Abstract

About the speaker

Yitwah Cheung completed his PhD at the University of Illinois at Chicago in 2000 studying ergodic properties of rational billiards, which earned him a Clay Liftoff Award. He taught at Northwestern University as Ralph Boas Assistant Professor before joining the Mathematics Department at San Francisco State University (SFSU) as tenure-track assistant professor in 2005. In 2010 his research program was recognized by NSF CAREER Award, in part for his contribution to the problem of computing Hausdorff dimension of singular vectors. Apart from supervising over a dozen masters' theses, he has also served as graduate director and associate chair of the Mathematics Department at SFSU. In 2018, Cheung moved to China with his family, joining Yau Mathematical Sciences Center at Tsinghua University where he has since remained.
