Research Overview
My research centers on computational multi-fluid dynamics (CMFD) and multi-physics modeling, employing finite element methods (FEM) and self-adaptive numerical techniques. I specialize in computational optimization, predictive modeling (machine learning and model reduction), and their applications in geophysical models. My primary areas of interest include energy technologies, environmental hazards, and engineering challenges involving single- and multiphase flows.
