Dr. Hahm is
a principal research physicist and a distinguished laboratory fellow. He is an elected
fellow of the American Physical Society since 1995. He was the recipient of the Kaul Prize for Excellence in Plasma Physics and Technology Development in 2005. He is the first
author of over 37 papers published in refereed journals. Hahm graduated
with a B.S. in Physics from Seoul National University in Korea (1980).
He then went on to receive an M.A. in Astrophysical Sciences (1982)
and a Ph.D. in Astrophysical Sciences (1984) from Princeton University.
His research interests include the development of reduced nonlinear
kinetic equations in general geometry and applications to gyrokinetic
simulations; the ExB flow shear suppression theory of turbulence in
magnetically confined plasmas; the dynamics of turbulence driven zonal
flows; and momentum transport in tokamaks.
