Dr. Lam graduated in Mechanical Engineering, Melbourne University in 1979 with first class honours and was awarded the Dixon Scholarship for “Outstanding Academic Achievement”. He obtained his Ph.D. in 1983 from the same University and was awarded the M.H. de Fina Memorial Prize for “The Best Postgraduate Student in the Department”.

Dr. Lam is currently a Professor in the School of Mechanical and Aerospace Engineering (MAE), Nanyang Technological University (NTU). He had held joint appointment as Principal Scientist with SIMTech, and currently a Co-Director of the SIMTech-NTU Joint Lab (Precision Engineering). He was a Fellow of the Singapore-MIT Alliance (SMA) Program. Before joining NTU in 1997, Dr. Lam was a Reader with the Department of Mechanical Engineering, Monash University, Clayton Campus. He was the National President of the Australian Fracture Group; a Director of the Far East Oceanic Fracture Society, Head (Monash Node) of the Co-operative Research Centre of Advanced Composite Structures (CRC-ACS), and was the Program Coordinator for its Tooling and Repair Tasks. He was awarded a plaque by CRC-ACS in 1997 “In Recognition of Service to CRC-ACS”. In 1999, he was invited by the University of Melbourne, Australia to deliver the prestigious Tewksbury Lecture. In 2006, he was invited by Monash University, Australia to deliver the prestigious 2006 Harold Armstrong Memorial Lectures. He was frequently consulted by the industry and had acted as Expert Witness.

    Microfluidic Science & Application, Viscoelasticity, Femtosecond Laser, Biofilm, Micro-molding.
  • Projects:
    Study of Biofilm’s Biophysics in Controlled Environments Using a Microfluidic Platform
    Biofilms are aggregates of bacteria on interfaces and are bound by an extra-cellular polymer matrix. A microfluidic platform capable of exerting well-defined physical and chemical environments for biofilm studies will be developed. The development of such robust platform has the potential to provide a better understanding of the fundamentals of biofilms, from formation, growth to detachment, through the ability to exert controllable environments on the biofilm.

    Electroosmotic Flow Hysteresis
    Electroosmotic flow is the flow of fluid in microfluidic channel under an applied electric field. It has been employed for pumping fluid, mixing and separation of samples/analytes in these micro-devices. The hysteretic behaviors when one fluid displacing another fluid under electroosmotic flow will be investigated. It is a fundamental research on the mechanics of electroosmotic flow; the outcome can potentially be applied to enhance pumping and separation efficiency in microchannel.

    Laser-Materials Interaction
    Laser irradiation is a fast and clean material removal process, capable of highly selective and localized cutting with minimal effect on the bulk material. Laser can also be employed to modify the surface properties of a polymer. Femtosecond laser irradiation has been employed to modify a polymer surface into hydrophilic or superhydrophobic. The laser material interaction inducing the change of wettability is investigated.
