Gordon J. Strewler, MD

Vice-Chair for Mentorship, Department of Medicine 

Gordon "Buck" Strewler grew up in northern Minnesota and graduated summa cum laude from Dartmouth College in 1968. He graduated cum laude from Harvard Medical School Class of 1971 and then served as an intern and resident at Peter Bent Brigham Hospital, the predecessor of Brigham and Women's. After clinical and research training in Endocrinology-Metabolism at the National Institutes of Health, he joined the faculty of the University of California, San Francisco in 1979. He is an expert in calcium and bone metabolism; his laboratory identified, sequenced and cloned the parathyroid hormone-related protein, PTHrP, developed the first assay to detect PTHrP in patients with hypercalcemia, and led the way to the understanding of its role in disease. He was Professor of Medicine and Chief of the Endocrine Unit at the SFVAMC and also directed the UCSF Endocrinology Fellowship Program for many years.

Dr. Strewler returned to Boston in 1996 to become Chief of Medicine at the West Roxbury VA Medical Center (now part of the VA Boston Healthcare System), Professor of Medicine at Harvard Medical School, and Vice Chair of the Department of Medicine at Brigham and Women's Hospital.

Peter F. Weller, MD

Vice Chair for Research, Department of Medicine

Dr. Peter Weller is Professor of Medicine at Harvard Medical School, Co-Chief of the Infectious Diseases Division and Chief of the Allergy and Inflammation Division in the Department of Medicine at Beth Israel Deaconess Medical Center. He also serves as the Vice-Chair for Research for the Department of Medicine, Beth Israel Deaconess Medical Center and as a member of the Executive Committee of the Department of Medicine, Harvard Medical School.

Dr. Weller's research studies, supported principally by longstanding NIH RO1 grants, have focused on delineating basic mechanisms of leukocyte functioning in forms of inflammation. The two principal areas of investigation are: 1) the immunobiology of eosinophilic leukocytes and 2) the intracellular regulation and compartmentalization of inducible mediators of inflammation in neutrophils and other leukocytes. These investigations are pertinent to the roles of eosinophils in allergic and anti-parasite immune responses and to the cellular biology of leukocytes underlying their functions in infectious and immune inflammatory responses.

Dr. Weller's clinical areas of interest and expertise include parasitic infectious diseases and allergic diseases. In both areas, Dr. Weller has a record of continuing contributions, including as the parasitic diseases Editor for the Journal of Infectious Diseases and UpToDate and the Co-Editor of the very well-reviewed text, Tropical Infectious Diseases: Principles, Pathogens and Practice, now in its second edition. For eosinophilic and allergic diseases, Dr. Weller has chaired an NIH/FDA panel related to the Churg-Strauss Syndrome, has authored chapters in major textbooks about eosinophilic diseases and been invited to lecture and lead seminars about eosinophilic diseases at national allergy, pulmonary, infectious diseases and hematology meetings.

Dr. Weller's teaching contributions have included lectures for HMS, HST and HSPH students on parasitic infections and eosinophilic diseases. He has consistently been a teacher of students, residents and fellows as a longstanding annual Attending Physician on the Medicine and Infectious Diseases services at the Beth Israel Deaconess Medical Center.
