Biography

My research interests cover a wide range of topics in signal processing, in particular including sensor (antenna, hydrophone, microphone, seismometer, etc.) array signal processing (beamforming, direction of arrival estimation, tracking and localisation), blind signal processing (source separation/extraction), multirate signal processing (filter banks and wavelets), and their various applications, such as wireless communications, satellite navigation, radar, sonar, biomedical engineering, speech enhancement, human computer interface, big data analytics, and renewable energy exploitation.
