I am a primate behavioral ecologist with a research focus on male reproductive strategies. I have studied a number of different primate species throughout my career, though the bulk of my research focuses on a population of white-faced capuchin monkeys (Cebus imitator) in Santa Rosa National Park, Costa Rica.
The Santa Rosa primate project began in 1983 and is one of the longest-running research projects focusing on platyrrhine primates. I began my research at the site in 1997 and in 2004 I became project co-director. Via my collaborations with the Santa Rosa research team, graduate student, and a number of experts in the areas of primate genetics, endocrinology, and sensory ecology, my research makes use of long-term demographic, life history, behavioral, and biological data to examine male reproductive strategies throughout the life course. Since beginning my studies in Santa Rosa, I have also been intimately involved in the on-going study of the long-term population trends of the capuchin and howler monkeys in the park. Our team has been conducting park-wide censuses of these two primates since 1983, in order to track the effects of forest protection, forest regeneration, and climate change on primate populations.
