I am a senior researcher in the team Survey Data Augmentation at GESIS - Leibniz Institute for the Social Sciences (Department Survey Data Curation) in Cologne, Germany, and (co-)lead the team Research Data & Methods at the Center for Advanced Internet Studies (CAIS) in Bochum, Germany.
My research focuses on the uses and effects of digital media, data linking (esp. linking surveys with digital trace data), data management, and open science. I frequently give workshops on topics related to quantitative and computational research methods and the statistical programming language
R, and have also taught classes in psychology and communication at both the graduate and undergraduate level.
