Research

I started as a PhD student in 2011 with Axel Målqvist as my supervisor. My research is about multiscale methods based on the local orthogonal decomposition (LOD) method. I am also interested in partial differential equations (PDEs) with uncertain data. More information about my and related reseach can be found at project homepage multiscale problems and uncertainty quantification.
