Research Interests

My research program is focused on investigating the genetic, molecular, cellular, and behavioral contributions underlying the divergence of neurodegenerative disorders including Alzheimer’s disease from healthy Aging. My laboratory is a critical component of several NIA-funded multi-institutional Open Science consortia including MODEL-AD, TREAT-AD, and MARMO-AD. Building on my drug discovery expertise and 18-year tenure in the pharmaceutical industry, a major goal of my research is to identify tractable targets as therapeutic interventions by the development and comprehensive phenotypic characterization of genetic animal models including mice and marmosets in order to understand divergence of disease progression from normal healthy aging and as model systems to evaluate potential therapeutic interventions. We are also focused on using pharmacological and genetic tools coupled with multi-omics approaches to interrogate biological targets that may be drivers of the divergence of normal healthy aging towards pathogenesis and progression of neurodegeneration, dementia, and cognitive decline.
