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.
