Personal profile
Area of Expertise
My area of expertise is in translational aging research. I am the Co-I of Health & Aging Brain among Latino Elders (HABLE) study (R01AG054073) and the Director of the Clinical and Outreach cores for this study. I have spent a great deal of time studying factors related to cognitive loss among Mexican-Americans with a specific emphasis on the link between depression and cognition. I have developed and cross-validated a depressive endophenotype (DepE) of cognitive aging across multiple national and international cohorts. This work has been translated into a proof of concept clinical trial (The DEMO trial). The DEMO trial utilizes a precision medicine approach to identify those individuals more likely to benefit from antidepressant treatment for prevention of memory loss and potentially Alzheimer’s disease.
