Welcome to Dr. Phan's homepage! I am an associate professor at the Department of Mathematics, University of Tennessee-Knoxville. I received my B. S. degree in mathematics in 2000 from the University of Science (Ho chi Minh City-Vietnam), and my Ph.D. in 2007 from the University of Minnesota (Twin Cities-Minnesota-US). My research is in partial differential equations. I study existence, uniqueness, and regularity estimates of solutions. I also work on nonlinear dynamics of solutions, and optimal control problems in mathematical biology. I love outdoor activities (walking, biking, and hiking), and enjoy hanging with my family and friends at local coffee shops. I like gardening and regularly practice Taekwondo. The above math formula is an a-priori estimate of the unknown solution $u$ of a class singular-degenerate coefficient PDEs. This formula appears in my recent work, which is a joint work with Hongjie Dong.
