Skills

Oral communication — Invited seminar at McGill University (February 2026); oral presentation at the Extragalactic Transient Universe Conference (Marseille, July 2025). Scientific writing — First-author manuscript in preparation on Crab pulsar giant pulses; annual activity report writing. Teamwork and collaboration — Active member of three large international collaborations (CHIME/FRB, CHORD, Euclid); research visits to University of Toronto, York University, and McGill University to strengthen ties between Canadian and French working groups. Project management — Independently designed and built a multi-stage data analysis pipeline (cutout extraction, PSF modeling, morphological fitting) deployed on HPC infrastructure, from scratch to operational within a few months. Event organization and leadership — Co-chair of Café-Club at GECO, the weekly seminar series for invited speakers; involvement accounts for approximately 10 hours of organizational work. Chair of the FLAME/FRB Journal Club at GECO, a biweekly meeting dedicated to recent FRB results. Technical and analytical skills — Developed expertise in optical data analysis (SExtractor, PSFEx, GALFIT), HPC workflows, and parallelized Python pipelines; prior grounding in radio astronomy instrumentation through CHIME/FRB telescope service work (two two-week shifts). Commitment to open and ethical science — Completed 23 hours of mandatory doctoral training including "Raising Awareness of Open Science", "Scientific Integrity in Research Professions", and "Research Ethics."
