grant, Krauss will direct the NSF Phase I Chemical Innovation Center for Quantum Electrodynamics for Selective Transformations (QuEST). The QuEST research team includes fellow University of Rochester chemistry professors Pengfei Huo and William Jones, as well as optics professor Nick Vamivakas. Joining them on are Jillian Dempsey at The University of North Carolina–Chapel Hill (US), Nicolas Large and Zachary Tonzetich from The University of Texas–San Antonio (US), Teri Odom from Northwestern University (US), and Daniel Weix from The University of Wisconsin–Madison .

    “This is a three-year seed grant,” explains Krauss. “After a couple of years, we’ll compete for a Phase II grant—$20 million dollars over four years—to continue the research.”

The plan also revised the undergraduate curriculum significantly creating the current system with only one required course and only a few distribution requirements known as clusters. Part of this plan called for the end of graduate doctoral studies in chemical engineering; comparative literature; linguistics; and mathematics the last of which was met by national outcry. The plan was largely scrapped and mathematics exists as a graduate course of study to this day.

    Twenty-first century

    Meliora Challenge

    Shortly after taking office university president Joel Seligman commenced the private phase of the “Meliora Challenge”- a $1.2 billion capital campaign- in 2005. The campaign reached its goal in 2015- a year before the campaign was slated to conclude. In 2016, the university announced the Meliora Challenge had exceeded its goal and surpassed $1.36 billion. These funds were allocated to support over 100 new endowed faculty positions and nearly 400 new scholarships.

    The Mangelsdorf Years

    On December 17, 2018 the University of Rochester announced that Sarah C. Mangelsdorf would succeed Richard Feldman as President of the University. Her term started in July 2019 with a formal inauguration following in October during Meliora Weekend. Mangelsdorf is the first woman to serve as President of the University and the first person with a degree in psychology to be appointed to Rochester’s highest office.

    In 2019 students from China mobilized by the Chinese Students and Scholars Association (CSSA) defaced murals in the University’s access tunnels which had expressed support for the 2019 Hong Kong Protests, condemned the oppression of the Uighurs, and advocated for Taiwanese independence. The act was widely seen as a continuation of overseas censorship of Chinese issues. In response a large group of students recreated the original murals. There have also been calls for Chinese government run CSSA to be banned from campus.

    Research

    Rochester is a member of the Association of American Universities (US) and is classified among “R1: Doctoral Universities – Very High Research Activity”.

    Rochester had a research expenditure of $370 million in 2018.

    In 2008 Rochester ranked 44th nationally in research spending but this ranking has declined gradually to 68 in 2018.

    Some of the major research centers include the Laboratory for Laser Energetics, a laser-based nuclear fusion facility, and the extensive research facilities at the University of Rochester Medical Center.

    Recently the university has also engaged in a series of new initiatives to expand its programs in biomedical engineering and optics including the construction of the new $37 million Robert B. Goergen Hall for Biomedical Engineering and Optics on the River Campus.

    Other new research initiatives include a cancer stem cell program and a Clinical and Translational Sciences Institute. UR also has the ninth highest technology revenue among U.S. higher education institutions with $46 million being paid for commercial rights to university technology and research in 2009. Notable patents include Zoloft and Gardasil. WeBWorK, a web-based system for checking homework and providing immediate feedback for students was developed by University of Rochester professors Gage and Pizer. The system is now in use at over 800 universities and colleges as well as several secondary and primary schools. Rochester scientists work in diverse areas. For example, physicists developed a technique for etching metal surfaces such as platinum; titanium; and brass with powerful lasers enabling self-cleaning surfaces that repel water droplets and will not rust if tilted at a 4 degree angle; and medical researchers are exploring how brains rid themselves of toxic waste during sleep.
