New Researchers Join TraCe

TraCe welcomes three new Associate Fellows

In the summer of 2025, three new Associate Fellows have joined the TraCe re­search center: Ayşe-Martina Böhringer, Markus Bayer, and Frederik Schissler.

Ayşe-Martina Böhringer is based at the Chair of Public Law and International Law at Justus Liebig University Giessen, where she is currently preparing her habilitation. Her research in inter­national law focuses on legal questions of collective security. As part of TraCe, she examines the two areas ius ad bellum (right to go to war) and ius in bello (the right to wage war).

Markus Bayer is an Associate Fellow at PRIF’s Research Depart­ment Local Peace Orders, where he leads the project “Echoes of the Past”. His research is situated at the intersection of political vio­lence, collective memory, and its socie­tal impacts. In the context of TraCe, he investi­gates know­ledge within Ger­many regarding its colonial history in Namibia and how this has been pro­cessed in public discourse.

Frederik Schissler joins from PRIF, where his research fo­cuses on the trend toward inter­nationalization of intra­state conflicts. Data on the develop­ment of intrastate vio­lence paints a clear picture, particularly since the early 2010s: intra­state conflicts are increasing­ly inter­nationalized by the inter­vention of exter­nal actors. As part of TraCe, Frederik Schissler examines forms of external support in civil wars and analyzes the broader trend toward inter­nationalization from a net­work pers­pective at the macro level.
