He worked on a readout system for a silicon detector for the ATLAS experiment, then he worked on the Liquid Argon Calorimeter, the High Level Trigger and Data Quality and Monitoring. He also led several efforts on searches for physics beyond the standard model at the LHC,[9][10] in particular searches for doubly charged higgs, extra-dimensions and leptoquarks. He was heavily involved in the exotics physics program at the LHC.
