Reproduction, developmental plasticity, maternal effects, epigenetic mechanisms, hormones and behavior
We investigate reproduction and development and are particularly interested in: 1) social and neuroendocrine regulation of alternative male reproductive phenotypes; 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, endocrine disruption, and sexual differentiation of brain and behavior. Our main study systems are birds.
