Julian Glatzer

Julian Glatzer is a physicist with a focus on the analysis of petabyte-size datasets and the development of new prototypes. He is a member of the ATLAS collaboration at CERN’s Large Hadron Collider which discovered a new elementary particle, the Higgs boson, in 2013. During his work at ATLAS he became an expert in data analysis, including machine learning methods and distributed computing resources (cloud and grid computing). Julian primarily works with Python and C++ on high-profile physics analyses and has a special interest in mathematical modelling and statistical inference.

Julian is motivated by new challenges and enjoys to familiarize himself with novel technical topics. He appreciates the work in teams that are both diverse culturally and from the professional background of the members.
