### ABOUT AMS

The essence of science is to derive principles from observations, thus
revealing simple structures behind what appears to be a complex
phenomenon. Mathematical sciences, in particular, use mathematical
approaches to investigate "mathematical models", which are derived
experimentally. The modern frontier of mathematical sciences considers
various new mathematical models including those for biological and
social phenomena, in addition to more traditional ones in natural
sciences. These models are investigated through analytical approaches
as well as numerical simulations for understanding of the
phenomena. The knowledge thus obtained is employed to develop
innovative technologies or to predict the future, while new
methodologies are devised for deeper understanding of phenomena.
Our department pays particular attention to large scale and/or highly
non-linear complex phenomena in its research and
education. Particularly in education, we aim at providing students
with both scientific viewpoints which help them understand principles
as well as engineering viewpoints which are useful in solving real
problems in manufacturing. These double viewpoints will give students
comprehensive perspectives over science and engineering in
mathematical sciences. We look forward to ambitious applicants
interested in advanced mathematical sciences.

### Division of Applied Mathematical Sciences

Computer simulations provide powerful means of solving various problems in science and engineering.
Computational mechanics is one of such approaches which, along with theoretical and experimental mechanics, investigates mechanical phenomena efficiently. This division develops various approaches of the Boundary Integral Equation Method (BIEM), which is one of major techniques of computational mechanics and is considered suitable for the analyses of phenomena such as waves, fracture, etc. We are currently interested in fast BIEMs and their applications to large scale problems.

Assistant Professor

Micro and Nano Flows, Kinetic Theory of Gases, Non-equilibrium Phenomena

Our main research interest is to clarify the behavior of non-equilibrium gas flows and to establish theories to describe them. Through theoretical and/or computational investigations applied to kinetic equations, describing the statistical behavior of many particles, we elaborate new continuum theories applicable to non-equilibrium flows. We also derive and construct related mathematical models for non-equilibrium flows and clarify the relations between various fluid models.
