My principal area of research is theoretical plasma physics,
and
recently my
investigations have
centered on nonneutral plasmas (pure electron plasmas, pure
ion plasmas, positron plasmas, etc.).
These systems provide simple,
theoretically tractable models for many of the phenomena associated with
neutral plasmas, and also exhibit unique (and fascinating!) behavior in their
own right.
For example, there is international interest in the low-temperature
behavior of these systems, in which liquid and even crystal states are
predicted to occur.
My studies of this interest
ing many-body system employ
techniques which are drawn from a range of disciplines including plasma
physics, statistical mechanics, nonlinear dynamics, computer simulation, and
quantum mechanics.
