Research and Professional Activities

Most of my recent research deals with convective heat and mass transfer phenomena in materials processes of different kinds, ranging from more fundamental aspects of solidification and phase change, to particular processes. I also work on thermocapillary convection, i.e. fluid motions induced by surface tension variations over a free surface. I have recently begun to work on dielectrophoretic separation in micro-flows. I have also developed symbolic computation tools to generate finite element code for general systems of partial differential equations, which are used to simulate problems in the areas above.
