Leadership

President & CEO
Ryo Matoba, Ph.D.

Dr. Matoba took his current position in 2010. Under the new leadership, DNA Chip Research Inc. is moving to the next growth phase.

Dr. Matoba was a recipient of JSPS fellowship during his graduate school years in Osaka University. His focus was to develop a method of high throughput DNA sequencing for cancer research. He received his Ph.D. in Physiology in 1993 and joined Research Institute of Innovative Technology for the Earth (RITE), where he worked on genetic engineering of photosynthetic bacteria to improve carbon dioxide fixation. In 1997, he was recruited by Nara Institute of Science and Technology (NAIST) as a Research Associate, and investigated the role of gene expression during brain development. He then moved to National Institute of Health (NIH) as a Research Fellow in 2002. Using his expertise in global gene expression profiling, he dissected gene regulatory networks involved in the maintenance of pluripotency of embryonic stem cells. As he came back to Japan in 2006, he joined DNA Chip Research Inc. as Director of Research and Development Division.

Founder
Kenichi Matsubara, Ph.D.

Dr. Matsubara is a world-renowned genome scientist. He pioneered recombinant DNA technologies in Japan and continues to lead the field of gene network analysis.

Dr. Matsubara received his doctoral degree in Chemical Research from Tokyo University in 1956. He then worked for Kanazawa University as a Research Associate, investigating the mechanism of bacteriophage replication. In 1964, he moved to Kyusyu University and was promoted to Assistant Professor in 1968. During those years, he further developed his expertise in DNA replication and recombination at Harvard and Stanford, and worked for advancement of DNA technologies in Japan. He then took a position of professor at Osaka University in 1975, where he pioneered hepatitis B research and succeeded in vaccine production using yeast system. He also played a pivotal role in Human Genome Project as a founding vice president of the Human Genome Organization (HUGO). He led Japanese team and brought this unprecedented international collaboration project to success. He also focused on profiling temporal and spatial gene expression patterns in human and mouse, developing the first systematic transcriptome analysis method and set up a database "BodyMap". After moving his laboratory to Nara Institute of Science and Technology (NAIST) in 1997, he began to engage himself in developing the latest DNA Chip to accelerate high throughput genome analysis, and served as President and CEO of DNA Chip Research Inc. from 1999 to 2010.
