Research interests
Studying the most basic constituents of matter, and how they interact with each other, is the primary challenge of particle physics.
My research primarily involves the study of rare processes, such as rare decays of B-hadrons (bound state of quarks including a bottom quark) with the LHCb experiment at CERN's Large Hadron Collider.
Over the past decade, our measurements have revealed significant tensions with SM predictions, pointing to the potential existence of a new fundamental force of nature. My current efforts focus on understanding the exact cause of these tensions, be they due to new physics, unaccounted hadronic effects in theory predictions, or experimental artefacts.
In terms of detector development, I investigate the use of novel computing architectures in particle physics workflows to cope with the vast amount of data in next-generation experiments. For instance, Graphcore’s Intelligence Processing Units have proven to be a promising avenue that can resolve many of the limitations of existing computing architectures.
