Special Fields of Knowledge: Computational fluid dynamics; Moving boundaries interacting with flows; Biofluid mechanics; Materials processing.

Present Research Interests: Development of accurate and flexible numerical methods for the simulation of three-dimensional flows in the presence of moving boundaries; broad areas of interest are phase change, multiphase/multimaterial flows and fluid-structure interactions. Applications include: 1. Biomedical flows: white blood cell mechanics, cardiovascular fluid mechanics (plaque growth in arteries, flow in arterial systems, mechanics of heart valves), the mechanics of stomach and intestine. 2. Materials processing: dendritic solidification of materials, interactions of solidification fronts with particles with application to metal-matrix composites and biological material cryopreservation. 3. High-speed flows: projectile impact on materials at high speeds with application to penetration and damage, collapse of voids in energetic materials leading to detonation.
