Research Interests
I perform detailed computations of reactive fluid mechanics in low and high speed flows. I typically address detailed systems of hydrogen-air, as well as hydrocarbons such as methane. Fundamental issues of ignition, extinction, flame stability, flame structure are of importance. I also pay particular interest to the accuracy of the simulation, which requires special computational strategies to capture the multiscale nature of such flow fields. I additionally study the development of rationally reduced models to simulate complex combustion dynamics.

Key Words
Combustion, Flames
