I came to Gettysburg after doing post-doctoral work at the University of Sydney and UCLA. I currently teach Psych 236 (Introduction to Brain and Behavior), Psych 237 (Psychopharmacology) and Psych 336 (Behavioral Neuroscience). My primary research interest is to identify neurobiological substrates of mammalian playfulness.
Why study play? And why study play in rats? Almost all mammals play. It doesn't seem to matter if you're a rat, dog, or human; there's something simply irresistible about a good bout of raucous social play. What makes mammals so playful? Are we genetically pre-programmed to have fun? Can early postnatal experiences influence how much we play? What kind of processing goes on in the brain that can make one youngster more, or less, playful than another? Using the young rat as a model system for studying rough-and-tumble play, work in my lab addresses questions such as these.
