The math of shark skin

Emory math professor Alessandro Veneziani, an expert in fluid dynamics, draws inspiration from nature. The rough surface of shark skin, for instance, helps sharks move faster through the water. Mathematicians have developed an equation for how this roughness translates into less viscosity for a swimming shark. Veneziani has applied this knowledge to everything from swimsuit design to the study of human blood flowing through arteries, to help doctors devise the best strategies for treating aneurisms.
