Research Interests

My main stream of research deals with decision making and rationality. I integrate concepts and techniques from operant and developmental psychology and comparative cognition research with normative theoretical models from optimal foraging theory and microeconomics. To see the thread of my research it is worth defining decision making. Decisions are not so much a subclass of behavior but a way to investigate it; all behavior can be described as choice. In practice, however, researchers deal with preferences between alternatives modeling how they are valued and how valuation drives choices. I use optimality and learning theory to deal with valuation, and empirically supported algorithms to translate valuation into choice. I usually endeavor to develop a model of the causative process under investigation, if possible in mathematical language, and then test it by experiment.
