Nuclear science and engineering graduate students Leslie Dewan and Mark Massie and recent alum Robert Petroski PhD ’11 have been named to the Forbes "30 Under 30" list in the energy sector for 2013.

Dewan and Massie were cited for their work on a new kind of molten salt reactor optimized to run on spent fuel discharged from conventional light water power reactors. Petroski was cited for his design work on the traveling wave reactor, a new kind of reactor under development by the start-up TerraPower.

Dewan’s doctoral research, with advisor Professor Linn Hobbs, is focused on computational modeling of nuclear materials. She obtained SB degrees in nuclear engineering and mechanical engineering from MIT in 2007, and currently holds a DOE Computational Science Graduate Fellowship.

Massie’s PhD research, with NSE Assistant Professor Benoit Forget, specializes in nuclear reactor core design. He has an SM in nuclear science and engineering from MIT, and a B.S. in nuclear engineering from the University of Tennessee. Massie holds a DOE Graduate Fellowship awarded through the Nuclear Engineering University Program.

Petroski received his PhD in nuclear science and engineering in 2011. His dissertation research, with NSE Assistant Professor Benoit Forget, focused on breed-and-burn reactors and limited-separation fuel cycles. He is currently an engineer at TerraPower.
