I am an Associate Professor in the Department of Anthropology at the University of Wisconsin-Madison, United States. I also hold a Senior Honorary Research Fellow position in the School of Physiology at the University of the Witwatersrand, South Africa, and affiliate faculty positions in the Department of Integrative Biology and the Center for African Studies at UW-Madison. My research combines behavioral, ecological, and physiological data to investigate individual, population and species differences in fitness, particularly in relation to environmental variability and the consequences of sociability. My primary research focuses on chacma baboons and vervet monkeys in South Africa. These are ideal model organisms for my research because they are obligatorily social, experience a wide temperature range in extreme environments, and manifest a range of specialized social and thermoregulatory adaptations. I welcome enquiries from prospective graduate students and all those interested in gaining field experience.
