Professional Employment

Dr. Jia received his B.S. in Mathematics and Applied Mathematics from Peking University in 2009 and received his Ph.D. in Probability and Statistics from Peking University in 2015 under the guidance of Prof. Minping Qian and Prof. Daquan Jiang. After completion of his degree, he moved to Dallas, where he worked at University of Texas at Dallas as a Research Associate supervised by Prof. Michael Q. Zhang and Prof. Min Chen. Then he moved to Detroit in 2019, where he worked at Wayne State University as a Research Associate supervised by Prof. George G. Yin. Since 2020, Dr. Jia joined CSRC as an Assistant Professor.
