Winnie Li

Wen-Ch'ing (Winnie) Li (; born December 25, 1948) is a Taiwanese-American mathematician and a Distinguished Professor of Mathematics at Pennsylvania State University. She is a number theorist, with research focusing on the theory of automorphic forms and applications of number theory to coding theory and spectral graph theory. In particular, she has applied her research results in automorphic forms and number theory to construct efficient communication networks called Ramanujan graphs and Ramanujan complexes.

Professional career Li graduated from National Taiwan University with a Bachelor of Science in mathematics in 1970. She then earned her Ph.D. in mathematics from the University of California, Berkeley, in 1974, under the supervision of Andrew Ogg.

Before joining faculty of Pennsylvania State University in 1979, she was a Benjamin Pierce assistant professor at Harvard University for 3.5 years from 1974 to 1977, and a tenure-track assistant professor at the University of Illinois at Chicago from 1978 to 1979.

Awards and honors In 2010, Li was the winner of the Chern Prize, given every three years to an outstanding Chinese mathematician. In 2012 she became a fellow of the American Mathematical Society. She was chosen to give the 2015 Noether Lecture.
