We’re delighted to welcome Siobhan Steel as a Fellow with CEPA’s Transatlantic Defense and Security Program.

Siobhan is also the Council on Foreign Relations Robert A. Belfer International Affairs Fellow in European Security, where she studies Europe’s growing emphasis on sovereign capability and what it means for interoperability and transatlantic security cooperation. She served at the US Department of Homeland Security from 2017 to 2025, most recently as Deputy Director for Latin America and the Caribbean in the Office of International Affairs, and earlier led an intelligence team focused on transnational organized crime. In the private sector, she was Chief of Staff at BMNT Ltd, which helps bring commercial innovation into UK defense.

We look forward to Siobhan’s contributions to CEPA’s work on transatlantic security.
