Organisms interact with environments using their surfaces. I am interested in this interaction between organism and environment in swimming creatures like fish and cetaceans. In particular, I study the microstructure present on the scaled surfaces of different fish species to ask questions about the evolution of scales and potential hydrodynamic impacts of different scales on swimming performance. Below are some images of scales from Osmerus mordax. See blog post on the 3D surface topography method I use here.
