I have a Ph.D. in neuroscience and have been teaching and doing research for over 30 years. My research interests are primarily related to understanding how the brain responds to alterations in hormones, drugs, and aging. Of particular importance is the understanding of the mechanisms involved in short- and long-term memory. Although these studies are done in animals the goal is to understand the mechanisms underlying learning and memory in humans and to provide potential directions for therapy in patients with dementia. Related to this, is the attempt to understand potential sex differences and the effects of estrogen in learning and memory because women have a greater incidence of Alzheimer’s Disease than do men. The initial hormone studies led to an interest on the effects of Bisphenol A (BPA), a chemical used in plastics that has been shown to disrupt endocrine function, on both memory and brain structure. This research has been published in over 80 papers in peer referred journals.
