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.
