UBMD Internal Medicine


Infectious Disease

Accepting new patients

Professional Summary:

I provide inpatient infectious disease consultation services at both Erie County Medical Center (ECMC) and Buffalo General Medical Center (BGMC). In addition, I collaborate with the ECMC renal and pancreas transplant team to evaluate and treat infectious complications associated with solid organ transplantation. I feel honored to serve patients who receive a lifesaving organ in order to help live a normal life. Lastly, I see outpatients with various infectious disease problems at The YOU Center for Wellness at ECMC where I am currently the medical director.

I enjoy teaching medical students, residents and infectious diseases fellows the principles and practice of infectious diseases. The majority of my teaching is at clinical sites at ECMC and BGMC. However, I occasionally also give didactic lectures during specialty conferences and grand rounds.
