About

I am a senior at MIT majoring physics and minoring in math. I am interested in high energy astrophysics instrumentation, as well as black holes, gravitational waves, and geometric aspects of general relativity. In my free time, I love lifting, MMA, and DJing :)

Modeling the Performance of the REDSoX/GOSoX Soft X-ray Polarimeters

MIT Kavli Institute for Astrophysics and Space Research
Supervised by Swati Ravi and Herman Marshall
June 2026 – Present

I am developing computational models to predict the performance of the REDSoX and GOSoX soft X-ray polarimeters. My work focuses on modeling the instruments’ energy-dependent response, including zeroth-order effective area and source count rates for REDSoX's target Mrk 421, and calculating the Minimum Detectable Polarization (MDP). I am currently extending the calculations to include multiple target sources for the GOSoX mission, incorporating background models and more complex XSPEC source spectra, and developing an inverse MDP calculator to determine the exposure time required to reach a specified polarization sensitivity.

Formation of Extremal Black Holes in the Einstein–Maxwell Charged Scalar Field System

MIT Department of Mathematics
Supervised by Christoph Kehle
February 2026 – August 2026

I studied the formation of extremal (zero surface temperature) black holes in the spherically symmetric Einstein–Maxwell charged scalar field system. The project aimed to extend recent work on collapse to extremal Reissner–Nordström black holes by removing the coupling constant–mass requirement |eM| ≫ 1 and investigating extremal formation in the case of |eM| ≪ 1.
