Tulane University has received a $6.7 million grant from the National Institutes of Health to study the lasting health, demographic and socioeconomic impacts of Hurricane Katrina on the New Orleans region. The five-year grant will establish the Tulane Center for Studies on Displaced Populations, the goal of which is to gauge how different populations have recovered or faltered more than 10 years after the storm, according to a Tulane news release.
