Research Interests

I work as an epidemiologist and applied biostatistician. My routine work is to collaborate with clinicians and researchers for study design, data analyses, paper preparations and grant applications, especially in Cancer Prevention and Control Program at Siteman Cancer Center and in the Department of Surgery. My research interests include competing risks, longitudinal data analyses, developing and validating prognostic models with applications in cancer prevention and treatment.
