Gregory W. Hammett

Gregory W. Hammett is a Principal Research Physicist at the Princeton Plasma Physics Laboratory (PPPL) and a Lecturer With Rank of Professor in Princeton University's Graduate Program in Plasma Physics. He is also an Associated Faculty member of the Program in Applied and Computational Mathematics. His research focuses on computational and theoretical studies of plasma turbulence in fusion and astrophysical contexts, emphasizing gyrokinetic simulations and advanced numerical algorithms. He holds a B.A. in Physics from Harvard University (1980) and a Ph.D. in Astrophysical Sciences from Princeton (1986).

Hammett leads the Gkeyll team developing a discontinuous Galerkin-based gyrokinetic code for edge plasma simulations. He has been a Fellow of the American Physical Society since 1997 and received the Maxwell Prize in 2024. His teaching includes courses on plasma physics, turbulence, and numerical methods. Notable collaborations include work with the Max-Planck/Princeton Center for Plasma Physics and involvement in projects like the GENE and GS2 gyrokinetic codes.

His advisory work includes mentoring over 15 graduate students, with contributions to fusion energy research through studies of plasma confinement, scrape-off layer turbulence, and magnetic mirror systems. He has authored/co-authored over 150 publications, with recent focus on electromagnetic edge turbulence models and full-f gyrokinetic simulations.
