Alex is Professor of Marine Science & Technology at the University of Plymouth, and is part of the Marine Physics Research Group (MPRG). His research interests are focussed around suspended particle dynamics, both in terms of how particles (plankton, sediment, bubbles, droplets) behave in a natural, turbulent environment, and also in the use of particles as tracers of turbulent flows. He has developed several in situ optical systems to directly image particles for measurement and identification, and visualise 3D turbulence structure, deploying these on autonomous platforms.
