About Me

Hi! My name is Natchaphon (Natch) Ruengsakulrach. I am currently a Master of Engineering in Computer Science student at Cornell University. I enjoy many areas in computer science, especially computer network and security. Outside the realm of computer science, I am interested in business, management, and investment. I am a die-hard Liverpool fan and love writing food reviews on Yelp.
