As a PhD student he was employed as a research associate at the Department of Economics, at   the chair Empirical Economic Research and Econometrics at the RWTH Aachen University and at the University of Bay-reuth. He taught several consecutive courses on empirical methods and quantification in economics. He also gained extensive independent teaching experience as an external lecturer with a specialization on quantitative and empirical methods at the Frankfurt School of Finance & Management, the FernUniversität in Hagen, and within the accredited masters programs at the Haus der Technik e.V.

His dissertation consists of essays on international trade and migration research with a structural and quantitative focus.
