Before moving into data science, I studied complex astrophysical systems through numerical simulation—from instabilities in relativistic plasmas to cosmic-ray feedback in galaxies.
Published · 2026Featured publication
Our particle-in-cell simulations isolate the interaction between Kelvin–Helmholtz and drift–kink instabilities. Together, they enhance dissipation and produce a new, efficient path for accelerating particles.

Selected projects
Magnetohydrodynamics · Disk physics
Investigating whether magnetic fields generated by the magnetorotational instability can promote gravitational collapse in rotating disks—and how that effect competes with magnetic elevation.
