Keying Ye Headshot



Keying Ye is a professor of statistics in the Department of Management Science and Statistics at The University of Texas at San Antonio. He previously worked at Virginia Tech (8/1990-8/2005) and Shanghai Jiaotong University (2/1985-7/1985). He received his Ph.D. degree in statistics from Purdue University, an M.S. degree in mathematics from the Institute of Applied Mathematics of Academia Sinica in China and a B.S. degree in mathematics from Fudan University in China. He has published articles in statistical methodology and application in various journals and books. He teaches a variety of courses and short courses in statistics. Currently he is an associate editor for Bayesian Analysis.
