Research statement
My PhD thesis is on the detection of low energy (MeV-GeV) neutrinos from Gamma-Ray Burst populations using IceCube.
I am working on using the electromagnetic spectra of Gamma-Ray Bursts to categorize them in order of neutrino production.
For the detection of neutrinos, i am trying to improve the the detection and reconstruction of low energy neutrinos at IceCube. Here I am working on the reconstruction of the direction of a neutrino, using a single string of detectors.

Active projects
Multi-messenger studies of astrophysical sources
Giacomo Bruno, Karlijn Kruiswijk, Jeff Lazar, Jonathan Mauro, Emile Moyaux, Christoph Raab, Leonardo Ricca, Marco Scarnera, Per Arne Sevle Myhr, Gwenhaël Wilberts Dewasseige

This project aims at studying astrophysical phenomena combining different messengers, mainly neutrinos, electromagnetic and gravitational waves.
Neutrino physics and astrophysics
Neutrinos from astrophysical transient sources
Karlijn Kruiswijk, Jeff Lazar, Jonathan Mauro, Emile Moyaux, Christoph Raab, Leonardo Ricca, Marco Scarnera, Per Arne Sevle Myhr, Gwenhaël Wilberts Dewasseige

This project aims at optimising neutrino telescopes, especially the IceCube Neutrino Observatory and KM3NeT, to detect GeV and sub-GeV astrophysical neutrinos. The instruments are then used to search for low-energy neutrinos from transient sources, such as solar flares, compact binary mergers, or gamma-ray bursts.
