My name is Masahiro Kojima. I graduated from Kyoto University with a masters degree in applied mathematics and physics in engineering. I joined NASDA (the predecessor to JAXA) in 1979. Since then, I have worked mainly in the field of earth observation.

In 1990, I joined the Tropical Rainfall Measuring Mission (TRMM) Precipitation Radar (PR) instrument development project, and worked on that team until the completion of the PR on-orbit checkout in 1997. After TRMM, I gained additional experience on other satellite development projects, and was mainly responsible for structural, thermal, and power subsystems.

When the JAXA GPM/Dual-frequency Precipitation Radar (DPR) project team was formed on October 1, 2003, I was assigned as the GPM/DPR project manager. Since then, I have been working on the DPR development with my JAXA team members in collaboration with the National Institute of Information and Communications Technology (NICT) organization. NEC Toshiba Space Systems (NTSpace) is the contractor responsible for supporting JAXA and NICT on the DPR development/build.
