Research

The Large Hadron Collider (LHC) has thrust us into the precision realm of collider physics with its triumphant victory in achieving extraordinary accuracy in the measurement of key fundamental parameters of the Standard Model (SM). The electroweak sector of the SM, specifically the non-Abelian gauge structure, predicts the production of multiple gauge bosons in a single LHC collision event. My primary research interests lie in studying triboson and vector boson scattering processes. Both of these have only recently been observed given their low production probabilities; however, as the LHC collects more data, characterizing these processes will become integral to the precision program of collider physics. Continuing my studies in the electroweak sector, I am focused on elucidating the role of the Higgs boson in unitarizing the scattering of longitudinally polarized W-bosons.

The second thrust of my research is to benchmark and develop event generator workflows in ATLAS using state-of-the-art, GPU-enabled versions of widely used generators. Event generation is the crucial first step in any simulation workflow. In order to facilitate the precision era of collider physics, significantly greater computational resources will be necessary to implement event generation at higher accuracy. The GPU-enabled versions of these generators are highly performant, demonstrating improvements of up to an order of magnitude in computational time.

A third thrust of my research is to study the efficacy of machine learning-based inference at the global trigger as part of the upgraded ATLAS detector.
