Dr. Piotr Koc

Piotr Koc is a political scientist and sociologist, currently a postdoctoral researcher at the Department of Survey Design and Methodology at GESIS and an affiliated researcher at the Chair of Empirical Democracy Research, where he teaches seminars on quantitative methods and political sociology.

He obtained a Master’s degree in Political Science and Public Administration from the University of Konstanz and a PhD from the Institute of Philosophy and Sociology of the Polish Academy of Sciences, where he was part of the Research Group on Computational Social Science. He was also a research fellow at the Chair of Political Methodology in the Institute of Political Science at the University of Zurich.

Piotr’s main research focus is political methodology, particularly measurement issues. He has published on the measurement of political participation and the use of sparsity-inducing priors in dynamic latent variable models. His current research agenda revolves around dynamic group-level IRT models, involving extensive simulation studies and developing methods that use estimates from these models to evaluate the effects of policy interventions on public opinion.
