Satoru Okamoto is currently a Professor in the Department of Mathematics and Computer Science at Shimane University. He pursued his degree in M.Sc. in 1977 and PhD in mechanical engineering in 1980 from Osaka University. Then, he worked as a researcher in the Research & Development Department at Ishikawajima-Harima Heavy Industries Co., Ltd (IHI). At IHI, he worked as a vendor of aircraft engines and gas turbines, and had also designed compressors and fans of jet engines. He was an associate professor in the Department of Mechanical Engineering at Niihama National College of Technology from 1988 to 1994. Meanwhile, in 1994, he joined Professor Donald Rockwell’s group at Lehigh University as a visiting research scientist for about one year. During this period, he explored an application of flow visualization and PIV in the field of flow-induced vibrations. He is also a member of AIAA and the Japan Society of Mechanical Engineering. His current research interest lies in advanced thermal and fluids science and technology such as flow-induced vibrations, small-scale energy systems with gas turbines and heat pumps, and experimental fluid dynamics and heat transfer. In addition, he has published over 100 journals and conference papers.
