Research and Publications

My research interests are focused on searching for classes of neutrino sources using high energy astrophysical neutrino detectors such as the IceCube Neutrino Observatory (located at the South Pole) and the upcoming Pacific Ocean Neutrino Experiment (P-ONE, proposed for the Cascadia Basin off the coast of Canada). During my PhD I focused on real-time study of astrophysical transients, including compact object mergers, novae, and supernovae/GRBs. The results of many of these searches were published in real-time with low latency via the Astronomer's Telegram or General Coordinates Network (GCN). As a postdoc, I have continued this real-time work, as well as studying extreme blazars as a possible source of high energy astrophysical neutrinos. In addition to my analysis work, as a postdoc I work on characterization of photomultiplier tubes (PMTs) for the Demonstrator phase of the upcoming P-ONE experiment.

The full list of my publications can be found on InspireHEP or ORCID. Below are some of my recent selected publications and conference proceedings.
