About
I'm now a fifth-year PhD student in the Department of Computer Science and Engineering at Washington University, adviced by Prof. Chenyang Lu. I'm also working closely with Prof. Thomas Kannampallil, Dr. Sunny Lou, and Prof. Cristina Vazquez Guillamet at Washington University School of Medicine. I received my Bachelor's and Master's degree at the Northwestern Polytechnical University, China. My CV [pdf].
Research Interest
My current research interest is applied machine learning, especially learning from Electronic Health Records (EHR) for clinical prediction. My previous research includes machine learning problems such as constrained clustering, semi-supervised learning and imitation learning, as well as their applications in spatio-temporal data mining.
