About Me

I am a board-certified surgeon who cares for patients with benign and cancerous endocrine and neuroendocrine (carcinoid) tumors. This includes diseases of the parathyroid, thyroid, adrenal glands and the gastrointestinal tract. Because these conditions are often complex, I work closely with colleagues in endocrinology, medical oncology, radiology, gastroenterology and pathology to deliver state-of-the art multidisciplinary care. Our team of physicians and nurses works tirelessly to deliver the best possible medical, surgical and follow-up care. Sometimes multiple treatments can exist for these conditions and it’s critical that patients have an in-depth understanding of these options. If surgery is necessary, our team will answer questions and explain what patients might anticipate leading up to and after surgery.

Recovery after surgery can be difficult and for this reason I use minimally invasive surgical approaches when possible. With these techniques, patients have less pain and can recover faster than they otherwise would. Sometimes minimally invasive approaches cannot be used, and in these instances I work closely with my anesthesia colleagues to provide the most comfortable experience possible.

In addition to the endocrine and neuroendocrine conditions listed above, I also have a special interest in caring for patients with genetic and familial endocrine diseases including Multiple Endocrine Neoplasia (MEN) I, IIa, and IIb, von Hippel-Lindau Syndrome (VHL), paraganglioma syndromes, Cowden’s Disease, familial hyperparathyroidism, familial medullary thyroid cancer, and Carney Complex. Because these syndromes can lead to different types of tumors and symptoms, each patient requires highly individualized care. Memorial Sloan Kettering has a long history of treating patients with these conditions, and my goal is to advance the knowledge and treatment options available.

My laboratory research focuses on mechanisms of thyroid tumor progression and responses to therapy in the Human Oncology and Pathogenesis Program. Using genetically accurate models of cancer, we explore why certain tumors are more aggressive than others (such as poorly differentiated or anaplastic thyroid cancers) and how best to treat these with various interventions.  For this work, I have been awarded multiple grants including one from both the American Thyroid Association and the Thyroid Cancer Survivors’ Association.

I have lectured on endocrine and neuroendocrine disease topics all over the country and have published numerous articles on how best to treat patients. Improving the quality of care patients receive is my top priority. After getting a diagnosis, patients can have a lot of anxiety about the next step. My role is to help patients though this and get them the best possible treatment.

Clinical Trials

As home to one of the world’s top cancer research centers, Memorial Sloan Kettering is typically involved in more than 900 clinical trials at a given time. Currently, clinical trials focused on the conditions I treat are enrolling new patients.
