    Background
    I am a researcher at Microsoft Research in Redmond. Before I came to Seattle I got a Ph.D. at the University of Konstanz. Originally I am from Hamburg, a beautiful city in northern Germany.

    2008 – present Researcher, Microsoft Research, Redmond
    2005 – 2008 Ph.D. in Computer and Information Science, University of Konstanz, Germany
    2003 – 2005 Masters in CS, University of Hamburg, Germany
    2000 – 2003 B.Sc. in CS, University of Hamburg, Germany
    Research
    My research is mainly in the area of Computer Graphics, but these days I am also heavily influenced by my great collegues at MSR who work mostly in Computer Vision and on User Experiences. If you look at my publications list below you will see that I have worked on many different topics, but generally I am more interested in pixels than meshes.

    See below for a lists of my publications, and other professional activities.
    Climbing
    While I grew up in a completely flat part of the world, I developed a big passion for climbing Washington's mountains since I got here. The state is just amazing for climbers: within a few hours you can leave your everyday life completely behind and get into vast glaciated landscapes with serious mountaineering objectives. On my climbing page I post a few pictures from recent trips.
