Faculty Appointments


My passion is direct patient care that is comprehensive in treating the "whole patient" and family-centered by including children and their families in the development of the care plan. As a pediatric hospitalist, I provide care to hospitalized pediatric patients of all ages from infancy thru adolescence that are acutely ill or have medically complex conditions. This includes providing pediatric consultation to subspecialty and surgical patients and coordination of care among multiple provider teams.

Education of patients and their families as well as medical students, residents, and colleagues is a fundamental part of my patient care activities. I also have a specific interest in development of individualized care plans for patients with complex medical care needs.

Professional Background

Barbara Asselin, MD, an attending physician and faculty member at URMC for over 25 years, graduated from Boston College, Boston, MA and then received her medical degree from University of Rochester School of Medicine & Dentistry. After completing her residency in Pediatrics at University of Massachusetts, Worcester, MA, she returned to Rochester and completed fellowship training in Pediatric Hematology/Oncology at the University of Rochester.

As a board-certified pediatrician and pediatric hematologist/oncologist, Dr. Asselin has provided care for pediatric patients with cancer and blood disorders, conducted research trials in pediatric malignancies, served as Principal Investigator to the Children's Oncology Group and Dana-Farber Leukemia Consortium, and authored numerous research studies, articles and book chapters related to her clinical and research interests. Since 2009, she has worked as an academic hospitalist in the division of Pediatric Hospital Medicine providing comprehensive inpatient medical care for children with acute and chronic illnesses. Dr. Asselin's academic interests include clinical research to improve the care of patients with pediatric cancers, medical education for medical students and residents, and development of individualized patient care plans for patients with complex, multispecialty needs.


Dr. Asselin's research expertise is in clinical trials and clinical research to improve the care of patients with pediatric cancers. She serves as study investigator for two major international cooperative research groups, the Children's Oncology Group and the Dana-Farber Leukemia Consortium.

Through these groups she is actively involved in design and development of a number of studies of the treatment and biology of acute lymphoblastic leukemia (ALL) and non-Hodgkin lymphoma (NHL). Her specific areas of expertise are L-asparaginase pharmacology and immunology in treatment of ALL, treatment of T-cell disease (ALL and NHL), and the role of cardioprotection in prevention of cardiotoxocity in long-term survivors.
