Brief Biography (Details in CV)

My hometown is Chiang Mai. So I studied on the primary and secondary levels at Montfort College, Chiang Mai. After that, I graduated undergraduate degree from the Department of Mathematics, Faculty of Science, Chiang Mai University in March 2011. I graduated Master’s Degree in Science (Mathematics), Department of Mathematics and Computer Science, Faculty of Science, Chulalongkorn University in October 2013. Finally, I graduated Doctoral degree in Mathematical Sciences from the Graduate School of Advanced Mathematical Sciences, Meiji University, Japan, in March 2017. Currently, I have been a lecturer at the Department of Mathematics, Faculty of Science, Chiang Mai University since July 2017, and an assistant professor since November 2020. I was granted the Development and Promotion of Science and Technology Talents Project scholarship (DPST) from 2008 to 2017. For more details, you can click on my CV or Research.

My hobbies are photography, doing graphic design, and joining volunteer activities (e.g. academic camps).

This homepage stores some useful articles written by me or collect valuable articles. I will be happy if you are interested in my articles or ideas. However, using the articles made by me should give me credits or references.

In an informal way, I have written my personal blog: SnC Spaces (called spaces, when it belonged to Microsoft) since 2005. However, I write in the Thai language.

Research Highlights

My main research interest is related to the mathematical modeling using geometry approaches, especially in the discrete and computational geometry. In addition, I am interested in computational mathematics, and mathematics education.
