I work in experimental particle physics, particularly at the Large Hadron Collider (LHC) at CERN in Geneva, Switzerland. Much of this work is in the context of the CMS Experiment, one of the two multi-purpose experiments at the LHC, along side a collaboration of thousands from around the world.
The Standard Model of particle physics (SM) represents our current understanding of what particles and forces make up the universe. However, there are a number of major issues with the SM that keep it from being an adequate description of the universe. In my research group, we look for evidence of physics beyond the SM that may guide us to a more complete model of the universe. We largely focus on searches for Supersymmetry (SUSY), looking for non-standard signatures where significant discovery potential remains.
This program includes searches that employ novel machine learning techniques to solve high-dimensional kinematic problems, searches for particles that have large resolvable lifetimes, and searches for the heaviest particles that could produced at the LHC. Our group is also involved in the complex systems of electronics used to control and readout the enormous detectors.
