Communications and signal processing are enabling technologies of many of today's most important applications. In a diverse and competitive field, my main reseearch interests are in acoustic signal processing, speech processing and audio. Sound is of key importance in everyday life. Being able to capture, process, store and transmit sound has been pivotal to telecommunications and entertainment for many years. One of the new challenges in this growing research field is spatial audo, for which one has to consider not only the sound itself but also the acoustic environment in which the sound exists. This has given rise to many interesting research threads under the general heading of acoustic signal process - meaning the processing of acoustic signals. The tasks of acoustic signal processing include reducing noise from speech, finding the direction of a sound using multiple microphones, and supressing the effects of reverberation. Although I've been working in this field for several years, I'm always amazed that new research questions bubble to the surface, requring new ideas and, eventually, signal processing algorithms to address them.

My most recent research project explores how robot audition can be enhanced using the techniques of acoustic signal processing so as to improve human-robot interactions.
