Hitoshi OHSATO is a Senior Researcher at Nagoya Industrial Science Research Institute (NISRI), Japan, and a visiting Professor at University of Oulu. He received a Dr. of Science from The University of Tokyo in 1984, and a Ms. of Engineering from Nagoya Institute of Technology (NIT) in 1970. He studied at the NIT from 1970 to 2008 as a professor. After retirement in 2008, he joined NISRI and Hoseo University in Korea as Brain-Korea Program Professor from 2009 to 2012. He also studied as a Visiting Scholar in Center for Quantum Device, Northwestern University (Illinois, USA, 1993-1994). His main scientific interests are microwave dielectrics, ferroelectrics and piezoelectrics. He organized the 3rd International Microwave Materials and their Applications (MMA2004) at Inuyama, Japan. His research has been studied consistently electroceramics based on the crystallography. He has published over 280 papers and 14 books, and has filed about 30 patents, which are cited more than 7000 times by the Research Gate. He has received prestigious awards, including: the 59th Ceramic Society of Japan Award for Academic Achievements (2005); the 1st Okazaki Memorial Award (2007) from the Fulrath Okazaki Memorial Association; and the Applied Mineralogical Science Award (2017) of the Japan Association of Mineralogical Sciences for practices of the development of electroceramics based on applied mineralogy. And he was elevated to Fellow of American Ceramic Society in 2016 Annual Honors and Awards Banquet, and he got NOKIA FOUNDATION for Nokia Visiting Professor of the University of Oulu in 2016. He organized many projects including: Regional New Development Consortium Project by METI (2002-2003) and NEDO (2005-2007). After retirement from NIT, he has been studying Indialite/Cordierite glass ceramics for millimeter-wave dielectrics as one of researchers in Hoseo University in Korea (2009 to 2012), and he is researching LTCC applied the glass ceramics under Professor Heli Jantunen and Dr. Mailadil Sebastian in Microelectronics Research Unit in University of Oulu in Finland (2016 to 2019).
