Research Interests

Dr. Bell’s research is focused on the effects of a chronic and ubiquitous environmental contaminant, polychlorinated biphenyls (PCBs). PCBs are a model endocrine disrupting chemical, and are known to independently affect brain function, hormone actions, and immune processes. As such, the lab is interested in understanding how PCBs affect interactions between the neural, endocrine, and immune systems during development, and their long-term consequences on brain and behavior. They use molecular and behavioral techniques to study this in a rat model.
