I am an Assistant Professor in the Department of Biostatistics at University of Michigan. Previously I was a postdoctoral fellow at the Harvard Data Science Initiative, working with Tianxi Cai and Eric Tchetgen Tchetgen in the Department of Biostatistics at the Harvard TH Chan School of Public Health. I did my Ph.D. in Biostatistics at University of Washington, under the supervision of Andrea Cook and Patrick Heagerty. I obtained my B.S. in Mathematics and Applied Mathematics with a minor in English at the Chu Kochen Honors College of Zhejiang University, China.
I am broadly interested in developing novel statistical methods that provide insights from high volume and high variability healthcare data such as electronic health records (EHR) data. In particular, my research focuses on developing causal inference methods tailored to EHR data, automated knowledge extraction and translation across healthcare systems, post-marketing drug safety surveillance and effectiveness, and high-throughput comparison of medical code endorsement and healthcare utilization. |
