Emeritus Professor of Social Science Methodology at Utrecht University, the Netherlands.
Joops’ research interests include data quality in surveys and analysis models for complex data (often multilevel or clustered). His survey research focusses on nonresponse problems in surveys, data quality, and interviewer effects. His recent work includes problems concerning small sample sizes in multilevel analysis and strategies that can mitigate the problems that occur with small sample sizes, such as estimation accuracy and statistical power. Joop is former chair of the Dutch Organization for Methodological Research in the Social Sciences (NOSMO) and former president of the European Association of Methodology (EAM).
