Yew Jin LIM

About

My name is Lim Yew Jin. I am currently a Software Engineer at Google in its Mountain View campus. I received a Bachelors of Mathematics Double Honors Degree in Pure Mathematics and Computer Science (With Distinction) from the University of Waterloo in June 2000. I then returned to Singapore and entered into national service in July 2000. Upon completion of full-time national service in Nov 2002 as a naval officer, I enrolled in the National University of Singapore in Jan 2003 after receiving the A*Star-NUS Graduate Fellowship. I obtained a PhD in Computer Science from the School of Computing, NUS, in September 2007.

My research interests are game AI, interactive media, high performance computing, machine learning.

My resume is available online. Also, check out my blog when you are free.
