David EdwardsCharles Howard Candler Professor of Behavioral Neuroscience


Dr. Edwards received his B.A. in Psychology from Reed College in 1964. He completed his Ph.D. in Biological Sciences at the University of California, Irvine in the summer of 1968, and joined the Emory faculty in the fall that same year.

Hormonal correlates of competition and performance, ability, and status in intercollegiate athletics and other settings

Current Projects

Field studies having to do with the effects of athletic competition on levels of cortisol and testosterone and laboratory studies relating individual differences in hormone levels to individual and sex differences in human performance.
