I am an associate professor in the Department of Computer Science at the Univ. of Salzburg, Austria. Prior to that, I was part of the medical imaging and computer vision group at Kitware Inc., North Carolina, USA. My research spans multiple areas, but mostly focusses on developing machine learning methods that allow to leverage and control structural characteristics of data.
