My primary research interests focus on the relationship between foraging theory, sexual selection, and lifetime fitness. I concentrate on the crab spider Misumena vatia, a sit-and-wait predator on flowers, for this work, but have also used birds, bumblebees, and other insects. My present book, "Predator Upon a Flower", synthesizes these long-term efforts. A more recent interest focuses on four-trophic-level systems and the role that indirect effects may play in structuring communities.
I am a behavioral ecologist and am especially interested in 1) host-parasitoid relationships and 2) foraging behavior and and how it relates to life history strategies that affect lifetime fitness. Recently I have concentrated this work on cognitive aspects that address the roles of innate and learned traits, and how their contributions change over a lifetime. I have published three books that chronicle my research career. I commenced my career at the University of Maryland and came to Brown in 1979 as the Hermon Carey Bumpus Professor of Biology, officially retiring in 2005, but remaining active in my research field, mentoring undergraduate research, and offering a reduced load of courses. I was chairman of the group that is now the Department of Ecology and Evolutionary Biology for most of my tenure at Brown.
