Mini-biography

After defending my PhD thesis on Hadron Collider Tests of Neutrino Mass-Generating Mechanisms in 2015, I joined Durham University's Institute for Particle Physics Phenomenology (IPPP) in the UK as a Research Associate / postdoctoral scholar. In 2018, I moved to the Center for Cosmology, Particle Physics, and Phenomenology (CP3) at the Universite Catholique de Louvain in Belgium as a University Research Fellow. I started at IFJ in 2021 and was awarded my habilitation for "theoretical investigations into vector boson scattering" in 2024.

Research

By training, I am a collider theorist. I like neutrinos, lepton number violation, QCD, helicity polarization, and gauge theories in soft/collinear limits. Sometimes I write open-sourced simulation software. Sometimes I work with ATLAS and CMS. Sometimes I do nuclear physics (or particle physics at the boundary with nuclear physics.) I am particularly interested in collider signatures involving initial-state vector bosons (vector boson fusion/scattering).

Some software can be found here (GitLab) and here (FeynRules).
