Masahide Kashiwagi, Professor
1 student voices
Kashiwagi Lab studies verified numerical computation, which guarantees that the results of numerical computation are correct. The lab works on methods for finding all solutions of multivariable equations, and on interval arithmetic, a way of computing with ranges. It also studies methods for computing solutions of ordinary differential equations with mathematically guaranteed accuracy.

Yasutaka Shimizu, Professor
1 student voices
Shimizu Lab studies problems in finance and insurance using the theory of stochastic processes and statistical analysis. The lab models data that move randomly, such as stock prices, as stochastic processes and mathematically investigates how they work. It also works on statistical methods for estimating future risk from past data, and on calculating the ruin risk of insurance companies. In recent years, it has also put particular effort into developing SEM, a new model for predicting lifespans and mortality rates.

Kenichi Maruno, Professor
1 student voices
The Maruno Lab focuses on nonlinear waves and applied integrable systems. The lab uses mathematics to theoretically analyze complex natural phenomena such as water waves. It also develops numerical computation and simulation techniques for solving nonlinear mathematical models. The lab also hosts lectures and seminars with researchers invited from abroad.

Tsuyoshi Miezaki, Professor
1 student voices
The Saegusaki Lab studies discrete mathematics using algebraic methods. The lab uses algebra to investigate the properties of discrete structures such as those in coding theory, graph theory, and design theory. It also works on finding invariants that completely characterize the properties of graphs and matroids (structures that generalize graphs).

Toru Ohmoto, Professor
0 student voices
Ohmoto Lab studies the properties of singularities that appear in shapes and maps from a mathematical perspective. Singularities are the places where things stop being smooth, such as where a surface folds or has a sharp point, and the lab classifies them using methods from topology and geometry. The research covers a wide range of fields, including persistent homology for studying the shape of data, information geometry related to machine learning, and differential line geometry related to robotics.

Takeshi Ogita, Professor
0 student voices
Ogita Lab mainly studies verified numerical computation. In numerical computation on computers, errors arise from sources such as the rounding of numbers. The lab studies methods that compute while mathematically guaranteeing the bounds within which those errors lie.

Kosuke Kuto, Professor
0 student voices
Kuto Lab uses differential equations to study curious phenomena that appear in living things and materials. Centered on equations called “reaction-diffusion systems,” which describe territorial competition between organisms and pattern formation, the lab theoretically investigates the behavior of their solutions. Pattern formation in chemistry and physics, such as the stripe and spiral patterns formed by molecules moving on a platinum surface, is also a subject of research. The lab values both the appeal of pure theory and the appeal of mathematical models that explain phenomena.

Daisuke Takahashi, Professor
0 student voices
Takahashi Lab studies difference equations and a mathematical technique called ultradiscretization. The lab conducts research using cellular automata, including a model called the "box-ball system," which is described by the movement of balls. The lab publishes its research results through presentations at academic conferences in Japan and abroad, and as papers.

Hiroshi Toyoizumi, Professor
0 student voices
Toyoizumi Lab studies how to represent a wide variety of probabilistic phenomena in the world with mathematical models. It covers a broad range of subjects, including networks, sports, the ecology of living things, genes, financial engineering, and how companies and projects progress. The lab also studies the mathematical properties of probability theory and stochastic process theory themselves, which are needed to understand uncertain phenomena.

Momoko Hayamizu
0 student voices
The Hayamizu Lab uses the language of discrete mathematics to study problems that arise in biology. Centered on the theory of phylogenetic trees and phylogenetic networks, which represent the evolution of living things, the lab works at the intersection of discrete mathematics, statistics, and biology. This work is expected to help explain phenomena that are also medically important, such as cell differentiation and viral mutation.
