I am a second year Ph.D. student studying Computational Science and Engineering at Georgia Institute of Technology.
My primary research is on the modeling of gas liquid interfaces under high amplitude accelerations, but I also make regular
contributions to MFC, an exascale ready multiphase flow code that scales to 10's of thousands of GPUs. When I'm not busy with school
or research I enjoy spending time outdoors camping, hiking, and climbing or indoors playing board games and enjoying a craft beer.
Some of my Work
Vorticy Shedding of a Shock Inpinged Droplet
Atomization of a 3D water droplet in air impinged by a Mach 1.46
shockwave. A 2000 x 1000 x 1000 cartesian grid is used to discretize the computationl
domain. The flow was simulated for 200k time-steps with snapshots saved every 1k
time-steps. The simulation required four hours of wall time using 960 GPUs on OLCF
Summit. The video shows the development of the isosurface at which the vorticity is
Breakup of a Vibrated Air-Air Interface
Breakup of an air-air interface subjected to an oscillatory accelerating of 30g at 150 Hz in
the vertical directions. A 500 x 500 x 5000 catesian grid is used to discretized the Computational
domain. The flow was simulated for 250k time-steps with snapshots saved ever 1k time-steps. The
simulation required six hours of wall time using 1320 GPUs on OLCF Summit. The image shows snapshots
of the interface breakup at 0.25s intervals.

Relevant Work Experience
Defence Science and Technology Intern - Lawrence Livermore National Lab
June 2022 - August 2022
In this position I taught myself how to use ALE3D for the purposes of modeling a high explosive point to line generator
with the purpose of accelerating flyer plates for the measurement of dynamic material properties.
Summer Intern - Lawrence Livermore National Lab
June 2021 - August 2021
In this position I performed all-atom and coarse-grain molecular dynamics calculations using LAMMPS to model polymerization
for volumetric additive manufacturing.
