My interests are the identification of modifiable risk factors for common cancers--colorectal, breast, and endometrium. Increasingly, my work has focused on better characterizing individuals at risk because of the joint presentation of environmental and genetic factors. Over the past 20 years, I have conducted several large population based case-control studies of cancer etiology. Cases enrolled in these studies now form the basis for cohorts to examine factors associated with survivorship. I am also interested in the observational evaluations of screening efficacy.
