I study the most powerful explosions in the universe, known as gamma-ray bursts. They are brief flashes of gamma-rays known to occur as the result of the collapse of rapidly-rotating massive stars or neutron star mergers. I make predictions for the gamma-ray burst observations that will be made by COSI, an upcoming gamma-ray space telescope and am the technical lead for the COSI gamma-ray burst science group. I also analyze gamma-ray bursts detected by the Fermi Gamma-ray Burst Monitor.
