Dr Thomas Conzelmann, Prof. (T.)
Research profile
My research focuses on the exertion of leverage in international and EU politics through various Instruments, including soft instruments such as peer reviews among states , and hard instruments such as economic coercion measures. I also research the ‘geo-economic turn’ in global affairs and the corresponding policies of the EU. My research is published, among others, in Cooperation and Conflict, Journal of Common Market Studies, Journal of European Integration, and Regulation and Governance.
Research projects
The softening and hardening of borders (LIMES) (2020-2025)
I am coordinator (with Sophie Vanhoonacker) of a doctoral network of 13 PhD researchers at UM, funded by the European Commission through its COFUND programme.
Beyond the carrot and the stick: What makes peer reviews among states authoritative instruments of global governance? (2013-2019)
The project focused on the authority of peer reviewing procedures among states as an increasingly widely used, yet poorly understood instrument of global governance. It looked at peer reviews in different international organisations (The UN family, the WTO, the OECD and the Council of Europe) and in different policy areas (anti-corruption, human rights, economic and trade policies). http://peer-reviews.info
