Carl Müller-Crepon's research focuses on state building and its effects on local development and conflict, in particular in Africa. His most recent work explores the reciprocal relationship between ethnic geographies and (sub-)national political borders in Africa and Europe since the 19th century. Until August 2022, Carl was a Lecturer at the Department of Politics and International Relations at the University of Oxford. Previously, he was a PostDoc at the International Conflict Research Group at ETH Zurich and a visiting scholar at Harvard University’s Institute for Quantitative Social Science. Throughout, Carl innovates and uses computational methods to collect and analyse large, mostly geospatial datasets. His work has been published in International Organization, the British Journal of Political Science, the Journal of Peace Research, the Journal of Conflict Resolution, and Political Science Research and Methods.
