I am a surgical oncologist with board specialization in colorectal surgery and an interest in primary, metastatic, and recurrent cancers of the appendix, colon, rectum, and anus. My expertise is in laparoscopic (minimally invasive) surgery to remove these tumors with minimal trauma to the patient. I also have an interest in methods to preserve sphincter function and to maintain bladder and sexual function through nerve-sparing surgical techniques.
My clinical research focuses on improved staging and methods to predict outcome following cancer surgery. I monitor and update the MSKCC Colorectal Cancer Database, which tracks patient outcome to ensure quality of care. My laboratory research focuses on understanding and targeting mechanisms of tumor spread and metastasis.
I have recently been appointed Program Chair of the Annual Meeting of the American Society of Colon and Rectal Surgeons. I am a member of the AJCC (American Joint Committee on Cancer) staging committee, which develops the staging system for colorectal cancer, and the NCCN (National Comprehensive Cancer Network) colorectal database committee, as well as a cadre member of the GI committee of the CALGB cooperative group.
I have coauthored many papers and book chapters on a variety of topics, including laparoscopic surgery, colon and rectal cancers, rare anorectal tumors, staging of cancer, predictors of outcome following surgery, and mechanisms of tumor metastasis. I lecture all over the country on the management of colorectal and anal cancer as well as laparoscopic surgery.
