Vice Chair of Education

William “Jerry” Durbin, MD
Professor of Pediatrics and Internal Medicine
Director, Pediatric Education Division
Director of Pediatric Infectious Disease Consultation Service

Jerry grew up right here in Massachusetts and attended Newton South High School . He then headed north to Dartmouth College where he majored in English and minored in outdoor life. He attended medical school at Columbia University in the Big Apple, following which he returned to Dartmouth for an internship in medicine. After a two year stint at the NIH he saw the light and moved back to Massachusetts to complete two years of pediatric residency at Children’s Hospital Boston. He then accepted a combined fellowship in pediatric and adult infectious disease at Beth Israel Hospital – Children’s Hospital Medical Center – Sidney Farber Cancer Center in Boston .

Jerry came to Worcester City Hospital in 1979. At that time, UMass Medical School had just started, he was asked to join the new faculty, and he has been a familiar face in the halls at UMass ever since. He has remained very active in infectious disease and HIV care and has a busy academic clinical practice. Jerry is a well-respected clinician and teacher. He is often asked to write articles and chapters on pediatric infectious disease topics, including case reports in the NEJM and articles for Pediatrics in Review. Jerry has won numerous teaching awards over the last 20 years. One of Jerry’s major contributions to the Pediatric Residency Program at UMass has been his strong leadership in involving current pediatric residents in the selection of the next class of interns, an unusual and very successful component of the pediatric residency. Jerry served as pediatric residency program director until 2011.

When he is not at the hospital, you can find him hiking in the White Mountains, avidly watching the Red Sox, catching up with his sons Adrian and Will, or preparing for his next trip to visit his daughter, Ali, and granddaughters, Chely and Kayala, in Guatemala.

Tina is a full time pediatric infectious disease specialist who, in addition to clinical ID, works with infection control, antibiotic stewardship and undergraduate medical education. Most of her free time is spent with her children Amelia (3), John (3) and Theo (8 months).

Without enough time to participate in all of her own interests; global health, research, medical education, she enthusiastically guides and supports residents in these endeavors.
