Fan Li
Professor of Statistical Science

My main research interest is causal inference and its applications to health, policy and social science. I also work on the interface between causal inference and machine learning. I have developed methods for propensity score, clinical trials, randomized experiments (e.g. A/B testing), difference-in-differences, regression discontinuity designs, representation learning. I also work on Bayesian analysis and statistical methods for missing data. I am serving as the editor for social science, biostatistics and policy for the journal Annals of Applied Statistics.

Current Research Interests

My current research interests are four fold. First, I am developing statistical methods to incorporate causal inference techniques into the design and analysis of clinical trials or generally randomized experiments, e.g. constructing external controls of clinical trials from real world data, best practice of covariate adjustment in randomized trials. Second, I am exploring the interface between causal inference and machine learning, e.g. how to borrow insights from causal inference into fundamental problems in machine learning such as measuring feature importance. Third, I am investigating how to analyze natural experiments with complex data. Fourth, I am developing computational and software tools to bridge the theory and practice of causal inference (aka comparative effectiveness research).
