Dr. Lee’s research focuses on improving inclusivity of research data through addressing sampling and measurement issues in data collection with linguistic and racial minorities as well as hard-to-reach and older populations and cross-cultural survey methodology.
My current research interests include the implications of measurement error in auxiliary variables and survey paradata for survey estimation, selection bias in surveys, responsive/adaptive survey design, and interviewer effects in national studies, including those focused on older populations. I also have expertise in multilevel methods for clustered and longitudinal data.

Dr. Conrad studies respondent behavior in a survey context. He has investigated biases in judgments about the frequency of behaviors, the effect of automatic progress feedback on respondents’ willingness to continue filling out a questionnaire, and the decision to participate in a survey. He currently directs the University of Michigan’s Program in Survey Methodology.
Dr. Ryan’s research investigates individual and contextual influences on psychological well-being, physical health, and cognition as adults age. She has extensive experience developing, implementing and harmonizing over the life course new measures for studies of older adults.
