Current interests span advances in underwater acoustics methods for fish stock assessment and improved catch selectivity via the use of scientific echosounders and sonars. Well versed in an experimental approach, both for measurements in situ and ex situ, from ships, probes, moorings to tanks, mesocosms, and sea cages. 

An ecologist by education with diverse experience and a strong background in fisheries acoustics. Previous exposure and involvement with subsea equipment engineering, production and testing, as well as monitoring of seabed gas leaks, underwater imaging, and stereo-photogrammetry.​ I use acoustics to observe a variety of targets found in the water column, chiefly fish and macro-zooplankton (Antarctic and Northern krill, saithe, herring, mackerel, sandeel, cod eggs and larvae, seabed gas bubble leaks, caged salmon, mysids).
