About Me
Hello! I am a Postdoctoral Research Associate in the Statistical Laboratory, Department of Pure Mathematics and Mathematical Statistics (DPMMS) at the University of Cambridge working with Dr. Qingyuan Zhao. I obtained my Ph.D.in the Department of Biostatistics at University of Michigan advised by Dr. Walter Dempsey and Dr. Zhenke Wu.
Research Theme:
My doctoral research focuses on developing robust and efficient methodologies to evaluate causal excursion effects in sequential, adaptive intervention experiments. My work leverages new experimental approaches, such as micro-randomized trials (MRTs), as well as causal inference and supervised learning methods. The general theme of my research is to advance a more relevant, valid, and precise assessment of digital health intervention effects in the new context of time-varying treatments and repeated outcomes with clustering, interference, and high-dimensional nuisance parameters.
Keywords:
Causal Inference; Causal Excursion Effect; Just-In-Time Adaptive Interventions; Micro-randomized Trials; Mobile Health; Time-varying Moderation Effect; Double robustness.
