Affiliation and Research Interests

I am a postdoctoral researcher in the Center for Computational Sciences and Engineering (CCSE) in the Computational Research Division of the Computing Sciences Directorate at the Lawrence Berkeley National Laboratory.

I am currently interested in the development of numerical methods to integrate ODEs. Such equations typically arise when trying to model turbulent flows involving chemical reactions. I am working with the open-source PeleC (compressible) and PeleLM (Low Mach) direct numerical solvers. Within this framework, I am also working on porting the chemistry integration to hybrid CPU/GPU architectures using CUDA. This work is in collaboration with the SUNDIALS group at the LLNL.


Previously

My research interests have always focused on numerical combustion, more precisely on the development of strategies for improving the computational accuracy of numerical simulations involving reacting flows. Before joining the CCSE, I was a postdoctoral researcher at CERFACS (Toulouse, FRANCE) where I was working in the CFD team. I studied the development of reduced chemistries for the combustion in solid rocket motors. I used the chemistry reduction tool YARC developed by Prof. Pepiot. I also worked on the implementation and validation of spray physical models (injection, secondary atomization, wall interactions) in the context of LES. Prior to this, I obtained my PhD from INP Toulouse (FRANCE) in 2017. The main objective was to develop and implement reduced chemistries in a compressible LES code. The information provided enables, in particular, to study critical phenomena such as soot and pollutant formation.

Miscellaneous

I have been a long time user of the chemistry solver CANTERA. I wrote a tutorial for version 2.1 (a few years back) that can still be useful for those that would like to start using this great tool.
