Research Interests: Development and application of methods for recurrent event data, survival data, and longitudinal data; design and analysis of clinical trials. Collaborations include cancer research, blood and marrow transplant (BMT), tobacco use and smoking cessation, and health disparity research.

My methodological research interests include: recurrent gap time data analysis, dependent data resampling, survival analysis, and correlated data analysis.
