Stewart Prager

Stewart Prager is the sixth director of PPPL. He joined the Laboratory in 2009 after a long career at the University of Wisconsin in Madison. At Wisconsin, he led research on the “Madison Symmetric Torus” (MST) experiment and headed a center that studied plasmas in both the laboratory and the cosmos. He also co-discovered the “bootstrap current” there—a key finding that has influenced the design of today’s tokamaks. He earned his PhD in plasma physics from Columbia University.
