Ph.D. 2009 City University of Hong Kong (jointly awarded by University of Science and Technology of China)
B.S. 2004 University of Science and Technology of China

I joined the Department of Mathematics at the University of Louisiana at Lafayette in August 2016. Before that, I had been working at City University of Hong Kong, Memorial University of Newfoundland, Southeast Missouri State University, and York University. My research interests are mainly in the interdisciplinary areas of applied analysis, computational mathematics, and mathematical biology. I am actively seeking for collaborations with various researchers from different backgrounds. Especially, I enjoy advising graduate and undergraduate students on their research projects. I like to communicate mathematics in terms of teaching, publication, presentation and discussion. My other hobbies include swimming, hiking, reading, playing chess, piano and badminton.
