Thomas Siedler is Professor in Economics, in particular Economic Policy at the Universität Potsdam. Thomas received his PhD in Economics at the University of Essex (UK) in 2007. His general research interests are labour economics, health economics, family economics, and intergenerational mobility.

He developed the e-learning website www.mcempirics.com. mcEmpirics comprises more than 800 introductory econometric questions, answers to those questions, and references to manuals. It gives undergraduate students an opportunity to assess their knowledge of introductory econometrics and refresh their skills by playing quizzes. Teachers and lecturers at universities with a mcEmpirics campus license can easily create their own courses and online tests, without any correction time needed.

Thomas published, for example, in the American Economic Journal: Economic Policy, Economic Journal, Journal of Public Economics, Journal of Human Resources, Journal of Health Economics, Demography, European Economic Review, Economica, and the Journal of the Royal Statistical Society: Series A.

He joined IZA as a Research Affiliate in October 2005 and became a Research Fellow in May 2008.
