My research serves engineering science. It aims - based on first principles - at the investigation of causes and the illumination of mechanisms pertaining to systems and processes of engineering interest, thus enabling the determination, prediction and modification of their behaviour. Teaching is in the same spirit and so is the education of the young research collaborators.

My general research area is Computational Transport Phenomena, and mainly Fluid Mechanics, dealing with simultaneous reaction and transport, in transient or steady state, and often in three-dimensional, complicated geometry. The focus is on the effects of viscous and gravitational forces as well as of interfacial and electromagnetic forces, in flow and transport. Among the significant issues related to the effects of the forces, force competition is of primary concern. The realistic and reliable analysis of the problems demand large-scale scientific computing, encompassing state-of-the art methods for discretizing the pertinent partial differential equations, and for the systematic and thorough investigation of the structure of the solution space. The former are based on the Galerkin/finite element method and hybrids; the latter on numerical linear algebra methods which handle efficiently large-scale problems and exploit parallelism in today’s powerful computer architectures. The benefit of interdisciplinarity is utilized in targeting the problems, addressing the important issues and employing the solution methods.
