Research Topic & Plans for the Future

I am now studying about hypergraph colorings. Here hypergraph is a set together with a collection of its subsets. In detail, hypergraph coloring concerns with how to assign colors to elements of the set so that, in the same subset in the collection, it must have strictly more than 1 color. In particular, I will use topological properties of spaces associated to hypergraphs to find a number of colors which the hypergraph coloring cannot be taken. Thus, I have to acquire a knowledge of topology, which is a motivation for me to study in Department of Mathematices Sciences of this Faculty of Sciences. After acquiring a Ph.D. degree, I have to go back to work in Thailand because I must pay back my scholarship I had received until master degree. However, I will keep on researching and making use of this opportunity of studying in Japan to develop Thailand’s mathematics.

Background to Overseas Study

I got information on this faculty through one of my advisor, Associate Prof. Dai Tamaki. I found that the most detailed and easiest to understand source is my advisor’s homepage when I looked up a notion of a topological invariant. I thought that I may make good progress on topology if I am learned from him. And I got a chance. I was selected by Ministry of Education, Culture, Sports, Sciences and Technology (MEXT) to research and study in Doctoral course in Japan.

Research Topic & Plans for the Future

What I want to study is the field of elementary particles, since I’m always eager to know “the basis” of universe. And personally, I want to see and check those things out by experiments, although I also like to study theories too. If it is possible, I wish to take part in a big projects such as LHC or ILC experiments and want to make a contribution to the development of physics.

Background to Overseas Study

In my high school days, I was very interested in science, especially in the physics, since I had a belief this field will show and teach me every events occurring in the world. Also, I had a strong desire to study abroad, countries like Japan or America that has highly been developed in this field. Luckily, there was a program which Korea and Japan are executing cooperatively, and I was able to join the program. I think this is a very big chance to me to achieve my dream, "learn" and "understand" our universe.
