Brief Biography (Details in CV)
I absolutely love my hometown, Chiang Mai! I attended Montfort College in Chiang Mai for both my primary and secondary education. Following that, I completed my undergraduate degree at the Department of Mathematics, Faculty of Science, Chiang Mai University in March 2011 (with first class honor). I completed my Master’s Degree in Science (Mathematics) at the Department of Mathematics and Computer Science, Faculty of Science, Chulalongkorn University, in October 2013. At long last, I completed my Doctoral degree in Mathematical Sciences from the Graduate School of Advanced Mathematical Sciences, Meiji University, Japan, in March 2017. I have been working as a lecturer at the Department of Mathematics, Faculty of Science, Chiang Mai University, since July 2017. Recently, in November 2020, I was appointed to the position of assistant professor. I received the Development and Promotion of Science and Technology Talents Project scholarship (DPST) from 2008 to 2017. For additional information, feel free to click on my CV or Research.
I enjoy photography, graphic design, and participating in volunteer activities such as academic camps.
This homepage contains a collection of helpful articles authored by me or curated from various sources. I would be delighted if you find my articles or ideas fascinating. However, it would be greatly appreciated if proper credits or references are given when using the articles I have created.
I’ve been running my personal blog, SnC Spaces (formerly known as Spaces when it was owned by Microsoft), since 2005 in a casual and friendly style in Thai language.
