Researcher Portfolio

Lim Ser Yong (Dr)
Executive Director
Precision Measurements
Introduction:Joined SIMTech in 1994 after his PhD from USA. Several years of working experience in the industry both in Singapore and USA. Worked for Fairchild Semiconductor as a systems development engineer from 1984 to 1986, and for National Semiconductor as a senior systems development engineer from 1988 to 1989. While studying in the US, also worked as a database system developer for a software company outside Clemson University.

Currently, a group manager responsible for a team of 27 researchers in the research and development of optical and non-optical measurements technology as well as the associated image processing techniques. Also an Adjunct Teaching Fellow with the National University of Singapore and a Supervisory Tutor for the Open University Degree Programme managed by the Singapore Institute of Management.

Provided leadership to several multi-million dollar research projects including the development of a nuclear waste storage inspection system, a ship welding robotic system, and an automated aircraft wing skin inspection system. Now, the project leader for two collaborative research projects with the National University of Singapore, Cranfield University, and Stanford University.
