John G. Fleagle is a primatologist whose research combines field studies and functional morphological analysis. He is interested in the adaptive radiation of primates during the last 56 million years. He has conducted paleobiological research in Egypt, Argentina, and Ethiopia and has studied living primates in Malaysia, Surinam, Brazil and Madagascar. Dr. Fleagle is a MacArthur Fellow.Andrea Baden is a primatologist whose research combines traditional field work with laboratory (genetic, hormone, nutrition) analyses to answer broad evolutionary questions about primate social and reproductive strategies. Her research focuses primarily on Malagasy strepsirrhines, including one of the only long-term studies of wild ruffed lemurs.Chris Gilbert is a primate morphologist and paleontologist broadly interested in primate evolution over the last 66 million years, with an emphasis on craniodental anatomy and phylogenetic systematics. He has conducted paleontological fieldwork in North America, Egypt, Kenya, South Africa, and India, as well as behavioral research on extant primates in Thailand and the Duke Lemur Center.
