Amanda M. Johnsen is a Ph.D. student in the Nuclear Engineering Department at UC Berkeley. Her current research interest is in radiochemistry. She has been studying neptunium thermodynamics as part of the Stockpile Radiochemistry group at Lawrence Livermore National Laboratory.

Johnsen grew up in an army family, moving frequently, and her interest in international relations began while her family was living at SHAPE, a NATO base in Belgium, at the end of the Cold War. More recently, her interests are in U.S. national security policy, including nuclear nonproliferation and security.

Before entering UC Berkeley, Johnsen received a B.S. in nuclear engineering from the Massachusetts Institute of Technology. She has interned at Pacific Northwest National Laboratory on a nuclear fuel development project and at Bettis Atomic Power Laboratory, a research lab that designs nuclear reactors for the U.S. Navy.
