As a Visiting Fellow with TraCe, I study European rearmament policy from the perspective of legal accountability.

My research covers three broad areas. First, I am interested in arms trade and weapons transfer policy, in particular hu­man rights safeguards, export controls, corporate accounta­bility and due diligence. Second, I look at the gover­nance of global public goods through private law, including strategic litigation and supply chain resilience. Finally, I con­duct research on legal history, focusing on the intersection of ideas between public and private interna­tional law. During my fellowship at TraCe, I will study Euro­pean rearmament policies from the perspective of legal accountability.
