A new $2.5 million grant from the National Institutes of Health is enabling Vanderbilt University chemist Renã A.S. Robinson to expand her research on racial disparities in Alzheimer’s and other diseases. Robinson, an associate professor of chemistry and Dorothy J. Wingfield Phillips Chancellor Faculty Fellow, is the co-principal investigator on the R01 grant, which is designed to develop and test recruiting materials aimed at encouraging older African Americans to participate in Alzheimer’s research.
