I was personally involved in or led a few:

  • Cosmic Neutrino Probes of Fundamental Physics [pdf]
  • Neutrino cross-sections and interaction physics [pdf] (with Amy Connolly & Spencer Klein)
  • New physics with astrophysical neutrino flavor [pdf] (with Carlos Argüelles, Teppei Katori, Ali Kheirandish, Sergio Palomares-Ruiz, Jordi Salvadó, Aaron Vincent)
  • Ultra-High-Energy Neutrinos [pdf] (with Peter Denton & Stephanie Wissel)
  • Target of Opportunity Observations with Next-Generation High-energy Neutrino Observatories [pdf] (with Claire Guépin & Tonia Venters)
  • An Andean Deep-Valley Detector for High-Energy Tau Neutrinos [pdf] (with Carlos Argüelles & Andrés Romero-Wolf)
  • GRAND: Giant Radio Array for Neutrino Detection [pdf]
