During the period December 2004 – March 2013 I was the Dean of the School of Engineering Sciences.
I am Vice-President for Faculty Development and Gender Equity of KTH since 2008.
I have worked on modeling and numerical simulation of phenomena involving phase change, fluid flows, heat and mass transfer, surface tension effects, wetting, and other two-phase flows such as electrokinetic separation. At present there is an increasing involvement in micro- fluidics and fluid dynamics in microscopic dimensions. Here, various surface forces, such as surface tension, electrical forces, etc, may dominate. Recently we have analyzed dynamic wetting flows, droplet dynamics, and droplet deposition, as well as electrokinetic flows. There is also a long-standing collaboration with materials scientists, where we have recently studied capillary effects in sintering, and martensitic phase change.
Most of my recent research deals with convective heat and mass transfer phenomena in materials processes of different kinds. It ranges from studying more fundamental aspects of solidification and phase change, to particular processes. In all of these problems convective heat and mass transfer is a key element. I also work on thermocapillary convection, fluid motions induced by surface tension variations over a free surface. This is a common phenomenon in many materials processes, such as crystal growth and welding. I am also involved in work on the growth of individual dendritic crystals, using phase-field simulations. Recently I have 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. I have also done work on rotating flows and two-phase flows.
