UBMD Internal Medicine


Infectious Disease

Hospital-based provider only

Professional Summary:

My clinical expertise is in the management of infections in patients who have undergone solid organ transplant or hematopoietic stem cell transplant. These patients require a dedicated diagnostic and treatment approach, as they are severely immunocompromised due to medications they receive to prevent organ rejection and are susceptible to a large number of pathogens (bacteria, fungi, viruses) that should not cause infections in healthy individuals. I also treat infections in immunocompromised patients secondary to cancer, chemotherapy, and medications (steroids, biologics, etc).

I provide consultation for inpatients in Buffalo General Medical Center (BGMC) and Roswell Park Cancer Institute, usually as a result of a referral from a primary care physician, but I also see patients referred from specialty services such as general surgery for surgical site infections, orthopedics for joint infections, cardiothoracic surgery for pacemaker infections, etc.

In my clinic at BGMC, I evaluate and treat patients with a variety of infections, as follow-up from recent hospitalizations and a referral from a primary care physician.

I also work at Erie County Department of Health Tuberculosis Clinic as Co-Medical Director.

I enjoy teaching medical students, residents, and fellows in inpatient consultation service and lectures in BGMC and Roswell. I see patients with residents and fellows, and we discuss their cases.
