Research Interests

My major research area is survival analysis. More generally, I am interested in statistical inference for point process data (e.g., recurrent events); statistical 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; asymptotics (theory and approximation); and various problems in statistical computing.
