John A Krommes
Prof. Krommes is a Principal Research Physicist at the Plasma Physics Laboratory, a Lecturer With the Rank of Professor in the Dept. of Astrophysics (Plasma Physics Program), and an Associated Faculty Member of Princeton's Program in Applied and Computational Mathematics. He received his BS degree (summa cum laude) in 1971 from the Pennsylvania State University, where he majored in Engineering Science. In 1975 he received the PhD degree from Princeton University's Dept. of Astrophysics, presenting under the supervision of Carl Oberman a dissertation entitled ``On Renormalized Kinetic Theories of Anomalous Transport due to Hydrodynamic Fluctuations in Strongly Magnetized Plasma.'' He then enjoyed a two-year post-doctoral appointment under the supervision of Marshall Rosenbluth at the Institute for Advanced Study, where among other things he worked on the theory of trapped-ion modes and the unification of various theories of plasma turbulence.
Prof. Krommes returned to PPPL in 1977, where he has remained ever since except for two extended research leaves at the Institute for Theoretical Physics in Santa Barbara. He teaches a second-year graduate course on kinetic theory and irreversible processes, as well as an advanced course on plasma and fluid turbulence. His research interests have included the theory of transport in stochastic magnetic fields; statistical theories of turbulence; nonlinear gyrokinetics; rigorous bounds on turbulent transport; zonal flow generation; systematic bifurcation theory for the onset of turbulence; and intermittency, including blob formation. A side interest is Literate Computer Programming; he is the author of the widely used FWEB suite of preprocessors. Two review articles summarize much of his research: (i) "Fundamental statistical theories of plasma turbulence in magnetic fields," Phys. Reports 360, 1-351 (2002); (ii) "Nonequilibrium gyrokinetic fluctuation theory and sampling noise in gyrokinetic particle-in-cell simulations," Phys. Plasmas 14, 090501 (2007).
Prof. Krommes is the recipient of several awards. He is a Fellow of the American Physical Society. In 2002 he was named a Distinguished Research Fellow at the Plasma Physics Laboratory. He received the Graduate Mentoring Award from Princeton University in 2005.
