I am a Senior Research Staff in Computational and Applied Mathematics (CAM) Group at Oak Ridge National Laboratory (ORNL). I studied mathematics at Shandong University in China, receiving my Bachelor's degree and Master's degree in 2007 and 2009, respectively. I earned my Ph.D. in applied mathematics at Florida State University in 2012. I joined ORNL in 2012 as the Householder fellow in the Computational and Applied Mathematics Group within Computer Science and Mathematics Division. I was promoted to research staff at ORNL in 2015, and to Senior Research Staff in 2020. I have been holding a joint faculty appointment with the Department of Mathematics and Statistics at Auburn University since 2014. My research interests include high-dimensional approximation, uncertainty quantification, machine learning and artificial intelligence, stochastic optimization and control, numerical solution of stochastic differential equations, and model reduction for parametrized differential equations.
