Personal Statement

♦ Virtual Visit: Delivering the same level of world-class care, with exceptional convenience. 

I am a Professor of Surgery (Endocrine and Minimally Invasive Surgery) at Weill Cornell Medical College and an Attending Surgeon at New York-Presbyterian Hospital/Weill Cornell Medical Center. I am also the Director of Robotic Surgery.

I have two major areas of focus:

(1) Endocrine tumors (Thyroid, Parathyroid, Adrenal, Neuroendocrine tumors)

Conventional thyroid, and parathyroid surgery and neck dissections are warranted and performed in the majoriy of these tumors. However, with current technology and advanced imaging more focal explorations can be performed with meticulous care to nerve identification and preservation. Novel robotic scarless techniques are performed to avoid neck incisions. Most of these cases are performed in an outpatient setting at our new DHK ambulatory surgical center with enhanced patient experience and new technology. In specific patients cases can be performed with mild sedation improving recovery and return to daily life. 

The approach to these disease is patient and tumor specific and involves management with a multidisciplinary team of experts. Overall, I perform well over 200 endocrine cases yearly.

(2) Foregut Disorders (GERD, Achalasia, Gastric and complex GI disorders).

I have focused on minimally invasive approaches for the management of these disorders and has been involved in the development of techniques to minimize scars through single incision and robotic surgery.

In the realm of reflux and foregut surgery I direct the motility center at Weill Cornell and provides a multidisciplinary approach to the management of reflux, esophageal, and gastric dysmotility. By centralizing care our team has improved patient experience and outcomes. We are focused on gastroesophageal reflux (GERD) and achalasia. I am involved in multiple studies assessing outcomes in reflux and esophageal surgery. During my time at Weill Cornell I have paved the way for robotic surgery here with over 150 cases a year. Using this technique, I have been able to perform complex surgery for benign and malignant gastric and esophageal conditions. I have also performed reoperative surgery using this technique and avoided the need for open surgery reducing patients’ hospitalization and time to return to their regular activity.

1. Reflux 

2. Achalasia

We perform outcome studies and use novel techniques to improve patients outcomes undergoing these procedures with scarless surgeries. Moreover, I focus on the workup of patients with a multidisciplinary team for imaging and biopsies as necessary. On the research side, I also have a team of researchers and is supported by the NIH with a grant aimed at identifying novel methods for targeting solid tumors allowing for another potential pathway for improved patient outcome. 

I am widely published in these fields and have presented my work nationally and internationally. There are in the field of Cancer and Surgery over 100 peer reviewed articles and 9 book chapters.

I have been repeatedly recognized by Castle Connolly as one of the "Best Doctors." I was also named by New York Magazine as one of New York's "Best Doctors." 

I belong to many prominent societies including:

American Association of Endocrine Surgeons

Society of Surgical Oncology

Surgical Society of the Alimentary Tract

Society of American Gastrointestinal and Endoscopic Surgeons

American College of Surgeons
