Hanno Ackermann studied Computer Engineering at the University of Mannheim. He received his masters degree (Dipl.-Inf.) in 2003. From 10/2004 until 3/2008 he did his Phd at the University of Okayama, Japan. From 5/2008 until 9/2008 he worked as PostDoc at the Max-Planck-Institute for Computer Science in Saarbruecken, Germany. Since 10/2008 he is a member of the group of Prof. Rosenhahn at Leibniz University Hannover. He is currently funded by a DFG-scholarship (AC 264/2-1).

He is interested in theoretical and practical aspects of supervised and unsupervised learning, segmentation and clustering of data, model and pattern detection as well as model fitting under incomplete and corrupt data.
