### Biography

I was born and raised in Tianjin China (a beautiful city 80 miles from Beijing). Before entering college, three excellent teachers, Ms. Hong Liu, Ms. Haiying Wang and Mr. Shengli Duan, raised my interest in the study of mathematics. In 2005, I joined the Department of Modern Mechanics at University of Science and Technology of China. One year later, I transferred to the Math Department and studied pure math, especially analysis. After receiving my Bachelor's degree of Mathematics in 2009, I started my graduate studies at Brown University and worked with Professor Chi-Wang Shu on Numerical Analysis. My work mainly focused on high order numerical methods for time-dependent problems. It includes three parts: Approximations to delta-functions, Superconvergence of discontinuous Galerkin methods and Numerical cosmology. After obtaining my Ph.D. degree in 2013, I joined the Department of Mathematical Sciences at Michigan Technological University.
