Research Interests:

My research aims to understand how environmental conditions (e.g. pollution) influence reproductive development, physiology, and behavior, and to devise ways to reduce the incidence of reproductive abnormalities in wildlife and humans. I use an integrative systems approach that combines field and laboratory methods to investigate the effects of endocrine disrupting chemicals (EDCs) across multiple levels of biological organization—from molecules to populations. I ask questions that are conceptually motivated so that my work is general and informative to diverse scientific fields including development, physiology, evolution, ecology, and conservation.
