After his Masters degree, Martin moved from native Vienna, Austria to CERN for his PhD work in the ATLAS muon group which he finished in 1999. Following a “fellowship” on numerical field computation and magnet design in the LHC department, he moved back to ATLAS and joined the Liquid Argon (LAr) Calorimeter Group as CERN staff in 2002. Besides his heavy involvement with the calorimeter construction, integration, installation and commissioning, he also served as test beam co-coordinator and worked on electron performance studies and calibration. After two years as ATLAS Run Coordinator and deputy from 2010 to 2012, Martin moved back to the LAr calorimeter group and was elected LAr Project Leader from 2013 to 2019. Besides detector operation, calibration and data quality, the LAr group prepared and started to realise the LAr Phase-I and Phase-II upgrades during that time. From March 2019, he served as ATLAS Deputy Technical coordinator with main focus on preparations for the ATLAS Phase-II upgrade. In parallel, he worked on possible high granularity noble liquid calorimetry for future collider experiments. On 1 March 2024, he began his new role as ATLAS Technical Coordinator.
