About me

Hello! I am postdoctoral scholar at the Center for Astrophysics and Space Sciences at UCSD where I study the properties of germanium detectors in order to predict how the detectors aboard the Compton Spectrometer and Imager (COSI) will be affected by collisions with high-energy protons in orbit. My astronomy research focuses on accreting objects, including low-mass X-ray binaries, supergiant X-ray binaries, and ultra-luminous X-ray sources. I am particularly interested in the varied and extreme phenomena that arise due to accretion onto neutron stars, such as X-ray pulsations and thermonuclear bursts.

Community organizing and service

I feel compelled to build communities based in care and compassion. Below are a few of the ways I've done that at Caltech.

Socialists of Caltech

As a founding member and previous co-chair of the Socialists of Caltech, I have worked with other students to help make our communities better places to live for working people. I have run regular reading groups, designed lessons for outreach to local schools, and helped to write and pass legislation which will protect local renters.

CaltechY RISE tutoring

As a CaltechY RISE tutor, I taught local high school students math and physics for several years. I have a deep love for teaching, and I strive to provide a welcoming environment in which students can build their confidence and their understanding at the same time.

Caltech for Black Lives

I cofounded and served as a co-chair of Caltech for Black Lives. We worked closely with the Black Scientists and Engineers of Caltech (BSEC) to make Caltech a safer and more welcoming place for those belonging to minoritized groups.
