My research is primarily focused on investigating the complex structure and consequences of interactions in particle physics. This requires a detailed understanding of the structure of unphysical divergences in perturbative Quantum Field Theory, and their connection to the factorization of long- and short-distance physics. Precision calculations of Quantum Chromodynamics (QCD), encoded into of Event Generator software, are an ideal tool to address these questions. At the same time, precision Event Generators provide crucial background assessment tools to the collider physics community. More concretely, I work on high-precision fixed-order calculations, their matching to parton showers, and on understanding the infrared structure of QCD through developing next-to-leading order parton showers. This has recently also led to a new perspective on hypothesis testing for high-energy physics data using Bayesian methods: Precision calculations are used to determine the likelihood of classifying data as either signal or background. The resulting hypothesis test can have extremely high fidelity, and could be applied to many high-energy physics analyses in the future.
