I am a Principal Machine Learning Scientist at the AI Evaluation Lab of Stanford University, Department of Radiology. Previously, I was a founding member and the Data Science Lead at LVIS corporation, a Palo Alto based start-up innovating how neurological diseases are treated with cutting-edge neuroscience findings and AI. I received my Ph.D. in Electrical Engineering from Stanford University, M.S. from the University of California Los Angeles, and B.S. from Zhejiang University, China. My research interests lie in driving innovation in medical AI, with a focus on achieving better clinical decisions, advancing personalized medicine, and streamlining healthcare efficiency.
