Charlotte Chan, assistant professor of mathematics in LSA, was awarded the fellowship for her work in representation theory, the study of symmetries using linear algebra.

Representation theory is a subject that arises in fields of science such as physics, computer science and chemistry. For example, the representation theory of the rotational symmetries of a circle is Fourier analysis, a field that has extensive applications to science and engineering, Chan said.

In particular, she focuses on representation theoretic problems “rooted in deep interactions with number theory and algebraic geometry.”

“How can we use polynomials (algebraic geometry) to produce spaces with symmetries (representation theory) to understand phenomena about prime numbers (number theory)?” Chan said. “This is an old question, with lots of rich history and exciting new developments. It’s a privilege to get to explore this picture — even seeing one new link is very invigorating.”

Awarded annually by the Alfred P. Sloan Foundation since 1955, the fellowships honor extraordinary U.S. and Canadian researchers whose creativity, innovation and research accomplishments make them stand out as the next generation of leaders.

Candidates must be nominated by their fellow scientists, and winners are selected by independent panels of senior scholars on the basis of a candidate’s research accomplishments, creativity and potential to become a leader in their field.

More than 1,000 researchers are nominated each year for 118 fellowship slots. Winners receive a two-year, $75,000 fellowship that can be used flexibly to advance the fellow’s research.

“My favorite aspect of mathematics is when a ‘dictionary,’ or correspondence, between two different areas allows one to gain new perspective, for example by translating difficult questions on one side into tractable questions on the other side,” Chan said. “It is an honor to be selected as a Sloan Research Fellow. I’m excited to pursue new ideas and new directions, with the flexibility and support provided by this fellowship.”

A Sloan Research Fellowship is one of the most prestigious awards available to young researchers, in part because so many past fellows have gone on to become towering figures in science.

Renowned physicists Richard Feynman and Murray Gell-Mann were Sloan Research Fellows, as was mathematician John Nash, one of the fathers of modern game theory. For five of the past six years, the recipients of the Nobel Prize in Physics have included former Sloan Fellows: Andrea Ghez (2020), James Peebles (2019), Donna Strickland (2018), Kip Thorne (2017) and Duncan Haldane (2016).

In fact, 53 Sloan Fellows have received a Nobel Prize in their respective field, 17 have won the Fields Medal in mathematics, 69 have received the National Medal of Science and 22 have won the John Bates Clark Medal in economics, including every winner since 2007.

“Today’s Sloan Research Fellows represent the scientific leaders of tomorrow,” said Adam Falk, president of the Sloan Foundation. “As formidable young scholars, they are already shaping the research agenda within their respective fields — and their trailblazing won’t end here.”

Fellows from the 2022 cohort are drawn from a diverse range of 51 institutions across the United States and Canada, from large public university systems to Ivy League institutions to small liberal arts colleges.

Open to scholars in seven scientific and technical fields — chemistry, computer science, Earth system science, economics, mathematics, neuroscience and physics —the Sloan Research Fellowships are awarded in close coordination with the scientific community.
