Research & Scholarship
My primary area of research is the behavioral ecology and conservation of non-human primates. My current research project examines the influence of forest fragmentation on the behavior, ecology, and population structure of wild mantled howler monkeys, white-faced capuchins, and Central American spider monkeys in Costa Rica.
I am also a Research Associate at the Denver Zoo in the Department of Animal Welfare and Research. Research projects focus on a range of animal species, including elephants, gibbons, hornbills, vipers, and mandrills.
Students can participate in my research by traveling to Costa Rica and studying monkeys in the wild. They can also conduct studies using data I have previously collected on a variety of primate species including hamadryas baboons, lemurs, mantled howler monkeys and capuchins.
Students can also conduct behavioral and animal welfare research with me at the Denver Zoo.
