about me

I am currently a Ph.D. student in Computer Science at The Fu Foundation School of Engineering and Applied Science, Columbia University, in New York. I am a member of Network Security Lab (NSL). My advisor is Prof. Angelos D. Keromytis

I was born in Thailand and won the Royal Thai Government Master's - Ph.D. Scholarship to pursue my education in the United States. I graduated from New York University in 2013 with a Master's in Computer Science.

I earned my B.Eng. in Computer Engineering from Computer Engineering Department, Mahidol University Thailand.
