Christian Schellewald
Om
I received my Ph.D. degree from the Department of Mathematics and Computer Science, University of Mannheim, Germany. Then I was a Marie Curie Postdoctoral Researcher in the School of Computing, Dublin City University (DCU), Dublin, Ireland. In 2009, I became a Postdoctoral Researcher at Norwegian University of Science and Technology (NTNU), Norway, and was supported by an Alain Bensoussan fellowship from the European Research Consortium for Informatics and Mathematics (ERCIM). Between 2012 and 2016 I was employed as Associate Professor at NTNU doing research and teaching. Currently I am working at SINTEF Ocean. My research interests include mathematical and applied problems that arise in the field of computer vision with particular focus in mathematical optimization and convex programming, statistical object and pattern recognition, symmetry detection, segmentation, classification, and 3-D reconstruction methods.
