COSI is an upcoming gamma-ray telescope scheduled to launch in summer 2027. It will detect gamma-ray bursts, determine their locations, and measure their energy spectra and polarization. I serve as the Early Career Co-Lead for the COSI Gamma-Ray Burst Science Team, predict the rate of gamma-ray bursts COSI is expected to detect, develop the spectral and polarization analysis software, and have created tools to simulate population-level COSI transient observations.
In 2025, the Fermi Gamma-ray Burst Monitor detected GRB 250702B, the longest-duration gamma-ray burst ever observed. Its extreme duration and gamma-ray properties cannot be explained by any known origin of gamma-ray bursts. One possible explanation is a stellar-mass black hole merging with a star, consuming it from within, and ultimately destroying the star in an explosion. This work was featured in media outlets including a NASA press release, BBC Sky at Night, National Geographic, and Sky and Telescope.
