Research statement
I am an astroparticle physicist, member of the IceCube and the KM3NeT collaborations. I have mainly focused so far on low-energy (MeV-GeV) neutrinos coming from transient events, such as solar flares, core-collapse supernovae, and compact binary mergers.
My work has three different directions:
- I push the detection limits of each instrument, lowering down the threshold to sub-GeV energies;
- I carry out searches for these low-energy neutrinos, developing new strategies to cope with a significant atmospheric and environmental background inherent to this energy range;
- I convert the obtained limits into constraints on physical parameters of the studied transient sources.
I strongly believe the combination of different messengers, as neutrinos, electromagnetic and gravitational waves, as well as the use of advanced data science tools in joint analyses are the key to unravel the mysteries of our Universe and the high-energy phenomena it contains. This is hence the main direction of my Astroparticle group at CP3.

(member since March 2022)
During my PhD, I have been working on the T2K neutrino experiment, mostly looking for hypothetical heavy neutrinos using T2K near detector, but also participating to the upgrade of T2K near detector. Then, I obtained a 3-year post-doctoral fellowship in INFN Padova (Italy), where I have been focusing on multi-messenger neutrino astronomy, especially the search for neutrinos in time and spatial coincidence with gravitational waves detected by LIGO/Virgo, using the Super-Kamiokande detector. I spend 10 months as secondment in APC Paris (France) to extend this work to ANTARES telescope. Since I am in Louvain, I am mostly focusing on topics related to multi-messenger astronomy in KM3NeT (GW follow-up, real-time astronomy) and in IceCube (low-energy neutrino selection, service tasks related to supernova monitoring and detection).

I am a PhD student in astrophysics, and a member in the IceCube collaboration. My PhD thesis is on on low energy (MeV-GeV) neutrinos from Gamma-Ray Burst populations. For this I work on improving the detection and reconstruction of low energy neutrinos, and look at properties of the electromagnetic spectra of Gamma-Ray Bursts to categorize them.

Building theoretical neutrino energy distributions (NEDs) over a wide energy range for various astrophysical transient events. The final goal of my thesis is to build mock NEDs from these theoretical distributions, which will help us identifying astrophysical sources in both archival and future data.

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.

Outreach and Education
I am passionate about science communication. I am especially interested in developing large-scale outreach programs that can reach a broad audience and trigger science discussion within families and friends. I have for example designed a experiment contest that was asking the participants to develop an experiment that would have a different result in Belgium and at the South Pole. This effort was awarded the annual prize for science communication by the Belgian Academy for Science and Arts in 2017. More recently, I designed and organised on behalf of the KM3NeT Collaboration a drawing contest. The participants had to draw a neutrino. More than 500 drawings from 16 different countries.
I am also interested in science and art projects. I collaborate with Donald Fortescue, PhD in Art and professor at the Californian College of the Arts in San Francisco. Together we are searching for more inclusive ways to present scientific data that can optimize the scientific output and reach a larger fraction of the population. A concrete example of our collaboration can be seen online (http://www.donaldfortescue.com/video#/axis-mundi/).
I also engage in citizen science. I designed, within the EU REINFORCE Consortium an activity on the Zooniverse platform that proposes to participants to classify bioluminescence signatures recorded with KM3NeT.
