Research Interests: Optical Analytical Technologies
Optical sensing technologies have tremendous potential in areas of high socio-economic significance such as in medical diagnostics, environmental and chemical/pharmaceutical process monitoring applications. In the pharmaceutical industry, the recent emphasis on 'quality by design' recognises the importance of Process Analytical Technologies (PAT) for efficient and safe manufacturing of pharmaceutical products. The success of the PAT initiative hinges on the development of robust measurement and interpretation methodologies which can be implemented inline or at-line. In medical diagnostics, a major barrier for physiological monitoring and diagnosis of diseases has been the lack of simple, rapid, and effective screening techniques. There is an acute need for such technologies in situations where rapid analysis and diagnosis may involve decisions under life-threatening circumstances such as natural disasters, and in remote areas where rapid diagnosis are required to combat endemic diseases and epidemics. By providing the ability for rapid measurements and interpretation at an affordable cost, optical sensors operating in the ultraviolet/visible/near-infrared wavelength regions offer great potential for such applications. This research programme is aimed at developing a measurement-interpretation platform that can lead to breakthrough technologies for a range of high-impact problems in process monitoring of chemical and bio particulate systems and medical diagnostics. The programme takes a unique multi-disciplinary approach to these problems by integrating advances in basic technologies for instrumentation with fundamental light propagation theories (physics), inversion methods (mathematics) and multivariate statistical techniques (chemometrics).
