Jiaqi Tong

I am a third-year PhD student in Biostatistics at Yale School of Public Health under the supervision of Prof. Fan Li.

My research focuses on developing novel methods in causal inference, with specific interests in principal stratification, mediation analysis, and treatment effect heterogeneity. My broader theoretical interests include semiparametric and nonparametric inference, statistical learning, and the method of sieves. My work is motivated by the application of these methods to clinical trials, observational studies, and social experiments.

During my master's studies, I also developed applied work in clinical trial design and sample size estimation under the supervision of Prof. Guangyu Tong and Prof. Fan Li.

I am always open to new research collaborations and discussions. Please do not hesitate to contact me via email.
