Dr. Cohen’s research interests center around the genetics and physiology of osmoregulation (water balance). His group conducts studies at the cellular level, in animal models, and in human cohorts. Dr. Cohen directs the Genetics of Water Balance Consortium, a global network of major cohorts investigating genetic associations in water balance-relevant phenotypes. He also serves as local site investigator for the Portland site of the VA’s Million Veteran Program – a national voluntary research program to study how genes affect Veterans’ health. Local recruitment for this effort recently topped 11,000 enrolled Veterans.
