Shinya Maeyama is an assistant professor at the Department of Physics in Nagoya University. He received his Ph.D. degree in 2012 from Tokyo Institute of Technology. Since then he has been engaged in fusion plasma turbulence researches by utilizing gyrokinetic simulations. He has experiences on extension of simulation models, on development of high performance computing techniques, and on analysis of plasma turbulence physics. His current research interests are in multi-scale plasma turbulence including electron and ion scales, where cross-scale interactions between disparate two scales are only resolved in massively parallelized simulations.
