About

I am a researcher in the field of machine learning. I got my PhD in Computer Science at Boston University, where I was advised by Prof. Stan Sclaroff and Prof. Steven Rosenberg, and also worked with Prof. Henry Lam. Prior to BU, I obtained my Bachelor's degree at Tsinghua University and Master's degree at National Laboratory of Pattern Recognition.

I am interested in bringing new mathematical perspectives and tools to characterize essential yet underexplored aspects of machine learning problems, especially those arising in computer vision. Such efforts may lead to new principled models and algorithms suitable for solving real-world problems. I use methodologies mainly from statistics, stochastic optimization, functional analysis, and differential geometry.
