About me. I am a postdoctoral research fellow working with Dr. Susan Murphy in the Statistics Department at Harvard University. I received my PhD in Biostatistics from Johns Hopkins University in 2017, under the joint supervision of Dr. Constantine Frangakis and Dr. Michael Rosenblum. I received my Bachelor’s degree in Mathematics from Tsinghua University in 2012.

Research. My main research interests include:

  • Mobile health and reinforcement learning;
  • Causal inference: robust estimation in complex study designs (two-phase designs, double-sampling designs);
  • Clinical trials: adaptive enrichment trial design, multiple testing procedure, treatment effect heterogeneity, variable adjustment;
  • Computerization of semiparametric estimators, “deductive estimation”.
