Research interests
I am a member of the CMS and DUNE collaborations. My instrumental work is to develop fast online data processing systems, that are required to handle the vast amounts of data produced by both experiments. I use programmable logic devices (FPGAs) to implement algorithms which can identify signatures of interesting physics in the data, and select them for further offline analysis.
At CMS, I have performed searches for dark matter production via decays of the Higgs boson, as well as searches for exotic long-lived particles predicted by extensions to the Standard Model.
On DUNE, I am interested in detecting neutrinos from supernovae, which present a major challenge for the data processing system. I am also exploring possible measurements of neutrinos from other astrophysical sources.

Teaching
My teaching actitivies for AY23/24 include Probability and Statistics (Yr 1), Physics Laboratory (Yr 2), Computational Physics (Yr 3), Cloud Technology (Yr 4 Physics/Chemistry with Computational Science). I also offer final year projects in particle physics data analysis and ML methods for real-time processing. In my role as School of Physics Academic Integrity Officer I also provide training and support in academic integrity.
