Dr. Hews has been awarded major research grants from both the National Institutes of Health – studying hormone receptors in the brain of aggressive and nonaggressive lizards-- and the National Science Foundation --studying various aspects of evolution and physiology of animal communication signals. She has served as Editor to several major scientific journals and is an elected Fellow to the Animal Behavior society. She mentored several dozen undergraduate students in research and was the Major professor both Masters and Doctoral students in Biology. Recently retired, she is still engaged in research and also is working on a backlog of manuscripts.
