David Marcinek is a professor of radiology at the University of Washington School of Medicine, where he focused on the interaction between mitochondrial oxidative stress and energy metabolism in health and disease.

Marcinek research focuses on how mitochondria, the powerhouses of the cell, affect the ability of skeletal muscle to respond to stress. He will now test a novel regulatory mechanism underlying this interaction through the reversible oxidation of muscle proteins. His research could further define the mechanisms by which manipulation of mitochondrial function can rapidly improve health in the elderly.

He received a Ph.D. in Physiology from Stanford University studying muscle metabolism in endothermic and ectothermic fish species.
