Walter Kellermann received the Dipl.-Ing. (univ.) degree in electrical engineering from the University of Erlangen-Nuremberg, Erlangen, Germany, in 1983, and the Dr.-Ing. degree from the Technical University Darmstadt, Darmstadt, Germany, in 1988.
From 1989 to 1990, he was a Postdoctoral Member of Technical Staff at the Center for Information Principles Research of AT&T Bell Laboratories, Murray Hill, NJ. In 1990, he joined Philips Kommunikations Industrie, Nuremberg, Germany, to work on hands-free communication in cars.
From 1993 to 1999, he was a Professor at the Fachhochschule Regensburg, where he also became Director of the Institute of Applied Research in 1997.
In 1999, he cofounded DSP Solutions, a consulting firm in digital signal processing, and he joined the University Erlangen-Nuremberg as a Professor and Head of the Audio Research Laboratory. He authored or coauthored 16 book chapters, 250+ refereed papers in journals and conference proceedings, as well as 50+ patents, and is a co-recipient of nine best paper awards.
His current research interests include speech signal processing, array signal processing, adaptive filtering, and its applications to acoustic human–machine interfaces. Dr. Kellermann served as an Associate Editor and Guest Editor to various journals, including the IEEE Transactions on Speech and Audio Processing from 2000 to 2004, the IEEE Signal Processing Magazine in 2015, and presently serves as Associate Editor to the EURASIP Journal on Applied Signal Processing. He was the General Chair of seven mostly IEEE-sponsored workshops and conferences. He served as a Distinguished Lecturer of the IEEE Signal Processing Society (SPS) from 2007 to 2008. He was the Chair of the IEEE SPS Technical Committee for Audio and Acoustic Signal Processing from 2008 to 2010, a Member of the IEEE James L. Flanagan Award Committee from 2011 to 2014, a Member of the SPS Board of Governors (2013-2015), and is currently Vice President Technical Directions of the IEEE Signal Processing Society (2016-2018).
He was awarded the Julius von Haast Fellowship by the Royal Society of New Zealand in 2012 and the Group Technical Achievement Award of the European Association for Signal Processing (EURASIP) in 2015. He is an IEEE Fellow.
He is currently a Visiting Fellow at ANU.
