My research focuses on behavioral endocrinology, the dynamic and complex interactions among hormones, brain, and behavior. I am especially interested in the control of endocrine function and fertility by the social environment. Such social influences are particularly pronounced in cooperative breeders, species in which a single, behaviorally dominant female breeds in each social group and other groupmates provide "alloparental care" for her offspring. Behaviorally subordinate females typically undergo physiological and/or behavioral suppression of reproduction in response to social cues and may become completely infertile as a consequence of their subordinate status.
I am also interested in the interactions between psychosocial stress and reproduction. Much attention has focused on the potential role of stress in inhibiting fertility. In reality, however, the relationship between stress-related physiology and reproductive function is more nuanced, highly complex, and bi-directional. Thus, my research has focused on the cross-talk between stress-related hormones and the reproductive system, especially within the context of critical social influences. This work has broad relevance to vertebrate reproductive and behavioral biology, as well as numerous clinical applications in humans.
My current and recent research includes studies of cooperatively breeding common marmoset monkeys (based at the National Primate Research Center at the University of Wisconsin – Madison) and gerbils (at UC Riverside). Topics include:
• Behavioral determinants of reproductive suppression
• Neuroendocrine mechanisms of reproductive suppression
• Mechanisms of social suppression of the hypothalamic-pituitary-adrenal axis
• Social and hormonal influences on parental behavior
• Infanticide as a female reproductive strategy
I participate in the Physiology graduate track within the Department of Biology's Evolution, Ecology, and Organismal Biology Graduate Program, as well as the interdepartmental Neuroscience and Biomedical Sciences Graduate Program.
