1.  Introduction

Dr Quan graduated from Harbin Institute of Technology (HIT), P. R. China with a BEng in mechanical engineering in 1982. From 1982 to 1985 he worked at the optical instrumentation group, HIT, as a teaching assistant. He received MEng in optical engineering from HIT in 1988. Dr Quan obtained his PhD from Warwick University, UK in 1992. His PhD research involved the quantitative analysis of holographic interferograms using FFT algorithms. Of particular interests were holographic methods leading to automatic analysis of system and application of these methods to surface measurements. Before joining the NUS he worked as a senior engineer at National Measurement Centre, Singapore Productivity and Standards Board.

Dr Quan was appointed as a lecturer at the National University of Singapore in February 1998. He is currently an Assistant Professor at Applied Mechanics Division, Mechanical and Production Engineering Department.
