Hi there! I have been a research scientist at Google Research since July 2019. I have a broad research interest in theoretical computer science, with emphasis on privacy, approximation algorithms & inapproximability, learning theory and computational social choice.

I received my PhD from UC Berkeley in May 2019, where I was very fortunate to be co-advised by Prof. Luca Trevisan and Prof. Prasad Raghavendra. My PhD thesis focused on hardness of approximation for problems that are neither in P nor is NP-hard; an online copy can be accessed here. I received bachelor's and master's degrees from MIT; there I worked on approximation algorithms for projection games under the wise guidance of Prof. Dana Moshkovitz. Before MIT, I was born and raised in Bangkok, Thailand where I attended Bangkok Christian College.

Acknowledgement. I am grateful to the following people for hosting and mentoring me during research visits over the years: Prof. Yury Makarychev (Summer 2016), Prof. Madhur Tulsiani (Summer 2016), Prof. Irit Dinur (Summer 2017), Prof. Eden Chlamtác (August 2017), Prof. Arnab Bhattacharyya (January 2018), Dr. Kai-Min Chung (December 2018) and Prof. Jarek Byrka (June 2019). I would also like to thank Bank of Thailand for their financial support during my undergraduate study.
