Summary of Research Activity: 

My professional goal is to provide individual risk assessment and counseling to develop a plan for treating neoplasia before metastatic cancer develops in people at high-risk of cancer because of genetic factors. My training and board certification in Medical Genetics have provided me with expertise and experience caring for people at high-risk for breast cancer due to mutations in BRCA1, BRCA2, APC and mismatch repair genes genes. I will couple this with my laboratory background to translate advances understanding additional genes influencing cancer risk into new clinical tests for my patients. I will seek to apply these advances to all of my patients, regardless of racial, ethnic, or socio-economic background.

A second research direction addresses appropriate targeting of chemoprevention strategies. I am participating in a project to test the safety of using DFMO and sulindac as a chemopreventive strategy in children with FAP, which we hope to follow with a study of efficacy.
