About me

I am a PhD student in Computer Science at The Fu Foundation School of Engineering and Applied Science, Columbia University in the city of New York. I am also a member of Network Security Lab (NSL). My advisors are Prof. Angelos D. Keromytis and Prof. Steven M. Bellovin.

I received my Master's in Computer Science from New York University in 2013 and B. Eng. Honors in Computer Engineering from Computer Engineering Department, Mahidol University, Thailand in 2010.
