Summary
👤
Senior🎓
Top SchoolAndrei Tsaregorodtsev is a Senior Research Engineer with over 25 years of experience building and running distributed computing systems for large-scale particle physics experiments. He co-founded and led the DIRAC project from 2002, evolving it into the production distributed computing infrastructure for the LHCb collaboration and later serving as DIRAC Project Technical Coordinator. Trained as an experimental nuclear physicist (M.Eng. and PhD-level work) from Leningrad institutes, he blends deep domain knowledge of high-energy physics with hands-on backend engineering. Based at CPPM in Marseille since 1998, he continues to drive LHCb computing efforts while contributing code, conflict resolution, and user-focused documentation to the DIRAC open-source repository. His career uniquely spans front-line experimental work at CERN (including L3 and LHCb) through to long-term operational stewardship of a critical grid middleware project. Colleagues rely on him for pragmatic, long-lived solutions that bridge research requirements and production-grade distributed systems.
