    Research Interest

    My research interests are focused on minimizing the impact of breast cancer from a diagnostic and therapuetic standpoint. Breast MRI is a powerful tool to facilitate the screening for and staging of breast cancer, and can be valuable adjunct to guide breast surgery. Oncoplastic surgical techniques optimize cosmesis after breast cancer surgery. Accelerated radiotherapy after lumpectomy decreases radiotherapy treatment times from 6 weeks to just 1 to 5 days.

    My main research interests include the surgical management of the morbidly obese, evidence-based surgery, and surgical education. Prior training in public health, health administration, and surgery provide a strong foundation from which to pursue these goals. The only effective and enduring treatment for morbid obesity is bariatric surgery. Like the previous public health epidemics of cancer and heart disease, surgery is the first responder to the obesity crisis.

    Through a 3 pronged comprehensive program: translational and clinical research, early detection and treatment, and promoting education, awareness and immunization, we are working towards the development of new strategies that will lead to the elimination of hepatitis B worldwide and reduce the threat and incidence of liver cancer. Our current research efforts focus on evaluating potential new diagnostic and treatment markers and novel targeted therapy for primary liver cancer.
