Lorenzo Moreno created szio evaluation convinced that the evidence obtained from impact evaluations of programs targeted to people left behind should be used for the social good. He received degrees (Ph.D. Demography; M.Sc., Economics and Statistics) from the London School of Economics and Political Science, and trained at Princeton University’s Office of Population Research. Lorenzo spent 25 years at Mathematica Policy Research, where he designed and directed complex impact evaluations of health care delivery and payment system reforms in the United States, and early childhood education and health initiatives in Latin America. He teaches a graduate course on impact evaluation tools at Princeton University’s Woodrow Wilson School of Public and International Affairs since 2010. Lorenzo has advised governments, multilateral organizations, foundations, and universities.  People have described him as creative, knowledgeable, experienced, insightful, thorough, and honest. He lives in Princeton, NJ.
