Barbara Hammer is a full Professor for Machine Learning at the CITEC Cluster at Bielefeld University, Germany. She received her Ph.D. in Computer Science in 1999 and her venia legendi (permission to teach) in 2003, both from the University of Osnabrueck, Germany, where she chaired a junior research group on ‘Learning with Neural Methods on Structured Data’.
In 2004, she became Professor for Theoretical Computer Science at Clausthal University of Technology, Germany, before moving to Bielefeld as chair of the Machine Learning group in 2010. Several research stays took her to University Paris I, University of Padova, Birmingham University, and CAIR Bangalore.
Barbara’s research interests cover theory and algorithms in machine learning and neural networks and their application for technical systems and the life sciences, including explainability, learning with drift, nonlinear dimensionality reduction, recursive models, and learning with non-standard data.
