Ecology, Evolution and Behavior


Research Interests

Experimental behavioral ecology, foraging behavior; animal decision-making; evolutionary approaches to animal cognition; learning and memory as adaptations

Statement

My research blends mathematical and experimental analyses to address a range of issues in behavioral ecology, especially feeding behavior. My experiments use psychological techniques, and this brings the conceptual approach of behavioral ecology into contact with the more mechanistic approach of psychology. Current interests in my laboratory are 1) combining evolutionary and mechanistic analyses of behavior using animal impulsivity as a worked example; 2) evolutionary models of "cognitive" phenomena, e.g. learning, memory and decision-making; 3) Experimental games, including experimental analysis of putatively cooperative games such as the Iterated Prisoner's Dilemma and related ideas.
