is a Distinguished Member of Technical Staff at Bell Labs in Murray Hill, NJ.
He received his MSc and PhD degrees in Electrical Engineering from the Swiss
Federal Institute of Technology (ETH), Zurich. In 1987 he founded Audissimo
High-End Audio, a company dedicated to audiophile products. During his PhD
program in 1990, he collaborated with the Biomedical Engineering Lab at the
University of Illinois on noise reduction for hearing aids. In 1993, he joined
Bell Labs to pursue research in speech processing with emphasis on noise
reduction, noise-adaptive compression, and noise estimation. His algorithms
were implemented in a number of Lucent's Echo Canceller and Voice Enhancement
Systems (Cadenza, Symphony, Sonata) as key features of Studio Sound™. As a DSP
expert, he has been engaged in a wide range of fields, including speech coding,
digital control (for optical amplifiers in LambdaXtreme), and video processing.
He collaborated with Alcatel-Lucent’s Enterprise Group in areas of noise
reduction, acoustic echo cancellation, and spatial audio. His current research
interests center on multi-modal spatial audio acquisition and rendering of
uncompromised speech, as well as cloud-based spatial audio processing. Focusing
on the remote participant of a conference, he strives to provide a compelling
auditory experience with detailed spatial resolution combined with a highly
intelligible and pleasing sound quality. He has authored several papers and
holds over fifteen patents.
