Hyoungsoo Kim is currently a full professor in the Department of Mechanical Engineering at KAIST. He serves as an Editorial Advisory Board member of Experiments in Fluids. He has a speciality in direct optical measurement techniques, for example 2D/3D Particle Image Velocimetry, interferometric analysis, Schlieren method, and high-speed and fluorescent imaging. Based on the direct optical measurement techniques, he explores fundamental fluid dynamics problems, for instance hydrodynamic instabilities inspired by industry and nature, elastocapillary, interfacial phenomena, complex fluids, elastohydrodynamics motivated by human diseases, aerosols atomization and transportation, liquid and particulates transportation in a porous media.
