His current research interests include the implications of measurement error in auxiliary variables and survey paradata for survey estimation, selection bias in surveys, responsive and adaptive survey design, interviewer effects, the analysis of complex sample survey data, and multilevel regression models for clustered and longitudinal data. He is the lead author of a book comparing different statistical software packages in terms of their mixed-effects modeling procedures (Linear Mixed Models: A Practical Guide using Statistical Software, Third Edition, Chapman Hall/CRC Press, 2022), and of a second book entitled Applied Survey Data Analysis (with Steven Heeringa and Pat Berglund), the third edition of which was published by Chapman Hall in April of 2025.
