Zhiwei Yun

Zhiwei Yun (Chinese: 恽之玮; pinyin: Yùn Zhīwěi;^[4] born September 1982) is a Professor of Mathematics in Yale University specializing in number theory, algebraic geometry and representation theory, with a particular focus on the Langlands program. Before moving to Yale University in 2016, he held assistant and associate professorships at Stanford University from 2012 to 2016 and was a C. L. E. Moore instructor at Massachusetts Institute of Technology from 2010 to 2012.

Biography

Yun was born in Changzhou, China.^[1] As a high schooler, he participated in the International Mathematical Olympiad in 2000; he received a gold medal with a perfect score.^[2] Yun received his bachelor's degree from Peking University in 2004. In 2009, he received his Ph.D. from Princeton University, under the direction of Robert MacPherson.^[5][6]

Yun was awarded the SASTRA Ramanujan Prize in 2012 for his "fundamental contributions to several areas that lie at the interface of representation theory, algebraic geometry and number theory."^[7]

His collaborations with Wei Zhang, Xinyi Yuan and Xinwen Zhu have received attention in publications such as Quanta Magazine and Business Insider.^[8][9] In particular, his work with Wei Zhang on the Taylor expansion of L-functions is "already being hailed as one of the most exciting breakthroughs in an important area of number theory in the last 30 years."
