The Center for Climate and Security (CCS) is pleased to announce a new round of hires across its programs. CCS added expertise across several of its portfolios, bringing on Siena Cicarelli and Ethan Wong to expand its coverage of the security threats posed by climate change, including their intersection with Arctic policy, food security, and the transatlantic relationship. 

Siena joins CCS as a Research Fellow supporting the Nexus²⁵ project, a CCS/Istituto Affari Internazionali (IAI) initiative focused on sustainable multilateralism. She previously covered transatlantic security and international humanitarian policy for the U.S. Department of Defense, Center for American Progress, and Eurasia Group. 

Ethan previously worked on environmental, climate, and international security issues at The Arctic Institute – Center for Circumpolar Security Studies and the NASA Jet Propulsion Laboratory. At CCS, he will support a range of climate security projects as a Research Fellow, such as the Climate Security Fellowship and the Military Responses to Climate Hazards (MiRCH) tracker.
