I am an associate professor of Mathematics at the University of Arizona (UA). I am an editor of the jounral STAT.
I received my B.S. in Mathematics from Peking University, and Ph.D. from the Department of Mathematics at Stony Brook University.
I spent one year as a research associate at the statistics lab, Princeton University before joining the UA.
I am co-organizer of UA TRIPODS research working group (RWG) 6.
I am coaching Sunrise Drive Mathleague Club with my colleagues Selena Niu and Helen Zhang. In 2020-2021, the club has been expanded to all four elementary schools in CFSD16.Show Less
