Brief Bio

Andrés Bruhn is a professor of computer science at the University of Stuttgart where he heads the department Intelligent Systems at the Institute for Visualization and Interactive Systems (VIS). He received a diploma degree in Computer Engineering from the University of Mannheim, Mannheim, Germany (2001) and a Ph.D. degree in Computer Science from Saarland University, Saarbrücken, Germany (2006). After working as a postdoctoral researcher (2006-2007) he was associated as an assistant professor with the Mathematical Image Analysis Group at Saarland University, Saarbrücken, Germany (2007-2012). During this time he spent two months as a visiting reasearcher at the University of Las Palmas, Gran Canaria, Spain (2009) and built up an independent research group on Vision and Image Processing within the Cluster of Excellence "Multimodal Computing and Interaction" (2010-2012). His research interests include various areas in the field of computer vision and image processing such as motion estimation, stereo reconstruction, image and video enhancement, data compression as well as the design of efficient numerical schemes for many of the aforementioned tasks. In these fields he published over 60 refereed papers with over 3000 citations and an h-index of 22. Prof. Bruhn serves on the programme committee of numereous conferences including ICCV, ECCV, and CVPR and regularly reviews for all major computer vision journals. His publications received several awards, among them the 2004 Longuet-Higgins Best Paper Award of the European Conference on Computer Vision (ECCV), the 2006 Olympus Prize and the 2010 Main Prize of the German Pattern Recognition Society (DAGM), the 2006 Outstanding Dissertation Award of the German Society of Computer Science (GI), the Swiss Computer Science Society (SI), the Austrian Computer Society (OCG) and the German Chapters of the ACM (GChACM) as well as the 2007 Dr. Eduard Martin Prize of the Saarland University. Moreover, he was nominated as one of two national finalists for the 2008 Cor Baayen Award of the European Research Consortium for Informatics and Mathematics (ERCIM).
