I’m an experimental particle physicist searching for new phenomena beyond the Standard Model. My work is centered at the Large Hadron Collider in Geneva, Switzerland, where I worked first with the ATLAS Experiment, and now with the CMS Experiment. I work collaboratively with thousands of physicists around the globe to build and operate massive particle detectors, and lead smaller teams to use their data to search for new particles.
My expertise is in searching for Supersymmetry, and in particular, scenarios in which particles acquire macroscopic lifetimes, producing exotic signatures which would evade standard search methods. I also work in hardware-based pattern recognition, focusing on tracking particles at high enough rates to use this information in real time analysis.
