Bio
Welcome to my homepage! I am currently a graduate student of the department of computational and applied mathematics at Rice University. I work under the supervision of Dr. Wotao Yin, and my research focuses on computational optimization with its theory and algorithm development, and applications in mathine learning and image processing.
I received a bachelor degree from the Dept. of Math at Nanjing University, China, in June 2007. From Sep. 2007 to July 2010, I studied and worked on operations research in AMSS of CAS, China. In July 2010, I got a master degree of management science, and in May 2013, I got my seconde master degree of arts from Rice University.
