Research Focus

My research program is aimed at testing the hypothesized trade-offs between growth/health and reproductive effort in an effort to answer how and why some males obtain and maintain high dominance status despite the potential costs. I use a multidisciplinary approach [e.g., behavioural ecology, endocrinology] to explore how individuals navigate the complexities of competition and cooperation associated with life in social groups. My recent research on white-faced capuchins in Costa Rica focused on the influence of dominance status on male co-resident relationships and endocrine response to female ovulation. My current and future research centres primarily on vervet monkeys at Lake Nabugabo in Uganda, where my long-term goal is to examine the hormonal and behavioural correlates influencing the emergence and maintenance of dominance in vervet monkeys. I also work in Kibale National Park, also in Uganda, where I examine the costs of group living in endangered red colobus, including the costs of dominance with respect to health [i.e., stress hormones, gastrointestinal parasites] in the context of male reproductive effort [i.e. testosterone].
