Proximate and ultimate influences on social behavior: including individual variation in genes, brain, and behavior; monogamy and social attachment; alternative reproductive tactics; parental care; early life social influence on development; social and spatial memory; mate choice; animal communication; reproductive decision-making

Current Research Interest

Individual differences in the neurobiology of social behavior and how that influences reproductive decision-making; the impact of early life social experiences on the developmental trajectories of genetic, epigenetic, molecular, and neuroendocrine functioning in the brain, and impacts on cognition and behavior during development and adulthood; the influence of social context and cognition (socio-spatial memory) on adult reproductive decisions and the forms of alternative reproductive tactics that animals select
