Jerry Westerweel is the Fluid Dynamics Chair in the Laboratory for Aero and Hydrodynamics at the Delft University of Technology in the Netherlands. His research interests are turbulence and coherent flow structures, turbulent mixing and chemical reactions, disperse multiphase flows, microfluidics and biological flows, optical measurement techniques for quantitative measurements in flows such as particle image velocimetry, planar laser-induced fluorescence, and holography.
