My primary research interests focus on how emotional states influence cognitive processes such as facial recognition. My past research has shown how positive emotional states can improve cross-racial identification. I have taught a wide variety of courses, but my specialty is in teaching Social Psychology, Cognitive Psychology, and Social Cognition. I also have a strong interest in Evolutionary Psychology, because evolutionary perspectives allow us to explain all scientific disciplines under a single framework.
