Personal profile
Research Interests
I am interested in the development and application of computational simulations methods for multi-scale and multi-physics problems in engineering, especially in the areas of fluid dynamics, heat transfer, and material transport. Many of the most fascinating engineering systems are characterized by two or more physical phenomena coupled together in a single domain or across an interface. My research is focused on the development of models for these of these types of problems, and their solution using high performance computing tools. Examples include melting and solidification of metal in advanced manufacturing processes, fluid-structure interaction in the human heart and vascular system, heat transfer in multi-phase flows, and multi-scale transport in environmental systems.
