Implementation of anomaly detection and proactive maintenance solutions for computing cluster management, leveraging large time-series datasets in order to detect early warning signs of potential failures.

• Developement of augmented reality (AR) solution relying on machine learning and computer vision• Data science / Machine learning consultant• Multi language environment (Python, C#, Java) and agile methodology (Scrum, GitLab CI)

HAWC Gamma-ray Observatory: Deployment and operation of the detector, data-analysis and scientific production:• First analyses, detector commissioning.• Make skymaps on a regular basis (Python, C++, statistical analysis).• Astrophysical source catalog: identify known and new sources, characterize them (Bayesian statistics, Python).• Unify data and simulation pipelines. Streamlined pipelines to enable systematic error studies.• Head of the "Data and algorithm" working group.• Computing cluster admin (SLURM batch system, ~2.5k cores, ).• Transition collaboration codebase from Subversion to Git/GitLab (~100 users, ~500k lines of code for main framework, plus other projects).• Organized bootcamps.

HAWC Gamma-ray Observatory: Deployment and operation of the detector, and data-analysis and scientific production:• Work at telescope site: Instrument deployment, calibration, shift (and shift definition). Deployment of refurbished HEGRA CT1 Imaging Air Shower Telescope at HAWC site.• Development of data quality and monitoring tools (Bash, Python, ROOT).• Set up data transfer between site and computing clusters (~5 TB/week).• Documentation review, create missing documentation (e.g. data formats).• Develop event reconstruction and skymap making tools (C++, Python).• Manage HAWC software on the Mexican computing cluster.• Create Mexican analysis meetings.

ANTARES underwater neutrino telescope:• Calibration, operation of ANTARES instrument, shift supervision, work on surface array hardware.• Simulation of the instrument: streamlining "run-by-run" simulation, using instantaneous state of each optical module of the detector, i.e. status, gain, noise rate, etc. This greatly improved the agreement of the simulation with the experimental data. (C++, Bash)• Search for Gamma Ray Bursts (GRBs) using maximum likelihood method. (C++, ROOT)

"Des signaux radio aux rayons cosmiques" ("From radio signals to cosmic rays"): Characterization of the radio emission of cosmic-ray induced extensive air showers, using both experimental and theoretical approaches. At stake, the possibility to use radio arrays as new type of ultra high energy cosmic-ray detectors.Contributions include:• Deployment, calibration, operation of radio and particle detectors (France, Argentina).• Data analysis, simulation (C++, Fortran).• Characterization and modelization of radio emission of cosmic ray induces extensive air showers. Prevailing mechanism = geo-synchrotron.• Simulation of next-gen arrays using acquired knowledge.
