Cornell University
Primary responsibility for externally sponsored research programs at all
stages, including writing proposals, conducting research, reporting results.
Have been awarded funding and equipment for computer simulation and data
analysis projects ranging from elementary-particle tracking at the LHC (NSF)
to turbulent combustion (DoD, NASA), as well as diffraction-limited optical
imaging through fused silica glass (Corning Inc.) and the convection dynamics
of ionization zones in the solar interior (NSF). Duties extend to training
users of high-performance computing (HPC) resources at TACC (NSF's Frontera,
Stampede2, Stampede, Ranger) and Cornell (Red Cloud, clusters); consulting
for Cornell faculty and staff on computational matters; and advising student
researchers. Example: produced the first-ever set of benchmarks of parallel
Fluent on large, commodity-based clusters of Windows servers demonstrating
good scalability.

[1991-93] NSF Postdoctoral Research Associate, Cornell Theory Center/Center for
Radiophysics and Space Research (jointly), Cornell University. Was awarded a
grant from the National Science Foundation in a national competition.

Contributed to work in progress on MHD turbulence theory and assisted in
applying results to an analysis of plasma data from the Voyager 1 and 2
satellites. Some results of the project were published (see below).
))) Ph.D. Thesis Research:
Study of magnetic field dynamics in the solar convection zone by explicit
numerical solution of the magnetohydrodynamic (MHD) model equations in two
dimensions. The "anelastic" approximation was utilized, which builds a
density and temperature stratification into the model but filters out sound
waves. Approximate solutions to these partial differential equations were
found by a combination of finite-difference and spectral methods. Simulations
of the evolution of flow fields and large-scale magnetic structures were
computed and compared to predictions from a low-order (Lorenz-type) model of
chaotic convection, as well as to solar observations. Because video
visualization was an important part of this work, a 20-minute videotape (at
that time, a technological feat) was submitted as an accompaniment to the
written document.
