Research Interests

My major research area is survival analysis. More generally, I am interested in semiparametric methods for missing and censored data; statistical learning methods for risk and outcome prediction in medicine, epidemiology and public health; statistical and computational methods for high dimensional data; statistical methods for evaluating the cost and quality of health care; and, applications in cancer, psychiatry (e.g., suicide) and neurological disease (e.g., Huntington’s Disease).
