Evolutionary and ecological aspects of animal social psychology and behavior; insect behavioral ecology; human behavioral ecology and evolutionary psychology; evolutionary methodology. Specific research interests include:

• The evolution of human social psychology and behavior.
• Fluctuating asymmetry and sexual selection.
• Field study of people in a remote Caribbean village.
• The evolution of female sexuality.
• Evolutionary ecology of insects of the order Mecoptera.

My research focuses on the evolution of social and sexual behavior in animal taxa ranging from spiders and insects to humans. My work with humans is on a heuristic, theoretical level, although several of my students do empirical research on Homo sapiens. I am interested in developing evolutionarily principled conceptual models of human intrapsychic organization. I am especially interested in the adaptive function of conscious experience and the relationship between phenomenal consciousness and unconscious information processing.

In my work with animals, I focus on interdisciplinary studies of invertebrates designed to reveal the information content of sexual signals and thus the adaptive significance of decision rules used to choose mates and determine which mates contribute genetically to offspring.
