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, along with Dr. Linda Fedigan and Dr. Amanda Melin. 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. In 2022, we established the Santa Rosa Primate Conservation Fund, a non-profit dedicated to expanding knowledge, education, and conservation of wild primates in the endangered tropical dry forests of the Área de Conservación Guanacaste, Costa Rica.
