Biography

Dr Loo-Teck Ng obtained her doctoral degree from the University of New South Wales, Australia. She was a Teaching Fellow in the Department of Chemistry whilst pursuing her doctoral degree. She joined UWS in 1985 as an academic and has visited a number of international tertiary institutions and carried out collaborative research projects on polymer chemistry with imminent researchers as reflected in her publications. In recent years, her research interests focus on the in vitro controlled-release of drugs encapsulated in hydrogels synthesized from the photoinitiator-free photopolymerization process as well as nano-encapsulation of drugs and food additives in nanoparticles such as liposomes.
