Research Interests:
 My research interests have always lain at the boundary between mathematics and
theoretical physics. I have investigated many different topics along these
lines in the last several years, and would like to continue in this vein in the
future.
 I was most recently working on Monte Carlo simulation of elementary-particle
collisions at SSC energies, and also investigating YFS-like exponentiation of
multiple soft-gluon radiation, as well as investigating direct simulation of
events involving production of a Higgs particle, under Dr. Bennie Ward in
the U.T. Knoxville Physics department.
 In former research, at Los Alamos, I investigated the supersymmetric WKB
approximation with Michael Nieto. We attempted to explain why the exact energy
levels appear, as well as what type of potentials may be amenable to this
treatment. We published a paper in Physics Letters B dispelling some
widely-held myths about the SWKB approximation.
 I also worked on cosmic strings, in collaboration with Robert Brown and a group
of students at CWRU. This work grew out of my thesis, in which I found the most
general cosmic string containing two different harmonics and, using numerical
simulations and an approximation method for solving two simultaneous nonlinear
equations, inspected its self-intersectional and fragmentational qualities for
compatibility with cosmic-string galaxy-formation theories. I also found a way
to treat fragmentation analytically, which (among other applications) can serve
as a check on numerical simulations of the process. Continuing to work on this
subject at Los Alamos, we discovered a method of producing the most general
expression (2N+2 parameters) for strings containing any finite number N of
harmonics, based on a rotation-matrix representation of the set of vector
equations involved.
 Other topics I have worked on at various times include supersymmetric analogues
of the Volkov-Taub transformation (which gives an equivalence between a system
of particles interacting with a plane wave and the same system minus the plane
wave) and the associated radiation zeroes, the connections between angular
momentum, turn theory, supersymmetry, and the boson/fermion calculi, a general
classification scheme for modular invariants of conformal field theories, the
question of what supersymmetric coherent plane-wave states might look like,
unitarity bounds on certain radiative-decay amplitudes, the factorization of
certain cross sections involving bremsstrahlung for various-spin particles,
and decomposing certain Feynman integrals into standard easy-to-compute pieces.

Computer experience:
 I have had three years of writing and debugging medium-large FORTRAN programs
while working on the above-mentioned Monte Carlo simulations, as well as
rewriting some sections thereof to be comprehensible to people who were not the
author. I have had experience earlier with Pascal and assembly language in
college, and have also done some debugging of C++ sourcecode. In addition, I
have extensive experience with and knowledge of Unix systems and UseNet News
and have worked with VM/CMS and Mosaic, and have some experience with
explaining the use of Unix systems, editors, and newsreaders to people who were
not particularly familiar with them. I have been assistant sysadmin for a year
or two on the high-energy theory's group of workstations, which includes a Sun
and (currently) two HP workstations (plus several slave terminals & a laser
printer), all running various brands of Unix.
