Dr. Larry Clark

NWRC Director

Dr. Larry Clark became the Director of the NWRC in April 2008. Prior to this position, Dr. Clark served as the Center’s Assistant Director and was responsible for managing the NWRC and its field stations, setting internal policies and directives, and promoting collaboration among research programs. Dr. Clark began his career with APHIS in 1991 and during the past 17 years has been instrumental in establishing NWRC’s wildlife disease research capabilities. He has extensive research experience studying how animals perceive environmental chemicals. This has been useful in developing lures, repellents, and for understanding constraints on foraging ecology. He has also studied the use of biopharmaceuticals by wildlife and has experience in field and laboratory studies involving: physiological and behavioral temperature regulation and biophysical modeling; studying certain wildlife diseases and pathogens (E. coli, Salmonella, Campylobacter, Listeria, avian influenza and West Nile virus).
