Areas of Expertise: Cognitive Psychology, Evolutionary Psychology, Language Acquisition, and Animal Behavior
Program/Courses Taught: PSYC100, PSYC200, PSYC215, PSYC250, BIOL115
My research investigates language-related perceptual and cognitive abilities, including speech perception, statistical and rule-like learning, and other critical aspects of language learning. My main interest is the evolution of these capabilities, and therefore I take a comparative research approach by investigating the language-related abilities of nonhuman primates.
