Activities

After several years of experiences in the field of scientific computing applied to various domains such as planetary sciences and oil industry, I joined Cirad in 2016 as a research engineer in computing sciences.

While providing support to researchers working with the Maespa ecophysiology model, I promote at Cirad a management of research softwares allowing the reproductibility of results (in the frame of Open Science) based on Gitlab software repository.

Since May 2023, I am involved in AÏDA research unit for the implementation of the PERSYST modelling platform.

My current activites focus on three axis :

1 – Cirad software repository project management (https://gitlab.cirad.fr)

  • Initiation of a pre-project working group for ressources demand
  • Coordination of the project tasks and comities management
  • Policy of the software projects in the repository
  • Oganization and set up of trainings
  • Set up of a Cirad software community and management of a support network in research units

2 – Animator of the Open Science service for Eco&Sols unit

  • Promoting FAIR principles applied to data and softwares
  • Support to dataset publications in Cirad, INRAE and IRD Dataverse platforms
  • Dataset review before publishing (metadata, licensing, etc .)

3 – Management and developement of the Maespa ecophysiology model (https://eco-sols.gitlab.cirad.fr/maespa)

  • Management of the software project Maespa (https://gitlab.cirad.fr/eco-sols/maespa) and its website
  • Policy of a developement workflow, CI/CD tests and deployment
  • Developement of vizualisation scripts with R markdown
  • Time and memory optimization, porting on HPC platforms
  • Add of scientific features

Projects

  • 2023 – Co-organization of the workshop « Pratiques autour des logiciels de recherche et des forges logicielles » - Cirad, 8th june 2023

Membership

2022 – Invited member of the Working Group « GT2 - Outils et bonnes pratiques techniques et sociales » of the Collège codes sources et logiciels du comité pour la Science Ouverte

2018-2021 – member of the council of Eco&Sols research unit

Since 2019 – Member of the Research Data Alliance

Since 2019 – Animator of the Open Science service at Eco&Sols research unit

Since 2020 – member of the quality service at Eco&Sols research unit
