Survey Methodology | Statistics | Data Science


Hi – I’m Ruben, postdoctoral researcher at the University of Mannheim (see also here) in social science quantitative research methods. I’m especially interested in all topics related to survey research, big data in the social sciences, machine learning and causal inference.

I spent the last three years in the Institute for Employment Research (IAB)’s graduate program where I wrote my dissertation on behavioral consequences of repeated measurements in social science surveys using methods of causal inference and machine learning.

My current research projects involve using digital trace data (online and mobile web activity) for social research, machine learning in survey research (e.g., for response propensity models) and the various ways how participating in a survey can influence respondents‘ future behavior.

My work on behavioral changes due to repeated survey participation was recently published in the Journal of the Royal Statistical Society, Series A: Statistics in Society. A second paper on changes in reporting over the waves of a panel survey has appeared in Journal of Survey Statistics and Methodology.

If you want to know more about me, my work or if you are interested in collaborating,  send me an email or contact me on LinkedIn or Twitter.
