Yi Sun, Ph.D.

Yi Sun will be joining the Department of Mathematics at Columbia University as a postdoctoral research scientist. He completed his Ph.D. at the Massachusetts Institute of Technology under the supervision of Pavel Etingof. Prior to MIT, Dr. Sun received a M.A.St. in mathematics from the University of Cambridge with the support of the Churchill Scholarship and an A.B. and A.M. in mathematics from Harvard University.

Dr. Sun’s research focuses on representation theory, integrable systems, and their applications to special functions, integrable probability, and random matrices. His thesis work includes a structural study of the Macdonald-Ruijsenaars integrable system and its degenerations via quantum groups and a solution to the first case of the Etingof-Varchenko conjecture relating trace functions for quantum affine algebras to theta hypergeometric integrals. In the past, he has also worked on applications of stochastic processes to network methods in machine learning and axiomatic foundations of cost-sharing methods in economics.
