• Fundamental-interaction physics at the LHC (ATLAS) – Higgs-boson studies, with a focus on associated production with top quarks (tt̄H) and multiboson channels. Precision measurements of the top-quark cross-section and of rare processes. Development of jet-reconstruction algorithms, especially for boosted topologies or when muons appear in the hadronic decay chain.

• Quantum technologies and quantum computing – Member of the Project Management Board of QUART&T (Quantum Architectures for Theory & Technology): development of superconducting-qubit demonstrators with all-to-all connectivity and qudits based on Josephson junctions in resonant cavities; applications to HEP tools (QUnfold, quantum annealing for spectrum unfolding).

• Data-analysis methods & ML – Application of advanced Kalman filters, machine-learning techniques and optimisation on HPC resources (CINECA) for the High-Luminosity LHC and for emerging quantum sensors.

• Searches for new physics (BSM) – heavy neutrinos & exotic signatures – Coordination of ATLAS analyses devoted to type-I/III heavy neutrinos and vector-like leptons; study of multilepton signatures and seesaw scenarios.

• Applied physics to hadron-therapy and space-radiation protection (FOOT experiment) – Measurement of fragmentation cross-sections of light nuclei (C, O, He) to reduce dose uncertainties in proton-/carbon-therapy and in long-duration space missions; implementation of a Combinatorial Kalman Filter for track reconstruction, data acquisition and analysis.
