Associate Professor



Biography

Prof. Ip is currently an Associate Professor in the HKUST Department of Mathematics. He joined HKUST as an Assistant Professor in June 2018. Prior to his appointment in HKUST, he stayed in Japan for 6 years as an Assistant Professor at Kyoto University from 2015-2018, and a Project Researcher at Kavli IPMU, Tokyo University from 2012-2015. He grew up in Hong Kong and was an IMO Medalist for the Hong Kong team in 2002. He received his B.Sc. in Mathematics and Physics from HKUST, and his Ph.D. in Mathematics from Yale University under the supervision of Igor Frenkel.
