Probing the extreme edges of the Universe.
I use space- and Earth-based telescopes to study black holes and exploding stars. My research has contributed to the first images of black hole shadows and uncovered new clues to how massive stars die.

The first images of a black hole
As a collaborator on the Event Horizon Telescope project, I helped take the first image of a black hole. I work primarily on imaging (turning the data we collect from observations into images), modeling (making assumptions about the form of the data and finding models that best fit it), and theory (developing the physics behind our understanding of the shadow of a black hole).
I was a key contributor to the second image of a black hole--the first image of the supermassive black hole in the center of the Milky Way. I led one of the 10 papers published as part of the results package on May 12, 2022, establishing a new method for obtaining high-frame-rate movies of Sgr A*.

The deaths of massive stars
Type IIb supernovae are the result of a core-collapse explosion of a massive star that has shed almost all of its hydrogen envelope. The mechanism by which the hydrogen envelope is shed is not well-understood and could be explained by several different channels (e.g., stellar wind, binary stripping, precursor eruption], etc.) which are challenging to constrain observationally. Understanding this mass-loss mechanism is a crucial topic of interest. By combining early-time observations with shock cooling models and optical follow-up from global telescope networks, I’ve helped constrain the mass loss mechanisms and ejecta properties of these transitional core-collapse events.

The Black Hole Explorer
The Black Hole Explorer (BHEX) is a next-generation space VLBI mission designed to image black holes with unprecedented resolution by extending the Event Horizon Telescope into orbit. I contribute to the development of BHEX by designing analytic and deep learning techniques to extract physical parameters from photon ring structure in the visibility domain. My work focuses on leveraging the n=1 photon subring, a subtle yet powerful signature in interferometric data, to enable precision tests of strong gravity. I have led efforts to simulate BHEX observations, develop parameter inference pipelines, and produce some of the first machine learning–driven measurements of black hole spin from synthetic BHEX datasets.

My ultimate goal is to characterize the strangest objects in the Universe, from supernovae to black holes. As a member of the Global Supernova Project, I will apply the methods we've developed for Type IIb supernovae to data from the upcoming Rubin observatory. As a member of BHEX, I will continue developing the science case for the spacecraft and refine methods to convert observations into detections and measurements of the elusive photon ring.
