J. Larry Jameson, M.D., Ph.D., became Executive Vice President of the University of Pennsylvania for the Health System and Dean of the Raymond and Ruth Perelman School of Medicine on July 1, 2011. Together, the two entities make up Penn Medicine, a more than $6.5 billion enterprise dedicated to excellence in the related missions of medical education, biomedical research, and patient care.

Founded in 1765 as the Colonies’ first medical school, the Perelman School of Medicine is now home to over 2,000 full-time faculty members and more than 3,500 students, trainees, residents, and fellows. The School receives nearly $750 million in sponsored program research. The University of Pennsylvania Health System includes multiple nationally ranked hospitals, a clinical network that includes primary care, a faculty practice plan, home care, hospice, nursing homes, and three multispecialty satellite facilities.

Before coming to Penn Medicine, Dr. Jameson was Dean of the Feinberg School of Medicine and Vice President of Medical Affairs at Northwestern University, positions he held since 2007. He joined Northwestern University Medical School in 1993 as chief of the Division of Endocrinology, Metabolism, and Molecular Medicine, a position he held for seven years. In 2000, he was named Irving S. Cutter Professor of Medicine and chair of the Department of Medicine.

Dr. Jameson received his medical degree with honors and a doctoral degree in biochemistry from the University of North Carolina in 1981. He completed clinical training in internal medicine and endocrinology at Massachusetts General Hospital in Boston. Before leaving for Northwestern University, he rose through the ranks at Harvard Medical School to become an associate professor of medicine and chief of the Thyroid Unit at Massachusetts General Hospital.

A prolific physician-scientist and writer, Dr. Jameson has been a pioneer in molecular medicine in the field of endocrinology. His research has focused on the genetic basis of hormonal disorders and he is the author of more than 350 scientific articles and chapters. His work has been published in leading peer-reviewed journals, including The New England Journal of Medicine, Nature Genetics, Science, and the Journal of Clinical Investigation. He is an editor of Harrison’s Principles of Internal Medicine, the most widely used medical text worldwide, and co-editor of Jameson and DeGroot’s Endocrinology, now in its 7th edition.

Among his many professional distinctions and honors, Dr. Jameson was elected to the American Academy of Arts and Sciences, one of the oldest learned societies in academia, and the National Academy of Medicine, established to recognize professional achievement in the health sciences. He has been elected to the American Society of Clinical Investigation and the Association of American Physicians, and as a Master of the American College of Physicians. He has served as president of the Endocrine Society and the Association of American Physicians. He has served as a member of the medical advisory board of the Howard Hughes Medical Institute and as a Director of the American Board of Internal Medicine.

Dr. Jameson has received many distinguished awards, including the Van Meter Award from the American Thyroid Association and the Sheen Award from the American College of Surgeons. The Endocrine Society has honored him twice: with the Ernst Oppenheimer Award, presented to a young investigator in recognition of meritorious accomplishments in basic or clinical endocrinology, and the Fred Conrad Koch Award, considered the highest honor bestowed by the Society in recognition of exceptional contributions to the field. From the American College of Physicians, Dr. Jameson received the Award for Outstanding Science and John Phillips Award for outstanding work in clinical medicine. As a visiting lecturer, he has been invited to present at leading institutions around the world.
