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.

My research interests evolve around developing numerical tool and using simulations to study the combustion physics. In a broader scope I am interested in computational fluid dynamics. I am currently working on the developement of a strategy for unsteady simulation of low Mach number reacting flows subject to electric fields. The interactions between an external electric field and the charged particles naturally appearing in flames could provide further control on the combustion process, enhancing flame stabilization or reducing pollutant formation.


Previous positions

Before joining the CCSE, I was a postdoctoral researcher at CERFACS (Toulouse, FRANCE) where I was working in the CFD team. My primary focus was on the development of a Large Eddy Simulation (LES) method to enable the simulation of huge industrial flares (~ 10 meters jet flames) in the context of an unstructured/time explicit solver. I also worked in collaboration with Ph.D. students on the analysis of doubly transcritical cryogenic oxygen/methane (LOx/LCH4) combustion.

After completing my Ph.D. from INP Toulouse (FRANCE) in 2015, I joined the Center for Turbulence Research (Stanford, USA) in the group of Prof. M. Ihme. In the framework of the Nat. Jet Fuel Combustion Program, I worked with LES to evaluate fuel effects on the lean blow-out behavior of gas turbines. Fuel sensivity also lead to the investigation of spray combustion, in particular effects arising from the multi-component nature of real fuels.
