My research has broadly focused on three main topics: Type Ia Supernovae, Irradiated Brown Dwarfs, and Stellar Contamination, elaborated more below. Click on the images to learn more about each topic!
The Stellar Treasure Trove: Going through all archival HST observations of transiting exoplanets, re-reducing the data with updated methods, gaining more information about the Out-of-Transit stellar spectra and characterizing the intrinsic stellar variability — a previously ignored phenomenon.
Understanding Stellar Variability enables more precise Exoplanet Characterization
As studies of exoplanets becomes more advanced, the signals we are analyzing have gotten incredibly small. So small that they near or at the same magnitude as signals from the host star. Thus, it is imperative that we develop a framework for disentangling the signals between host star and exoplanet.
PhD Thesis Title— Illuminating Brown Dwarfs: Exploring the Impact of Irradiation in Ultracool Atmospheres Through Phase-Resolved Spectroscopy
Atmospheric Characterization of Irradiated Brown Dwarfs helps us understand all atmospheres
For my PhD thesis, I studied the atmospheres of brown dwarfs in ultra-short period white dwarf-brown dwarf binaries. These highly irradiated ultracool atmospheres enable us to test the presence of predicted condensate cloud formation, study day-night heat redistribution in unprecedented detail, and build an observational link between field brown dwarf and hot Jupiter studies.

Constraining the Single Degenerate Scenario: Connecting Early Light Curve Clues with H/He Upper Limits from Nebular Spectra.
For the first part of graduate school, I studied the chemical makeup of Type Ia Supernovae explosions. These supernovae are very important to Astronomy, since they can tell us how fast the Universe is expanding, yet we still don’t know what causes the carbon-oxygen white dwarf to explode or even how the explosion happens. My research focused on connecting observational clues in the first hours after explosion and after ~200 days.
