My physics interest are primarily electroweak and Higgs physics in the context of model independent searches for effects of high-mass physics beyond the standard model, using the Effective Field Theory approach. I’ve been a member of the CMS collaboration since 2004, when I was working on muon trigger slow control systems as an undergraduate at the University of Florida.
Concerning computing and detectors I’ve recently lead the development and integration of the electron and photon reconstruction used in all CMS analyses for Run 2. I also lead the development of algorithms to reconstruct output of the High-Granularity Calorimeter (HGCal) end-cap upgrade that are operable and yield good physics performance in computationally demanding HL-LHC events with 140-200 overlapping proton-proton collisions (pileup).
For the HL-LHC upgrades I led simulation research that will help determine the functionality of the readout electronics of the HGCal, specifically concerning the reconstruction of time-of-arrival of energy in the calorimeter. This additional information brings the possibility for interesting capabilities, including improved pileup rejection and perhaps a novel implementation of dual readout calorimetry where timing is used to infer energy fractions normally measured through cherenkov emission.
I am also generally very interested in the applications of timing in tracking detectors and calorimeters. I led studies within the CMS experiment that resulted in the proposal and acceptance of a new precision timing detector around the outside of the CMS tracker.
Within the SCD I am part of the newly formed Analysis and Reconstruction group “ARA”. There I am currently researching next-generation tools and techniques for conducting high energy physics analysis at scale through the coffea project (https://github.com/CoffeaTeam/coffea).
