Evolutionary psychology is the application of evolutionary principles to the understanding of human behavior; essentially, it is "human sociobiology." I feel strongly that a thorough understanding of human behavior must be based on a solid evolutionary framework, and accordingly, I've been especially concerned with research into the following: inclusive fitness theory and its implications for altruism and cooperation, as well as intolerance and racism; male-female differences in sexual behavior and inclinations; parenting strategies including the conundrum of parent-offspring conflict; the underlying causes of interpersonal and interstate violence; and the application of game theory (including Evolutionarily Stable Strategies) to interpersonal interactions.
