Zach is a senior statistician with NORC at the University of Chicago, where he works on sample design, estimation, and data analysis for government and public interest surveys.
Zach contributes to weighting, total survey error analysis, small area estimation, imputation, and adaptive design for such surveys as the National Immunization Survey, the General Social Survey, the Survey of Doctorate Recipients, and Jewish community studies. Additionally, Zach’s expertise includes analyzing administrative data quality and combining data sources for evidence-building, topics on which he has published research in the Statistical Journal of the International Association of Official Statistics and the International Journal of Population Data Science. He has led development of tools to support researchers with evaluating data quality of non-survey data sources.
Zach further serves as an adjunct faculty member with Northwestern University's School of Professional Studies, teaching in the Public Policy and Administration program. He serves on the American Association for Public Opinion Research’s Standards Committee.
