About David J. Earnest

David Earnest, PhD, is a professor in the Department of Neuroscience and Experimental Therapeutics at the Texas A&M School of Medicine. His research interests are focused on neuroscience and biological clocks that regulate circadian rhythms in sleep and other body processes. His research uses multidisciplinary approaches to study how pathologies and environmental disturbances in the regulation of circadian rhythms are linked to variety of human health disorders including obesity and diabetes, increased cancer risk, cardiovascular disease and stroke, Alzheimer's Disease, Fetal Alcohol Syndrome (FAS), sleep-wake cycle disturbances and depression, and implications of circadian disruption and shift work in human health.

Dr. Earnest is also an executive member of the Texas A&M University Center for Biological Clocks Research.

Dr. Earnest received his Bachelor of Science in 1976 from the University of Michigan, Master of Science in 1979 from Northwestern University and Doctor of Philosophy/doctorate in Neurobiology from Northwestern University in 1984. He also was a NIMH Postdoctoral Fellow at University of Rochester School of Medicine from 1984-87.
