High-energy astrophysicist searching for astrophysical sources emitting high-energy neutrinos, gravitational waves, and electromagnetic signals. Teaching the Frontiers of Science course integrating modern science in the Columbia core curriculum.
My research interests lie in high-energy astrophysics, multi-messenger astronomy, and particle astrophysics. I search for astrophysical sources that emit multiple types of signals including neutrinos and gravitational waves. My colleagues and I perform rapid electromagnetic follow-up of neutrino and gravitational wave alerts to study their multi-messenger sources.
