I am a breast surgeon with 25 years of experience caring for patients with breast cancer, and I work collaboratively with other breast cancer specialists on Memorial Sloan Kettering’s multidisciplinary breast cancer disease management team. After receiving surgical training in both oncologic and reconstructive procedures, I became interested in joining these two disciplines to provide improved care to breast cancer patients, and I have developed a special expertise in this growing field of oncoplastic surgery. Currently, I am completing a textbook to help other breast surgeons enhance cosmetic results while performing surgery to treat breast cancer.
My research interests have covered different aspects of breast cancer and quality of care in surgery. I have been the principal or co-principal investigator on research grants from the Avon Breast Cancer Foundation, the United States Veterans’ Administration, and the American College of Surgeons. I was the principal investigator and currently am the co-holder of a US patent for Detectably Labeled Porphyrin Compound for Identifying the Sentinel Lymph Node (US 6,458,336 B1; October 1, 2002). I have led an important investigation exploring the clinical significance of micro-metastasis detected by immuno-histopathology in patients with ductal carcinoma in-situ (DCIS). The results of that research have helped clinicians seriously reconsider the role and the indication of sentinel-node dissection in patients with DCIS.
My research has also covered different clinical aspects of breast cancer in minority populations in the US, quality of care in surgery, and breast cancer in men, and I have written more than 55 book chapters, manuscripts, and editorials on these subjects. I am a reviewer for and sit on the editorial boards of many leading medical journals.
I was the one of the principal investigators who validated the applicability of the National Surgical Improvement Program (NSQIP) in the private sector, which has since been adopted by the American College of Surgeons as a yardstick for quality improvement. I am one of the founding members of the National Accreditation Program for Breast Centers and have been serving on their board of directors and as a chair of the information technology and quality improvement committee.
I am an active member of many leading professional societies including the American College of Surgeons, the Society of Surgical Oncology, the American Society of Breast Surgeons, and the American Society of Breast Diseases. I am currently the Program Chair for the 2011 meeting of the American Society of Breast Surgeons. I also served as President of the New York Metropolitan Breast Cancer Group from 2009 to 2010.
