Paolo Desiati is a research professor at the Wisconsin IceCube Particle Astrophysics Center (WIPAC), a center at the University of Wisconsin-Madison. His research focuses on cosmic ray physics through his work with the IceCube Neutrino Observatory, the High Altitude Water Cherenkov (HAWC) Observatory, and the Southern Wide-field Gamma-ray Observatory (SWGO), performing experimental analyses and simulation studies of cosmic rays. He collaborates with various teams to create multi-experiment combined analyses, aiming to provide comprehensive insights into the complexities of cosmic rays. Additionally, Paolo conducts numerical calculations of particle trajectories using computational astrophysical magnetic field models to develop theoretical frameworks for testing against observational data.

• March 2025: Research Paper - The anisotropy analysis results obtained by the cosmic-ray teams at UW-Madison, Mercer University, and Loyola University Chicago using 12 years of IceCube data (collected from May 2011 to May 2023) was published on The Astrophysical Journal.
• March 2025: Research Paper - The paper on Chaotic Behavior of Trapped Cosmic Rays, based on the research performed in collaboration with colleague Dr. Vanessa López Barquero, was accepted for publication on The Astrophysical Journal (see the paper on the arXiv).
• October 2024: Conference - Organizer of the SuGAR 2024 Symposium, Searching for the sources of galactic cosmic rays, hosted at WIPAC. The symposium aims to investigate the long-standing mystery surrounding the origin of cosmic rays within our galaxy. This event will bring together renowned experts to discuss both experimental and theoretical aspects of cosmic ray physics, with a particular emphasis on galactic sources. Despite ongoing research, the question of where cosmic rays originate within the Milky Way remains unanswered. The symposium will host a number of invited speakers who are experts in various aspects of galactic multi-messenger astrophysics. Furthermore, two dedicated discussion panels will provide opportunities for open discussion. One panel will delve into the current status and challenges of multi-messenger observations and theoretical modeling. The other will address the future of observations and instrumentation required to make a breakthrough in our understanding of the galactic origin of cosmic rays.
• May 2023: Conference - WIPAC and Loyola University - Chicago organized the sixth edition of the Cosmic Ray Anisotropy Workshop (CRA 2023). The Workshop will bring together scientists from around the world to discuss the origin, composition, propagation, and modulation of cosmic rays, focusing on the anisotropy on small and large scales and the effects of interstellar and heliospheric processes on the signal observed at the Earth.
