Biography

I am a postdoctoral researcher at Nikhef (the Dutch National Institute for Subatomic Physics) in Amsterdam, where I am a member of the theory group. My research focus is particle physics phenomenology, which is the interface between theory and experiment. The goal of this field is to interpret the vast amount of data produced by particle colliders, such as the Large Hadron Collider (LHC) at CERN, in order to test the Standard Model of particle physics and search for signs of new fundamental laws of nature.

I am an active member of two international theory collaborations. SMEFiT develops precision analyses based on Effective Field Theory (EFT), a systematic framework to parametrise possible new physics beyond the Standard Model and confront it with current and future collider measurements. PBSP extends this program by incorporating a detailed treatment of the internal structure of the proton, encoded in Parton Distribution Functions (PDFs), which is a major source of uncertainty in high-energy collider physics.

I am also a member of the FASER experiment at CERN, which studies some of the most elusive particles produced at the LHC: neutrinos. We aim both to better understand this mysterious sector of the Standard Model and to search for possible new physics beyond it.

In parallel, I investigate how modern machine-learning techniques, such as unbinned analyses based on neural simulation-based inference, can improve the extraction of physical information from collider data.

I completed my PhD at the University of Cambridge, in the Department of Applied Mathematics and Theoretical Physics where I worked with Prof. Maria Ubiali. I began my academic training in France at Lycée Saint-Louis and Ecole polytechnique.
