Stewart Prager

Stewart Prager was 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.

Researchers poised to deliver key scientific findings in the fast lane

Streaming data, the online process that brings movies, music and videos instantly into homes, is poised to accelerate the worldwide distribution of scientific discoveries in fusion research. Scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) and Oak Ridge National Laboratory (ORNL) have demonstrated the streaming and rapid analysis of findings from a fusion reactor in South Korea to Princeton, New Jersey.

Renowned physicist steps down from Theory Department leadership at PPPL to devote full time to teaching and research

When Amitava Bhattacharjee returned to his academic roots to head the Theory Department at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) in 2012, the department had lacked stable leadership for several years and was nearing a funding crunch. Within a year of Bhattacharjee’s arrival, “the department had a budget crisis that forced us to institute a voluntary separation plan,” he said.
