About Me

I'm a PhD student in the Department of Physics and Astronomy at Stony Brook University. I'm a DOE Computational Science Graduate Fellow, additionally supported by the Institute for Advanced Computational Science.

I've contributed to a number of research projects, from computer science middle school curriculum to gamma-ray pulsars, to explore and expand my research capabilities. I often work at national laboratories, including SLAC National Accelerator Lab, Los Alamos National Lab, and the National Renewable Energy Lab.

I currently work on the AMReX Astro suite of hydrodynamic simulation codes.

I also advocate for kids, and I work to improve students' quality of life. I like to pay attention to effective science outreach, communication, and pedagogy. In my free time, I enjoy music, dance, and games.

Examining Reaction Networks used in Convection Models in Helium Shells of Sub-Chandrasehkar White Dwarfs

This project simulates the explosion of a dense white dwarf star. In the model, a helium layer surrounds the star. Initial ignition of the helium layer can cause the helium, then the star itself, to burn and explode as a type of supernova. Computer simulations of this phenomemon, by necessity, ignore elements or chemical reactions, in order to simplify the problem enough to be tractable. In this work, I explore the sensitivity of the explosion to such modifications by comparing complicated simulations with their simpler counterparts.
