Philipp is now "Doc Bulling"

On Monday, 10th of September 2018, Philipp Bulling sucessfully defended his dissertation on speech enhancement for in-car communication systems. His work focused mainly on the control of adaptive feedback cancellation filters (details can be found here). After an excellent talk Philipp gave very good answers to the questions of the committee and at around 11:30 h everythings war over and we ...
