Biofilm fouling is ubiquitous on ship hulls and other aquatic surfaces, such as corals and soft sediments. However, little is know about the effects of biofilm on boundary layer hydrodynamics. I use high resolution Particle Image Velocimetry (PIV) to image and quantify the flow over biofilms in a high speed flow tunnel. Click to learn more.
Intertidal mudflats are home to a diversity of organisms, many of whom burrow into the sediment for refuge from the elements, to find food, or to escape predation. These burrowing animals are called infauna, and they are considered ecosystem engineers because of the important role they play in coastal systems. Click to learn more.
