- I received my undergraduate and graduate degrees from the Biological Wing of the Department of Anthropology at Harvard University. After finishing my undergraduate work in 1996, I spent a year living in Indonesian Borneo managing Cheryl Knott's long-term orangutan research project and working for National Geographic. I returned to Harvard's Anthropology Department in 1997 to do my PhD with Mark Leighton and Richard Wrangham. While in graduate school I did fieldwork on apes in Uganda and the Democratic Republic of Congo before returning to Kalimantan to study gibbons and leaf monkeys. During my fieldwork I became interested in botany and plant ecology, and upon completion of my PhD in 2004 I did a two-year post doc at The Arnold Arboretum in the Department of Organismic and Evolutionary Biology at Harvard. I joined the UC Davis faculty in the fall of 2006.
In addition to serving on the faculty in the Department of Anthropology, I am a member of the Graduate Group in Ecology, where I currently serve as chair of the Conservation Ecology Area of Emphasis. I am also a faculty member in the Animal Behavior Graduate Group and an affiliate of the John Muir Institute of the Environment.
I am interested in the study of vertebrate evolutionary ecology and conservation, particularly in the tropics. I am currently studying how ecological factors limit primate density and how habitat quality influences the viability and demographic structure of populations, the composition of social groups, and the behavior and fitness of individuals. Most of this work uses Southeast Asian primates, particularly gibbons, leaf monkeys, and orangutans, as focal taxa. My work also seeks to understand how temporal variation in the quality and quantity of food resources affects the physiology, reproductive rates, and grouping patterns of primate species with different dietary adaptations and life histories. I maintain active interest in four additional areas: tropical forest ecology (focusing on phenology of trees and lianas and the co-evolution of vertebrate frugivores and rainforest plants), community ecology (focusing on the relative roles of neutral (or neutral-like) mechanisms and niche processes in structuring communities of tropical vertebrates), vertebrate population survey techniques, and the theory and applications of conservation biology, particularly as they relate to endangered primates and their tropical forest habitats. My main research site is Gunung Palung National Park, located in West Kalimantan, Indonesia. I am also involved in orangutan and forest conservation initiatives in collaboration with both governmental and non-governmental stakeholders at several sites in Indonesia.
