Isaac Maddow-Zimet

Portrait of Isaac Maddow-Zimet

Isaac Maddow-Zimet joined the Guttmacher Institute in 2010. He leads the Institute’s efforts to identify new approaches for leveraging, generating, integrating and visualizing data, and is the co-lead of the Research Division’s Reproducibility Core, a team devoted to improving the computational reproducibility and transparency of Guttmacher’s research. His main areas of research have included abortion measurement, estimation of pregnancy statistics in the United States, pregnancy desires, and adolescent sexual health and behavior, and he has published articles in Demography, JAMA Pediatrics, Population Research and Policy Review and the Journal of Adolescent Health, among others. He received his BA in sociology and Iberian studies from Wesleyan University, and his MS in applied statistics from New York University.
