Research interests

My main research interest is in general Underwater Acoustics Systems (Sonar) signal and data processing, with focus on Multibeam echosounders, but also sidescan sonars and sub-bottom profilers. This relates to applications such as:

  • Benthic habitat mapping
  • Seafloor geomorphology
  • Sediment characterization through angular response analysis
  • Coastal sedimentation processes
  • Kelp distribution monitoring

I also apply my interest in Digital Signal Processing to other datat types such as UAV aerial imagery, accelerometers data, current and wind measurements, Lagrangian particle tracking models, etc.

Research grants

  • George Mason Charitable Trust Scholarship 2010.
