JAMSTEC > Research Institute for Value-Added-Information Generation (VAiG) > Center for Mathematical Science and Advanced Technology (MAT)

The Center for Mathematical Science and Advanced Technology (MAT) consists of scientists and engineers with a broad set of backgrounds and focuses on multi-disciplinary subjects. The topics we examine range from high performance computing, to stellar objects such as accretion disks, to marine biology related application of graph theory. Furthermore, we intend to apply our knowledge to develop preventive measures to ameliorate the negative effects of natural disasters such as earthquakes and tsunamis.

Our targets include 1) understanding mathematics and physics behind complex phenomena in earth and planetary sciences and biology, 2) develop and conduct large-scale simulation to accurately predict various natural phenomena, 3) aid in the development of advanced technology in marine- and geo-engineering, and 4) feedback of research accomplishments to community and society.

Our fundamental approach is to combine mathematical theories and high technologies to advance the field of biology, marine geology, geophysics and space sciences, thus leading to breakthrough perspectives on these important subjects. The abbreviation "MAT" is also the backronym for "Monster Attack Team", which reflects both the lighthearted side of our team, and the serious side of our work to tame nature's monsters.
