About me: I received my Ph.D. in Computer Science from Georgia Tech in 2007, co-advised by Ling Liu (CS) and Bill Rouse (ISYE). Before that, I earned two M.S. degrees from Stanford University: one in Computer Science in 2001 and one in Engineering-Economic Systems & Operations Research in 2000. My undergraduate degree is a B.A. in Economics (magna cum laude) from Duke University in 1996. I joined the faculty at Texas A&M in 2007. I spent most of my sabbatical in 2015 at Google as a Visiting Scientist in Ed Chi's group. I've been honored to receive an NSF CAREER award, DARPA Young Faculty award, a AFOSR Young Investigator award, as well as several teaching awards. Recently co-organized WSDM 2020 with Xia "Ben" Hu. Thank you to everyone who helped make this a successful conference!
