A Catalog of M & M Eclipsing Binaries with TESS
Identified ~1,300 M-dwarf eclipsing binaries across the sky, characterizing their orbital periods, eclipse times, radii, masses, temperatures, and population-level eccentricity distributions.

About
From Cleveland to the cosmos
I grew up near Cleveland, Ohio, where a childhood passion for Science Olympiad grew into a lifelong love of science. I'm fascinated by the opportunity to study what else is beyond our own Solar System, which can help us understand our own context by comparison.
I completed my B.S. at Case Western Reserve University in 2020 and have recently defended my PhD at the University of New Mexico, studying transiting exoplanets with a focus on circumbinary planets. Outside the office I'm a cat dad to Chini, an avid runner and hiker, a baker, and a proud jazz and D&D nerd.

Current focus
- Developing a circumbinary planet detection pipeline for TESS to measure the first occurrence rate from that mission.
- Published a catalog of ~1,300 M-dwarf eclipsing binaries with orbital & physical properties.
Coming soon!
- The occurrence of M & M CBPs with TESS — paper based on my dissertation chapter in the works!
Research
Selected work
Photometric comparisons, M-dwarf binaries, and circumbinary planets through the lens of TESS.
M & M CBP occurrence rate
For the first time, calculated CBP occurrence rates using TESS data. This has implications for the robustness of planet formation in the low-mass, tight binary context.
Comparing TESS and CHEOPS Photometric Precision
Analyzed 10 planets observed by both TESS and ESA's CHEOPS mission as a comparison of the relative photometric performance of the two space missions.
Community
Inside and outside the workplace
Science and society don't exist separately from one another. Here's where I show up outside research.
UNM Graduate Workers Union
Graduate workers have been overworked and undervalued for too long. For nearly my entire graduate career, I was involved with UNM Graduate Workers in several capacities, including as a co-lead negotiator for the Spring 2024 raise and as Director of Organizing in the 2024-2025 AY.
UNM PUMP
The Peer Undergraduate Mentorship Program in UNM Physics & Astronomy pairs grad students with undergrads navigating the same journey we were on just a few years ago. It sharpens mentorship skills on both sides and strengthens the department as a whole.
ABQ Community Commons
I've been honing my skills as a web developer to create an alternative to social media. Data-hungry corporations use our attention for profit, so many folks (myself included) want to get off social media, but there's real benefit to being connected and knowing what's happening. Check out the site (and please post!)
