Short presentation
I am a professor in scientific computing (numerical analysis) with focus on efficient and reliable numerical methods for time-dependent partial differential equations. Application’s where this is of importance is found in for example quantum mechanics, geoscience and fluid mechanics.

Biography
Born in Stockholm and moved to Uppsala 1992 to study chemistry at Uppsala University. I have M.Sc in astronomy (1996) and finished my Ph.D in scientific computing 2003. My main interest (in science) since 1997 is on efficient finite difference methods for time-dependent PDE. I have previously been employed at Stanford University, Vattenfall and FOI.
In my spare time I like skiing (alpine) or spend time in nature. I have a big interest in food (both making it and eating it) and like to watch science fiction or science programs.
Research
My research has focused on higher order finite difference methods, for computational problems with elements of wave propagation. In recent years, I have especially applied these numerical methods, in collaboration with other researchers, mainly in CFD, geophysics and quantum mechanics. An active project that I am currently working on is calculation methods for low-frequency noise propagation both outdoors and indoors. I have recently become interested in numerical optimization, where you solve a PDE as a constraint.
