Xuhua He (Chinese: 何旭华; pinyin: Hé Xùhuá, born 1979) is a Chinese mathematician and Chair Professor at the University of Hong Kong.[1]

Education and career

[edit]

In 2001, He graduated with a bachelor's degree in mathematics from Peking University.[2] In 2005, he earned his PhD from the Massachusetts Institute of Technology (MIT) with the thesis Some subvarieties of the De Concini-Procesi compactification under advisor George Lusztig.[3] As a postdoc research fellow, He was at the Institute for Advanced Study for the academic year 2005–2006[4] and Simons Instructor at the State University of New York at Stony Brook from 2006 to 2008. At Hong Kong University of Science and Technology he was an assistant professor from 2008 to 2012 and an associate professor from 2012 to 2014. From 2014 to 2019 he was a professor at the University of Maryland. In 2019 he became the Choh-Ming Li Professor of Mathematics at the Chinese University of Hong Kong[2] and joined the University of Hong Kong as a Chair Professor in 2023[5].

For the 2016–2017 academic year, He was a von Neumann Fellow at the Institute for Advanced Study.[4] In 2017 he was a Simons Visiting Professor at the Université Sorbonne Paris Nord (Paris 13 University).

Xuhua He’s research area is algebraic groups, representation theory, and arithmetic geometry. He is particularly interested in questions related to (finite and affine) Weyl groups and flag varieties, and their applications to arithmetic geometry and representation theory.[4]

In 1996, He won a gold medal at the International Mathematical Olympiad.[6] In 2013, he received the Morningside Medal in gold.[2] In 2018, in Rio de Janeiro he was an invited speaker with talk Some results on affine Deligne-Lusztig varieties at the International Congress of Mathematicians.[7] He was elected as a Fellow of the American Mathematical Society, in the 2025 class of fellows.[8]
