Research Interests

My overall research interests include utilizing integrative molecular epidemiology methods to illuminate pathways and risk factors for cancer, and to develop translational capacity of etiological research to inform on prevention and treatment efforts. The purpose of my research is to provide epidemiological data that could guide the development of primary and secondary cancer prevention, identify novel treatment strategies, and improve quality of life.
