Lei Yang is an associate professor at Sichuan University. He got his PhD at Ohio State University with Nimish Shah in 2014 and held postdoc positions at Yale (with Margulis, Fall, 2014), MSRI (Spring, 2015), and Hebrew University (with Lindenstrauss, 2015-2017), before moving to Sichuan. His research focuses on homogeneous dynamics and their applications to Diophantine approximation. With collaborators, he has made serious progress on several topics in Diophantine approximation, including badly approximable vectors, and multiplicative Diophantine approximation. His achievements in these areas have been published/accepted in high quality peer reviewed journals, which include Duke Mathematical Journal and Geometric and Functional Analysis - GAFA (two papers: in 2019 and 2021).
