I started my industrial career in July, 2020 as Research Scientist in Facebook Inc.

I obtained my PhD degree in June, 2020 in Department of Computer Science & Engineering, University at Buffalo-SUNY. My research interest is machine learning, especially deep learning & bayesian learning, with applications in natural language processing. My PhD advisors are Dr. Changyou Chen and Dr. Wen Dong. Prior to that, I have finished bachelor and master in applied physics in University of Science and Technology of China and University of Houston, respectively.
