Born in U.C. 0039 at Side 1. He graduated from an Earth Federation comprehensive university and graduate school with degrees in space engineering, nuclear physics, and general astronautics, as well as a license to operate small spacecraft.
Subsequently moving to Side 3, he joined the Zeonic Company and was placed in charge of designing worker machines at the Zeonic Company Development Department . With the formation of the national defense force and the launch of the SUIT Project, he became part of the company's internal project team. He began working on the project as of the MS-02 and, with the development of the MS-05 and MS-06, he was transferred from the company to become a military employee with status equivalent to that of a field officer. As a member of the development staff who could also operate spacecraft, he served as a test pilot for the mobile suits he developed, and even helped write their combat manuals.
As the MS-06R-1 Zaku II High Mobility Test Type and MS-06R-2 Zaku II High Mobility Type models of the MS-06 Zaku II were developed, he participated in their flight testing as well. At this point he was equivalent in status to a Commander. He returned to the Zeonic Company to help develop its second-stage space combat mobile suit, and became a main member of the MS-06R-2P Zaku II High Mobility Test Type development team, but he pursued his own line of research rather than paying attention to the military weapons development that was in progress at the time.
When the war ended, he was in the industrial sector of Side 3's Colony 14. Although he had hoped to stay at Side 3 after the war, he instead returned to Earth at the request of the Federation government, and became an officer of the Federation Forces technical headquarters.
