Research

My research connects the phenomenology of the top quark and dark sectors with the scientific software that makes those analyses reproducible. I aim to pair each project with an open, reproducible computational tool.

Dark Matter with top quarks

Production of top quarks in association with dark matter in simplified models: the 2HDM+a model, a principal LHC dark matter benchmark, and top-philic dark matter scenarios in which the dark sector couples to the top quark. This work builds on the t-channel dark matter models whitepaper (EPJC 85, 975, 2025); the associated pipeline in Python and Julia (MadGraph/MadDM, FeynRules) is in development.

Spin correlations at lepton colliders

Spin-correlation observables in top quark production as precision probes of top quark interactions and physics beyond the Standard Model, relevant to the physics programs of future lepton colliders such as the FCC-ee top-threshold run, the ILC, and CLIC.

Hidden particles at SHiP

Feebly interacting and long-lived particles, heavy neutral leptons and dark sector states, at the SHiP (Search for Hidden Particles) experiment. This continues the physics of previous results, such as Probing the type-I seesaw mechanism with displaced vertices at the LHC (EPJC 75, 470, 2015). An early Julia toolkit for fixed-target hadron production and backgrounds, FixedTargetBackgrounds.jl, is in development.

Precision Higgs analysis

A numerical Higgs sector analysis implemented in Fortran, developed as both a physics study and an open-source, tested software tool.
