The overarching goal of my research is to explain why biological sex is a risk factor for many diseases across the lifespan. Currently, I am examining how sex-steroid hormones act through cellular and molecular mechanisms to enhance memory formation and how those mechanisms may differ between the sexes to explain differences in the prevalence of Alzheimer’s disease.
