The Spotlight Series has now expanded to audio! Each Spotlight shows the breadth and scope of research interests and expertise at the Population Studies Center and the Population Aging Research Center at Penn. In this installment of the series I had the pleasure of interviewing Jere R. Behrman and Irma T. Elo. Jere Behrman is the William R. Kenan Jr. Professor of Economics and Professor of Sociology. Irma Elo is the Associate Director of the Population Aging Research Center. She is also the Chair of Sociology here at Penn. In this Spotlight I spoke with Jere and Irma about a longitudinal data aging project in Chile that aims to asses cognition in elderly populations. This global and collaborative project is a fascinating example of why it takes a village to do demographic and aging research. Enjoy!
