My primary research interests include clinical trials and epidemiological studies related to screening for and prevention of cancer, as well as the development of biostatistical and epidemiologic methods. My expertise is in cancer screening, colorectal cancer, medical device evaluation, biostatistics, epidemiologic methods, and clinical trial design. I am currently leading multiple trials and studies regarding colorectal, prostate, lung, and ovarian cancer, and have also helped establish a registry for Parkinson’s Disease research.
