Stephane Willocq

Professor Stephane Willocq is a faculty member in the Department of Physics at the University of Massachusetts Amherst. He holds a Ph.D. from Tufts University (1992) and specializes in Experimental Particle Physics, focusing on high-energy collider experiments, particularly with the ATLAS detector at CERN's LHC. His research interests include searches for new physics beyond the Standard Model, Higgs boson studies, supersymmetry, and dark matter candidates.

Willocq is deeply involved in the ATLAS collaboration, contributing to analyses of LHC data from Run 2 and beyond. His work encompasses precision measurements of top quark properties, W/Z boson physics, and novel signatures of exotic particles. He has pioneered studies on photonuclear processes in ultra-peripheral collisions and developed advanced data analysis techniques using machine learning.

His recent publications (2024–2025) highlight searches for new scalar particles, vector-like leptons, and long-lived neutral particles, alongside constraints on Higgs boson properties and off-shell behavior. Willocq also contributes to ATLAS computing infrastructure, including cloud resource evaluation and detector calibration improvements.
