Biography

Dr. Kazuya Tajiri earned his Bachelor degree from the University of Tokyo, and Master of Science degree from Georgia Institute of Technology in the field of turbulent combustion simulation. After three years of fuel cell research at Nissan Motors in Japan, he returned to the U.S. to continue PhD research at Pennsylvania State University, and earned his PhD degree in 2008. After two years of experience at Argonne National Laboratory conducting fuel cell systems modeling and analysis, he joined Michigan Technological University in 2010.

Currently, Dr. Tajiri is the director of the Multiscale Transport Process Laboratory (MTPL), and investigates the multiphase, multiscale transport phenomena in energy conversion devices and propulsion systems.

At present, two main research objectives are being conducted:

Electrochemical devices for energy conversion
Unsteady flow systems for propulsion / energy conversion
