Position:    Former Assistant Professor E-mail: setzer -at- mia.uni-saarland.de (please replace anti-spam -at- by @)

In 2006, I received my diploma in mathematics and computer science at the University of Mannheim, Germany. During my diploma studies, I spend one year at the University of Waterloo, Canada. I defended my Ph.D. thesis in December 2009 at the University of Mannheim. My advisor was Prof. Gabriele Steidl.
From January 2010 to July 2010, I was a research visitor funded by the German Academic Exchange Program DAAD at the group of Prof. Stanley Osher at the University of California, Los Angeles.
Since September 2010, I am a member of the Mathematical Image Analysis Group at the Saarland University.

My research is focused on optimization methods for problems which arise in image processing, computer vision and machine learning. Google scholar profile.
