Born in Kishiwada, Osaka in 1981, Yasuhito Yoshimizu graduated from Seifu High School and received his Master's degree in Materials Science from the Graduate School of Engineering at Osaka Prefecture University in 2005.

He began his career at Toshiba Corporation in 2005, where he joined the Advanced Process Engineering Center of its Semiconductor Company in Yokohama. There, he pioneered the world's first transition to large-diameter wafers for semiconductor wet processes and engaged in collaborative projects with industry leaders such as Sony, NEC, and IBM.

From 2010, he contributed to yield improvement at the Yokkaichi Operations. In 2011, following the Great East Japan Earthquake, he took on-site command to resolve a critical hydrogen peroxide supply disruption, successfully preventing a complete plant shutdown. He then went on to lead the launch of the production process for 3D flash memory starting in 2013.

After the spinoff of Toshiba Memory (now Kioxia), he formulated a 10-year technology and R&D roadmap for devices and R&D from 2017. He was also involved in the rebranding to Kioxia and, from 2019, served as a project manager for organizational culture reform and new business development at the company's research institute.

Through his exploration of new business opportunities, he identified the critical privacy challenges of our data-driven society. This led him to found EmotionX, a privacy cloud service company, in 2025, where he assumed the role of CEO.

Throughout his career, he has been an active presenter at the Japan Society of Applied Physics (JSAP), receiving the JSAP Outstanding Paper Award in 2014. He is heavily involved in academic committees and, since 2022, has held key operational and planning roles in multiple JSAP and IEEE groups, including Vice-Chair of the Division of Nanoscale and Interfacial-Phenomena in Electrochemical Systems.

Yoshihiro Ohba received his Master's degree from the Graduate School of Engineering Science at Osaka University in 1991 and joined Toshiba Corporation in the same year.

Until 2015, he was engaged in research and development for network switches, routers, and network security at the company's Corporate R&D Center and Toshiba America Research, Inc. During this period, he made significant contributions to the international standardization of the Protocol for carrying Authentication for Network Access (PANA, RFC 5191)—now used in Japan's smart meter systems—and IEEE 802.21 (Media Independent Handover Services).

From 2015 to 2019, while at Toshiba Electronics Asia, Toshiba Memory Singapore, and Kioxia Singapore, he led collaborative research projects with Singaporean research institutes on genome analysis and blockchain. Starting in 2019, he led the development of hardware accelerators for confidential computing at Kioxia's Advanced Technology Research Laboratories.

He holds a Ph.D. in Engineering and is an IEEE Fellow. His hobbies include running, mountain climbing, fishing, cycling, stand-up paddleboarding (SUP), and Telemark skiing.
