Fabian Yu Chin Lim

I am currently a Postdoctoral Associate at the Massachusetts Institute of Technology, affiliated with the Integrated Systems Group headed by Prof. Vladimir Stojanovic. I obtained my Ph.D from the University of Hawaii, Manoa, under the supervision of Prof. Aleksandar Kavcic. I was previously a visiting student at the Research Center for Information Security in Japan. I was also a student intern at Hitachi Global Storage Technologies, San Jose. I persued my Masters degree at the National University of Singapore, and at the Data Storage Institute, Singapore, under the supervision of Dr. George Mathew.

Research Interests : error control coding, detection, signal processing
