Xinkai Zhou is a senior statistician at the Department of Medicine Statistics Core. He has collaborated with investigators from the Department of Medicine, Stein Eye Institute, Jonsson Comprehensive Cancer Center, Cedars-Sinai Medical Center and other institutions on a variety of clinical trials and biomedical research projects. His methodological research focuses on developing scalable statistical inference tools for biobank scale (N >1 million), high-dimensional, and repeatedly collected modern health data (Electronic Medical Records, wearable devices, etc.). Besides statistics, he enjoys soccer, music, history, and traveling.
