Professor A.H.W. Ngan
BSc(Eng)(HK); PhD, DSc (Birm); CEng; CSci; FIMMM; MHKIE
Prof. A.H.W. Ngan studied Mechanical Engineering at the University of Hong Kong and graduated with First Class Honours and as the Williamson Prizeman in 1989. He obtained an S.L. Pao Education Foundation Scholarship and a Croucher Foundation Scholarship to study for Ph.D. in Materials Science at Birmingham University. He took only two years and nine months to complete his thesis, which won the Thomas Turner Research Prize at Birmingham. After spending one year at Oxford University as a Croucher Foundation Research Fellow, he joined the University as a Lecturer in Materials Technology and Solid Mechanics in 1993. He is a Professional Member of the Institute of Materials, a concurrent Professor of Nanjing University and a Visiting Professor of the Central Iron and Steel Research Institute in Beijing.He is a recipient of the Outstanding Young Researcher Award of HKU in 2000-2001, and the Outstanding Researcher Award in 2006-2007. In 2007, he was awarded the Rosehain Medal and Prize by the Institute of Materials, Minerals and Mining, UK, and in 2008, he was conferred a higher doctorate (DSc) by the University of Birmingham. His research interests include the microstructural basis of mechanical properties in metallic materials, dislocation theory, electron microscopy of materials, novel mechanical testing techniques such as nanoindentation, mechanical properties of thin-films, theoretical modelling of material defects including atomistic simulation and dislocation dynamics simulation.
