Prof of Statistical Signal Processing

Research interests

  • Paul has research interests which include signal processing, underwater acoustics and bioacoustics (the way animals, especially marine mammals, use sound). He is primarily concerned with developing tools to assist in the computer-aided analysis of underwater sounds and understanding the role of those sounds in the marine environment.
  • Acoustics, in the form of sonar, is an important tool for the exploration of the marine environment. It is used by the seismic industry to locate oil and gas reserves, by the military to detect objects, by oceanographers to make measurements and by marine mammals to survive.
  • Man-made underwater acoustic systems rely upon computers to process the data coming from sensors to interpret the environment. The processing methods within the computer systems are a critical component often defining the overall success of the instrument.
