" After several years of experiences in the field of scientific computing, I provide to the modelers of the unit Eco&Sols a support in software development.
My main interest is to improve software codes by implementing new scientific or technical features while enabling collaborative development. I also help researchers to port their codes on suitable computing platforms.
Main activities since my recruitment in 2016 :

- MIN3P reactive transport model : implementation of the root water uptake computation and coupling to root architecture models ArchiSimple and Root Typ
- MAESPA energy partitioning and physiology model : porting on the MBB (Montpellier Bioinformatics Biodiversity) platform for distributed computing, improving the use for specific simulations, profiling and versions comparisons

 In the framework of the Patrimoine Numérique Scientifique mission of the Cirad, my secondary mission consists in promoting Open Science principles at Eco&Sols unit. This challenging task includes support for Eco&Sols staff and administrations of data and software repositories such as:

- Dataverses of Eco&Sols unit at Cirad, IRD and INRA
- Gitlab software forge of Eco&Sols unit "
