Chase Thalheimer is an assistant director at the Atlantic Council Global Energy Center, where he focuses on clean energy transitions in developing countries and US partnerships in emerging clean technology markets. He is also interested in the relationship between energy and security, pertaining to preventing the exploitation of dual-use nuclear technology, materials, and expertise.

Prior to joining the Council, Thalheimer worked at Coalescion, a Virginia-based nonprofit organization, initially as a member of the inaugural Emerging Practitioners in International Security Program and eventually becoming a project lead. In this role, he managed and supported projects on US government-funded counterproliferation and export control-focused capacity building programs and engagements in the Middle East and Southeast Asia.

Thalheimer earned a bachelor’s degree in international relations from Tufts University. His capstone project analyzed the likelihood of proliferation of nuclear/radiological weapons and devices by state and non-state actors associated with the deployment of small modular reactors intended for peaceful use, such as civilian energy generation.
