RESEARCH INTERESTS

We investigate reproduction and development and are particularly interested in: 1) social and neuroendocrine regulation of alternative reproductive phenotypes and sex differences; 2) mechanisms and evolution of maternal effects; 3) developmental plasticity and life histories; and 4) epigenetic mechanisms of maternal effects. Our studies focus on long- and short-term modifications of offspring development and phenotype by maternal hormones. We are also interested in adult phenotypic plasticity, stress physiology, endocrine disruption, and sexual differentiation of brain and behavior. Our main study systems are birds.
