Yohei Sato works at the Paul Scherrer Institute as a scientist, and at the Swiss Federal Institute of Technology Zurich (ETHZ)  as a lecturer on Computational Multiphase Thermal Fluid Dynamics. He received his bachelor degree from the University of Tokyo in 1995. He worked for Tokio Marine Fire Insurance Co., Ltd. for one year, and then restarted study as a masters student at the Department of Naval Architecture and Ocean Engineering at the University of Tokyo, graduating in 1999. After graduation, he worked for Asahi Glass Co., Ltd. as a research engineer for three years. From 2002 to 2009, he worked for the Center for CFD Research at the National Maritime Research Institute. During this period, he studied as a part-time student on a doctoral course at the University of Tokyo, and received his Ph. D. degree in 2006. Since 2009, he has been working in Paul Scherrer Institute as a scientist. His major research field is Computational Fluid Dynamics, especially for free-surface flows and phase-change phenomena.
