Shinpei Nakamura-Sakai
I am a Ph.D. student in Statistics and Data Science at Yale University. My research interest lies in causal inference, synthetic data generation, and machine learning application. In application, I enjoy applying theory to solve problems related to finance, medicine, social science, and sports. I am very fortunate to be advised by Professor Jas Sekhon and Professor Laura Forastiere.
