Professional experiences

since 2018 | Engineer-researcher, expert in high performance computing

CEA

2015-2018

R&D project manager then head of Innovation and Studies division

Adoc Talent Management

I was in charge of study projects (statistical analysis) and software development projects (analysis and data visualization). I hosted trainings for early career stages researchers.

2017-2018

CEO

MindMatcher

I managed this company that is developing tools to collect and analyze data for human resources.

2012-2015

Engineer-researcher, expert in scientific computing

CEA Saclay

I optimized and hybridized a magnetohydrodynamics numerical code used to study turbulence in accretion discs. I realized and analysed a 15 million hours simulation that generated over 10 To of data. I also co-organized a Python training (optimization, parallel computing).

2009-2012

Doctoral researcher, numerical simulations of star formation

UPMC, Laboratoire de Radioastronomie (ENS, LERMA — Observatoire de Paris

I performed numerical simulations, an analytical study and comparisons to observations to study star formation processes.

2009-2012

Project manager for popularization

UPMC

I concieved, organized and evaluated scientific events.

Education

2009-2012

Ph.D. in Astrophysics

Université Pierre et Marie Curie

2006-2009

Magistère in Fundamental Physics and Master in Astronomy & Astrophysics

Université Paris VII — Paris Diderot, Observatoire de Paris
