Collapse Overview 
Collapse overview
Dr. Frank A.J.L. Scheer is Associate Professor of Medicine at Harvard Medical School and the Director of the Medical Chronobiology Program at Brigham and Women’s Hospital.

Dr. Scheer is primarily interested in medical chronobiology, including the underlying physiological mechanisms and therapeutic strategies. His work focuses on circadian and behavioral influences (including the sleep/wake cycle) on cardiovascular, pulmonary, and metabolic regulation and disease. Furthermore, he is interested in fundamental properties of the human circadian timing system, including effects of light and melatonin.

Dr. Scheer received his PhD in Neuroscience at the Netherlands Institute for Brain Research in Amsterdam, The Netherlands, and his postdoctoral training in the laboratories of Drs. Charles A. Czeisler and Steven A. Shea.
