Research Interests:

• The role of steroid hormones in brain development and cognitive behavior
• Interactions between environmental factors, the endocrine system and neural development
• Effects of endocrine disruptors on the mesocortical dopamine system
• Effects of adolescent blue light exposure on brain development and cognition 

I am currently involved in several lines of research in the field of developmental neuroendocrinology. In one project, we are examining the synergistic effects of maternal infection and common endocrine-disrupting toxicants on development of the prefrontal cortex and executive functions in perinatally exposed offspring. Additionally, we are conducting another series of experiments aimed at assessing the effects of various agricultural practices on neurodevelopment and cognitive maturation. Third, we are interested in the developmental ontogeny of dopaminergic cells of the midbrain during adolescence, with a particular focus on how pubertal hormones regulate dopamine cell number.  Lastly, we are conducting a study to assess the effects of nightly blue light exposure throughout adolescence on development of the prefrontal cortex, hippocampus and learning/memory ability.
