My research in the Winslow group is on using KamLAND as a neutrino telescope for multi-messenger astrophysics. Neutrinos from astrophysical sources can be used to study extreme environments that are unattainable in labs. I simulate core-collapse supernovae neutrino signals in KamLAND. These neutrinos are probes of the stellar interior during collapse and carry information about the properties of neutrinos.Additionally, these neutrinos can serve as harbinger’s of supernovae optical signals. I also use KamLAND’s data to search for neutrino signals from other astrophysical sources like gamma-ray bursts and X-ray binaries.
