Kenji Mizoguchi is emeritus professor at Tokyo Metropolitan University (TMU), Japan. He joined TMU as professor in the Department of Physics in 1995. He received his PhD from TMU in 1983 on the topic “NMR study on AuV and MoCo dilute magnetic alloys.” Some of his prominent studies are “NMR and ESR study on conducting polymers” (1980), “Electrosodalites, fullerides, molecular charge transfer salts” (2000), and “DNA and metal-DNA composites” (since 2002). He has published nearly 150 research papers so far. His current research interest is in the development of a high-pressure ESR system up to 10 GPa.
