Outline of research activitiesI am studying physics using mathematics (differential geometry and differential topology). My special interest is in elementary particles theory, general relativity, and relativistic cosmology. I am also studying nonlinear science.
Determinism and probability theory have been widely and successfully used in explaining natural phenomena. However, the two do not hold together at the same time. To solve this discrepancy, I aim to study nonlinear differential equations theoretically by applying the dynamical systems theory to them and construct a large-scale theory that simultaneously uses both determinism and probability theory. In the elementary particles theory, superstring theory is considered the only theory. I am particularly interested in topological field theory and superstring theory and would like to include them in my research.

Outline of research activitiesA subject of my research in the cryptographic theory is development of new cryptographic system which prevents attacks of quantum computer which has potential to grow up into big threat. Its security analysis in theoretical and experimental manner is also important, therefore, for multivariate public-key cryptography in particular, I hold a cryptography solving contest, MQ challenge, as one of organizers, and the contest is released to public on a website as follows.
I also study not only simple cryptography with normal function, and also cryptography with high-function like keeping addition in the encrypted world.
A subject of my research in the number theory is the automorphic representation which is related to unsolved problems, Langland conjecture and Arthur conjecture.- Desired cooperation

Outline of research activitiesMy research interests are in the origin and evolution of life on Earth in the 4.6 billion-years geological records; particularly the evolution of eukaryotes and multicellular animals. I am trying to clarify the environmental changes across these evolutions, based on the geological fieldworks in UK, China, Gabon, Mongolia, etc., the stratigraphic reconstructions (lithogy, fossils, age determination), and the paleoenvironmental reconstructions (chemical analyes). I am also developing teaching materials for geoscience education using VR technology.

Outline of research activitiesI am interested in a quantum spin system where nontrivial magnetic ground states appear. To investigate those experimentally, vaious methods are utilized from static and dyanmic points of view.
By reducing the system saize some materials is weakening , and another is strengthening in magnetic properties. To learn more about the origins of those, I am conducting magnetic measurements with high sensitivity.
Experimetnal studies on hydrogen-induced phenomena are also one of my essential research activities. Also, I am carrying out the development of a new method to evaluate hydrogen absorption properties aiming at high-performance hydrogen strage.- Desired cooperation

Outline of research activitiesI have wide experience in teaching English in several types of schools such as junior high and high schools, including a correspondence course high school, and a university. So, in the field of English Language Education, I am interested in how to improve English language skills of EFL learners at each stage of language learning and lead them to be self-disciplined learners from the viewpoint of SLA.
In one case, learners at the higher education, e.g. university students, are required to read several literatures in order to gather information or knowledge on their interest. Some literatures may be written in Japanese, but in most cases, they are written in other languages, including English. I am investigating some possible aspects related to their effective reading, such as formal instruction, vocabulary building, background knowledge etc., and would like to identify aspects effective to reading for information gathering. These aspects may vary according to learner characteristics. In another case, I am performing studies of effective use of media such as music and movie in the language classroom.
Moreover, I would like to investigate the potentiality of BASIC English, which was “discovered” by Charles Kay Ogden, and develop educational materials for EFL/ESL Learners based on Ogden’s idea shown in BASIC English. BASIC English is a simplified and organized English brought up by Charles Kay Ogden as an international auxiliary language, and as an aid for teaching English as a second language. I think his idea is still very significant even today.- Desired cooperation

- Representation theory of commutative algebras
Outline of research activitiesI specialize in representation of commutative algebras. Commutative algebras were initiated to give us the basic frameworks of algebraic geometry, invariant theory and number theory. Afterwards, it gained its own problem awareness and has become one of the research fields of mathematics. Nowadays, it has closed ties to various fields and has actively been researched.
As one of the research purposes, representation theory of commutative algebras aims at understanding the structure of the category of modules over a commutative ring and the derived category and e.t.c..
Now I am interested in representation theory of commutative dg algebras and will study it.- Desired cooperation

Outline of research activitiesI am studying the images and movements of the learners in dance, and the teaching methods that elicited physical expression.
I am studying the image and movement in dance, such as what kind of image the learner perceives and what kind of movement appears,toward the realization of creative physical expression.
I would like to develop learning and teaching methods through exercise and sports, including dance.- Desired cooperation
