Biography

The broad goal of Dr. Daniel’s research is to understand mechanisms by which estrogens and androgens impact areas of the brain important for cognition. Current work in the lab is focused on the impact of these hormones on the brain and cognition across the lifespan, from early in development during which they help organize mammalian brains as male or female to later in life during which changes in their levels impact the aging brain. Research is conducted in rodent models and experimental approaches used in the lab include behavioral analyses as well as biochemical and molecular assays.
