I have conducted research in endoscopic ultrasonography for the staging of upper and lower gastrointestinal cancers and pancreatic cancer. I have also conducted clinical trials in methods of treating the symptoms of gastrointestinal cancers, including laser and photodynamic therapy, feeding and drainage gastrostomy and jejunostomy tubes, and the use of stents to alleviate the symptoms associated with cancers obstructing the esophagus, stomach, bile duct, small and large intestine.

I graduated from Cornell University Medical College and subsequently did a residency in internal medicine at The New York Hospital, followed by specialty training in gastroenterology at Memorial Sloan Kettering Cancer Center. I am board certified in Internal Medicine and Gastroenterology.
