Overview of the DeWitt Lab:

Our environmental developmental neuroimmunotoxicology research program explores relationships between biological organisms and their developmental responses after exposure to environmental toxicants. Early life exposure to a variety of agents impacts the immune, nervous, and endocrine systems, resulting in altered development that may present as diseases or disorders in childhood. We are particularly interested in how impacts to the immune system lead to downstream effects on the nervous system. Please visit our lab-specific web page for more detailed information about our research program.
