Alexander Wenz

Postdoctoral Researcher in
Statistics and Methodology

University of Mannheim

Welcome to my website.

I’m a Postdoctoral Researcher at the Professorship for Statistics and Methodology at the School of Social Sciences at the University of Mannheim.

I’m also affiliated with the Mannheim Centre for European Social Research (MZES), the International Program in Survey and Data Science (IPSDS), the Collaborative Research Center SFB 884 Political Economy of Reforms at the University of Mannheim, and the Institute for Social and Economic Research (ISER) at the University of Essex. I currently serve as Committee Member of the European Survey Research Association (ESRA).

I’m interested in topics related to survey methodology, social data science, and digital sociology. In my current research, I examine the data quality of novel data collection methods used in empirical social research, with a focus on (mobile) web surveys, passive measurement with smartphone apps and wearable sensors, and linkage of survey and social media data.
