About the Columbia-Presbyterian Medical Center Clinical Chronobiology Group



The Clinical Chronobiology Group, located at Columbia-Presbyterian Medical Center on the Upper West Side of Manhattan, focuses on environmental factors -- especially inadequate light exposure -- that may affect the operation of the internal biological clock and determine abnormal patterns of mood, sleep, energy, concentration and work productivity. Founded in 1984, we are the largest clinical research center in the U.S. dedicated to the study and treatment of winter depression (seasonal affective disorder, or SAD). We have developed and continue to study novel treatments as alternatives to drugs, under the support of the National Institute of Mental Health and New York State Office of Mental Health. Beyond SAD, we are also developing treatments for chronic depression in which oversleeping and overeating are associated problems, depression that occurs during pregnancy, jet-lag disturbance and insomnia.
