James Wagner

James Wagner, Ph.D. is a Research Professor at the University of Michigan’s Survey Research Center (UM-SRC). His research is in the area of survey nonresponse and methods for addressing it during data collection. He has co-authored a book on adaptive survey design — which is a set of methods that aims to optimize the recruitment ...

Henning Silber

My research focuses on quantitative social research methodology, and I use machine learning to identify bias in social science data, especially due to measurement and nonresponse error, and to process unstructured data. I also use LLMs for the classification of text data, and explore strategies to use AI in questionnaire design. I first started to ...

Sunghee Lee

My research focuses on issues in data collection with hard-to-reach populations. In particular, she examines 1) nontraditional sampling approaches for minority or stigmatized populations and their statistical properties and 2) measurement error and comparability issues for racial, ethnic and linguistic minorities, which also have implications for cross-cultural research/survey methodology. Most recently, my research has been ...

Yajuan Si

My research lies in cutting-edge methodology development in streams of Bayesian statistics, complex survey inference, missing data imputation, causal inference, and data confidentiality protection. I have extensive collaboration experiences with health services researchers and epidemiologists to improve healthcare and public health practice, and have been providing statistical support to solve sampling and analysis issues on ...

Z. Tuba Suzer-Gurtekin

Z. Tuba Suzer Gurtekin is an Assistant Research Scientist at the University of Michigan’s Institute for Social Research. Her research includes managing monthly surveys of consumer attitudes, expectations and behavior. Her published research focuses on methods to quantify nonresponse and measurement survey errors in probability and nonprobability sample surveys, and mixed-mode survey design and inference. ...

Brady West

My current research interests include the implications of measurement error in auxiliary variables and survey paradata for survey estimation, survey nonresponse, interviewer variance, and multilevel regression models for clustered and longitudinal data. I also conduct research in statistical software.
