My current research focuses on the effects of turbulence on the vertical transport of suspended sediments in coastal waters. For this, ocean gliders, equipped with optical backscatter sensors and microstructure are the key instrumentation.

Other research topics I work on are the modelling of glider flight dynamics, which is of importance for the processing of raw microstructure data, and the effect of turbulence on the acoustic backscatter intensity from suspended sediment, as recorded by acoustic current Doppler profilers.
