Lars has been awarded the H.E.S.S. prize for outstanding contributions to characterising the HESS-II instrument and shaping the reconstruction and analysis pipeline of the array. He served as one of the key developers of the H.E.S.S. analysis pipeline HAP, coordinating the implementation and systematic testing. It is to a large extend his achievement that HAP keeps staying one of two competitive analysis frameworks to produce high-impact science results. Lars was also one of the main contributors to an upcoming publication on the performance of the HESS-II array. In this effort, many spin-off developments, from which the whole collaboration benefits every day, were driven by him, including the combined analysis in HAP and a new standard tool for data quality selection.
Besides these activities, he is one of the key persons preparing for the analysis of H.E.S.S. data with open source tools such as gammalib/ctools and gammapy. Accompanying his many technical contributions are numerous analysis tasks which he is actively involved in like the search for Galactic PeVatrons and the discovery of TeV pulsed emission from the Vela pulsar.
