I am a software engineer at Google Japan. I work on Google Maps.

I earned my Ph.D. in Computer Science in May 2017 from Cornell University where I was privileged to be advised by Kavita Bala and Steve Marschner. I did research on rendering algorithms and appearance acquisition/modeling, specializing in problems related to fibrous materials such as human hair and cloth.

Before coming to Cornell, I lectured at Department of Computer Science, Faculty of Science, Kasetsart University. I finished my undergrad at Massachusetts Institute of Technology and also got a master's degree there.

Apart from my specialty in computer graphics, I'm broadly interested in computer vision, machine learning, computational social science, algorithms, and mathematics.

My Erdős number is at most 4. (Khungurn - Saranurak - Nanongkai - Tetali - Erdős)

I have studied Japanese for 6 years: 3 years in college and 3 more years here at Cornell. I can hold conversations, explain rather complicated concepts, and write essays. As for formal qualifications, I passed the JLPT N2 in December 2015.

I'm deeply interested in Japanese pop culture such as anime, manga, and video games. (Yes, these are what I have been studying Japanese for!) When possible, I blend these interests with my academic interests. That is why I studied computer graphics for my Ph.D. and why I did a machine learning project on anime/manga images.
