About me

I got a PhD in Plasma Physics from Paris University in 1998. After 10 years in the United States, where I started as a post-doc at Texas A&M University and ended up as a Research Software Engineer at Harvard University, I moved to the Netherlands to work at KNMI in the 'Chemie & Klimaat' department. My work revolves around computer models of atmospheric chemistry (TM5) and Earth climate (EC-Earth). I participate to the development of these models, make them run faster, and port them to different High Performance Computing platforms. As the leader of the technical working groups for these models, I am responsible for their maintenance and advise the steering committees above them. I also conduct data-intensive experiments with these models, and support KNMI researchers and students.


I have conducted experiments for CMIP6 (Coupled Model Intercomparison Project Phase 6) and participated in various international projects, most recently CRESCENDO, AeroCom, PRIMAVERA, and FORCeS.
