Lim Yau Yan
School of Science
Associate Professor Lim Yau Yan began his academic career as a lecturer in chemistry in 1971 at the University of Malaya after obtaining a PhD in Physical Inorganic Chemistry from the University Of Illinois, Urbana, USA. He retired from University of Malaya in 1998 as a Professor and began his current role at Monash University Malaysia in the same year. Currently he is an Associate Professor teaching Inorganic, Chemistry, Medicinal chemistry and Analytical Chemistry/Spectroscopy at all year levels.
Associate Professor Lim's research interests are diverse, from micellar catalysis based on surface active transition metal complexes to the identification and bioactivity of active compounds from herbal plants
, ,and to studying the effects of processing treatment on the bioactivity of herbal plants. He leads a successful research team consisting of several PhD and Honours students. Since starting work at Monash, ten PhD and one MSc students have successfully graduated with four of them now in academia with independent research careers.
He has been a member of the Review Panel of Malaysian Qualification Agency (MQA) for more than ten years. He has also served as a member of Technical Committee (Chemicals) of Standard Institute Malaysia in 1990’s. Associate Professor Lim is an elected Fellow of the Malaysian Academy of Sciences based on his significant contributions to chemical research and chemistry education.
