UBMD Internal Medicine



Hospital-based provider only

Professional Summary:

My clinical focus is providing excellent clinical care to patients with a broad range of gastroenterological disorders--particularly those with liver diseases such as hepatitis, alcoholic and non-alcoholic liver disease, cirrhosis, ascites and portosystemic encephalopathy. I work exclusively at Erie County Medical Center where I serve as chief of gastroenterology. I perform upper endoscopy, colonoscopy and paracentesis on inpatients and outpatients at that facility. My patient-care efforts include digital outreach: I co-authored an article for the inaugural issue of the patient-oriented online magazine “HCV Next.”

I also provide telehealth—i.e, telephone and secure messaging consultation and follow up to patients in need of this type of long-distance care. This provides more accessible health care to patients who reside a distance from Buffalo, saving them the time and expense of traveling, or to patients for whom travel is inconvenient.

I teach the medical students at the University at Buffalo in the classroom, on the wards and in the clinic, how to diagnose and treat liver disease. I have been recognized for my educational skills and have received several awards for teaching. My current research focuses on the delivery of care to patients with liver disease who have limited access to specialists. I conduct studies evaluating tele-gastroenterology, tele-hepatology, telephone medicine and palliative care in patients with advanced liver disease, and I routinely involve and mentor UB fellows, internal medicine residents and medical students in these ongoing studies. The aim of this research is to help provide more accessible health care to patients with physical challenges, those patients who have trouble traveling and those patients whose remote geographic location prevents them from otherwise receiving high-quality health care.
