Dr. Zhifu Xie
Professor
Bio
Dr. Zhifu Xie holds the Wright W. and Annie Rea Cross Endowed Chair in Mathematics and Undergraduate Research at USM since 2016. Zhifu earned his B.S. in Mathematics Education from Chongqing Normal University in 1998, his M.S. in Mathematics from Chongqing University in 2001, and his Ph.D. in Mathematics from Brigham Young University in 2006. He began his academic career as an assistant professor at Virginia State University in 2007 and was promoted to full professor in 2015. Zhifu’s outstanding research, teaching, service, and integration of knowledge earned him recognition as a 2012 SCHEV Outstanding Faculty Award Finalist (SCHEV refers to the State Council of Higher Education for Virginia). Zhifu actively engages undergraduate students in his cutting-edge mathematical research, overseeing their internships and individual projects, and finds great satisfaction in watching their progress.
