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 topic is to develop a hybrid strategy to couple the fully-compressible and the low-Mach-number approaches, based on multigrids and AMR (Adaptive Mesh Refinement) methods. The challenge is to apply such strategy to combustion applications, and more specifically to the study of thermoacoustics problems and combustion instabilities.
