          Data-processing in LHCb at 30 MHz 35m

          Dorothea vom Bruch is a research scientist with CNRS at the Particle Physics Center in Marseille (CPPM).
          Her main research interests are testing the Standard Model of particle physics with precision measurements, and real-time selection techniques to handle the huge data stream produced by current and future particle physics experiments. She has worked on three different experiments: Pienu (TRIUMF, Canada), Mu3e (PSI, Switzerland) and since 2019 at LHCb (CERN,Switzerland). At the last two experiments, she has developed real-time selection systems processed entirely on GPUs.
