For many years I have done research on learning and cognition in animals, especially aspects of learning and memory that have a clear function in nature, as in foraging and spatial behavior. Recent research in the lab focussed on spatial learning in rats and memory processes in pigeons. Most recently I have been writing a second edition of my book, Cognition, Evolution, and Behavior, which was published by Oxford University Press in the fall of 2009. I am now working on a contribution to a new Oxford series of short texts on Fundamentals of Cognition, Fundamentals of Comparative Cognition. This will be published early in 2012.

I retired at the end of the 2008-09 academic year and am no longer supervising any new graduate or undergraduate students, post docs, or research assistants. However, I am always happy to talk about animal behavior and cognition and to advise students working in these areas.
