(September 2021 - Present) Ph.D. Student at Princeton Program in Plasma Physics. First-year project.
Optimizations for gyrokinetic modeling for high-field magnetic mirror experiments using Gkeyll.
- Currently thinking about non-uniform grid discontinuous Galerkin schemes
- Developed a unit test for the C-level Gkeyll implementation to facilitate the GPU implementation.
- Implemented a penalization term to turn off the high forces imposed in inaccessible regions of phase space. This resulted in a speed-up of 20X

Studying the E&B model presented in Chen (2020) "A gyrokinetic simulation model for low-frequency electromagnetic fluctuations in magnetized plasmas"
- Recreating the results from this paper.
- Extending the model to tokamak geometry.

Solving Poisson’s equation on GPU for application to particle-in-cell codes.
- Utilized the linear algebra package Hypre on Princeton’s supercomputer Traverse to investigate the performance of solving Poisson’s equation on GPUs.
(Summer 2020) Summer Undergraduate Laboratory Internship at Princeton Plasma Physics Laboratory
Fast ion modeling using a 2D Chebyshev approximation for the magnetic potential.
- Created a partially kinetic simulation for fast ions on GPU to simulate particle loss from neutral beam injection on the Lithium Tokamak Experiment.
(September 2019 - June 2020) Staff Associate at Columbia Plasma Physics Laboratory at Columbia University
A multi-staged biorthogonal decomposition for finding disruption-causing modes on HBT-EP.
- Through exploratory efforts, invented an algorithm to find disruption-causing modes across many shots. It is finding the biorthogonal decomposition of the mirnov coil sinals on many different shots, then computing the biorthogonal decomposition of those modes to find the best representation of the dominant biorthogonal decomposition modes.
- Wrote a random forest algorithm to predict disruptions.
- Defined a 2D Lomb-Scargle periodogram for unraveling the structure of magnetic diagnostic data.
