  • About

I’m a third-year DPhil student at the University of Oxford, working in the ATLAS Exotics Group under the supervision of James Frost and Todd Huffman. My research focuses on searches for dark-Higgs production in the hh->4b+MET channel, where I’m responsible for the statistical interpretation. This involves implementing a profile-likelihood fit to extract the behaviour of nuisance parameters and the key signal normalisation factor—ultimately quantifying the presence, or absence, of a dark-Higgs signal given the observed data. Alongside this, I’m working on calibrating the GN2 flavour-tagging algorithm, a transformer-based graph neural network designed to enhance jet flavour identification across the ATLAS experiment.

Beyond ATLAS, I’m exploring the potential of a future circular hadron-hadron collider to study Higgs self-interactions, particularly through triple-Higgs production. The aim is to constrain the trilinear and quartic Higgs self-couplings, which are crucial for understanding electroweak symmetry breaking and the Higgs potential.
