Biography
Dr. Shaw is a graduate of Harvard College who completed his M.D. training at Harvard Medical School and his Ph.D. in the laboratory of Philip Leder. After completing his clinical training in Internal Medicine and Infectious Diseases at Massachusetts General Hospital, he was a postdoctoral fellow in the laboratory of Fred Alt. Dr. Shaw joined the faculty at Yale in 2001, and is currently Professor of Medicine in the Section of Infectious Diseases. His research focuses on the immunology of aging, and his laboratory has interests in age-associated alterations in innate immune function and vaccine response in humans, as well as circadian regulation of immune response and mechanisms of inflammatory dysregulation in medication-associated treatment of opioid use disorder. He was a Howard Hughes Postdoctoral Physician Research Fellow, Brookdale National Fellow, and T. Franklin Williams Scholar, and he is a Fellow of the Infectious Disease Society of America and member of the Interurban Clinical Club.

Overview
Albert C. Shaw, MD, PhD, is an infectious diseases specialist who provides care for individuals with a variety of infections, including those that affect older adults. He focuses on how age-related changes in the body’s defenses can make people more vulnerable to infection and immune system complications.
As a professor of medicine at Yale School of Medicine, Dr. Shaw studies the ways in which the immune system’s first line of defense, called the innate immune system, changes with age. This includes investigating how these shifts might reduce vaccine effectiveness and contribute to ongoing, low-grade inflammation that can harm overall health. He also examines how circadian rhythms—biological processes that follow a 24-hour cycle—may regulate immune responses, as well as how certain treatments for opioid use disorder might influence inflammation.
Dr. Shaw earned his medical degree from Harvard Medical School and completed a doctorate at Harvard University. He then pursued an internal medicine residency and an infectious diseases fellowship at Massachusetts General Hospital.
