Hitoshi Tomaru, Professor
1 student voices
Professor Hitoshi Tomaru's lab studies methane hydrate on the seafloor and the chemistry of water moving underground. Methane hydrate, an ice-like substance containing large amounts of methane, is widespread on the seafloor around Japan. In response to changes in the marine environment such as temperature and pressure, methane hydrate repeatedly forms and decomposes over shorter timescales than other geological phenomena. The lab also uses iodine isotopes dissolved in water to investigate by what paths and over what length of time materials and water move in subduction zones.

Noriyuki Otsubo, Professor

Prof. Otsubo studies number theory.

Jun O'Hara, Professor
0 student voices
Prof. O'Hara studies the shapes of knots and surfaces as maximum and minimum problems in geometry. The professor considers an energy similar to electric repulsion on a knot of string, and searches for the shapes that make it smaller. Möbius geometry, which understands shapes through properties that do not change under inversions in spheres, is also one of the lab's pillars. For general audiences, the work is also introduced as 'how to find the best positions for streetlights in a park.'

Masahiro Futaki, Associate Professor
0 student voices
Prof. Futaki studies homological mirror symmetry. It is a field that uses the language of categories to capture a correspondence in which two seemingly different geometries carry the same information. Its foundation is symplectic geometry, and the approach is more algebraic than that of differential topology. The professor is also interested in applying higher category theory to geometry and mathematical physics.

Fumihiko Sanda, Associate Professor
0 student voices
Prof. Sanda specializes in mathematical physics and differential geometry. In the Department of Mathematics and Mathematical Informatics, the professor belongs to the geometry area.

Yasunori Okada, Professor
0 student voices
Prof. Okada studies algebraic analysis and microlocal analysis. It is a field built on the idea of investigating differential equations using algebraic tools. Microlocal analysis is a method for capturing what kinds of singularities appear in the solutions of an equation, including not only where they occur but also in which direction.

Kazuki Hiroe, Associate Professor
0 student voices
Prof. Hiroe specializes in the theory of algebraic differential equations and representation theory. Recent papers take up topics such as moduli spaces of meromorphic connections on the Riemann sphere, unfolding of irregular singularities, and middle convolution. In the Department of Mathematics and Informatics, the professor belongs to the Fundamental Analysis area.

Masaya Maeda, Professor
0 student voices
Prof. Maeda studies nonlinear partial differential equations. A central theme is whether a wave that travels while keeping its shape (a soliton) remains intact after being perturbed (asymptotic stability). The work deals with equations such as the nonlinear Schrödinger equation and the Klein-Gordon equation.

Hironobu Sasaki, Associate Professor
0 student voices
Prof. Sasaki studies solutions of nonlinear dispersive equations. The subjects are equations that describe waves, such as the nonlinear Schrödinger equation and the Klein-Gordon equation. The professor considers fundamental questions: how long a solution exists and which function it approaches. The professor also works on an inverse problem: finding the unknown nonlinear term from observable scattering data.

Hiroshi Ando, Associate Professor
0 student voices
Prof. Ando studies mathematics, with a focus on the theory of operator algebras. The theory of operator algebras deals with noncommutative objects, in which the order of multiplication cannot be swapped. The keywords of the research are von Neumann algebras and unitary representations, and recent papers also deal with unitary groups of C*-algebras.
