Hyoungsoo Kim is currently working at Howard Stone's lab of Princeton University as a Postdoctoral research associate. He has a speciality in Particle Image Velocimetry with microfluidics flow. Furthermore, based on the PIV measurement technique, he is trying to understand hydrodynamics instabilities, elastocapillary, microfluidics, and fundamental fluid dynamics problems. He received his Ph.D. degree in Department of Mechanical, Marine, and Material science (3mE), Delft University of Technology (TUDelft), the Netherlands. His thesis is about investigating complex flow pattern inside detwetting corner flow by using tomographic Particle Image Velocimetry and 3D Particle Tracking Velocimetry. The project is based on the industrial application from ASML, the Netherlands. During Ph.D. course, Hyoungsoo was supervised by Prof. dr. ir. Jerry Westerweel at the Laboratory for Aero- and Hydrodynamics. In 2012, he worked as a visiting researcher in the lab of Prof. Ho-Young Kim at Seoul National University (SNU), Seoul, Republic of Korea. He received his M.S. degree in School of Mechanical, Aerospace and Systems Engineering in Division of Mechanical Engineering at Korea Advanced Institute of Science and Technology (KAIST), Daejeon, South Korea. His MS thesis was selected as a 2007 Outstanding dissertation award for BK21, KAIST. He received a Summa Cum Laude when he graduated from Kumoh National Institute of Technology (kit) for a B.S. degree, Gyeongbuk, Gumi, South Korea.
