Skills

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 codes by implementing new scientific or technical features while enabling collaborative developpement. I also help researchers to port their codes on suitable computing platforms.

In the framework of the Patrimoine Numérique Scientifique mission of the Cirad, my secondary mission supports the promotion of data preservation by administrating the Eco&Sols Cirad Dataverse.

Main activities since my recruitment in 2016 :

- MIN3P reactive transport model : implementation of the root water uptake computation and coupling to root archirtecture models ArchiSimple and Root Typ

- MAESPA energy partitioning and physiology model : porting on the MBB (Montpellier Bioinformatics Biodiversity) platform for distributed computing, profiling and versions comparisons
