Research Professor, ISR, Survey Research Center, Survey Methodology and JPSM, University of Maryland
James Wagner is an Research Professor in the Survey and Data Science Program. He received his PhD from the Michigan Program in Survey and Data Science in 2008. He has worked on surveys for over 20 years and has extensive experience with sample design. He currently serves as the Chief Mathematical Statistician on the National Survey of Family Growth Continuous 2011-2019. In addition to sample design, Wagner’s research interests include adaptive survey design to address potential nonresponse biases and indicators of survey data quality.
