PhD Candidate, NC State University · Computational Astrophysics
I'm a PhD candidate in computational astrophysics at NC State University, working with Dr. Carla Fröhlich. I study the deaths of massive stars through large-scale numerical simulations.
Research
Gravitational waves from core-collapse supernovae. I simulate core-collapse supernovae and study the gravitational-wave signals they produce, and what those signals could tell us about the physics of the source.
r-process nucleosynthesis in collapsars. I model the accretion disks that form when a rapidly rotating massive star collapses to a black hole, and study how these disks could produce heavy elements through the rapid neutron-capture (r-) process.
Methods
- ELEPHANT: 3D magnetohydrodynamics supernova code on a fixed Cartesian grid, used for my core-collapse supernova simulations.
- νbhlight (nubhlight): 3D general-relativistic radiation hydrodynamics with Monte Carlo neutrino transport, used for my collapsar disk simulations.

The notes here go back to my undergraduate years at St. Xavier's College in Kathmandu, and cover physics, mathematics and programming I found interesting.
