Research Overview
My research focuses on computational multi-fluid dynamics (CMFD) and multi-physics modelling, leveraging advanced numerical techniques such as finite element methods (FEM) and self-adaptive algorithms. I specialise in computational optimisation, predictive modelling—including machine learning and model reduction—and their applications in geophysical systems. My work is driven by a strong interest in addressing challenges in energy technologies, environmental hazards, and engineering systems involving single- and multiphase flows. Through these efforts, I aim to develop innovative solutions that bridge theoretical advancements with real-world applications.
