Dr. Lim Siew Huah is a Senior Lecturer in the Department of Chemistry at the University of Malaya (UM), where she specializes in Natural Products Chemistry and Bioorganic Chemistry. She earned her Ph.D. (2013), M.Sc. (2007), and B.Sc. (Hons.) (2004) from UM, and her research focuses on isolating and studying bioactive compounds from Malaysian plants, particularly alkaloids, for potential applications in health sciences and biotechnology.

Dr. Lim has extensive experience in teaching both undergraduate and postgraduate students and has been actively involved in curriculum development. She teaches courses in organic chemistry and molecular spectroscopy, incorporating contemporary research findings into her teaching. She previously served as the Undergraduate Program Coordinator for the B.Sc. Chemistry program, where she oversaw academic planning and program improvements. In addition to lecturing, she supervises final-year undergraduate research projects (FYP) and mentors MSc and PhD students in organic and natural products chemistry, guiding them in phytochemical investigations and structural elucidation of bioactive compounds.

Her research focuses on natural products chemistry, particularly the isolation, structural elucidation, and spectroscopic characterization of plant-derived secondary metabolites. She specializes in the study of alkaloids, employing advanced spectroscopic techniques such as nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry to determine the structures of complex natural compounds. Her work extends to the chemical modification of natural products to understand their structure-activity relationships and enhance their potential applications.

Her research explores the diverse flora of Malaysia to uncover bioactive natural compounds with potential therapeutic relevance. Investigations include the structural modification of natural products to explore their chemical properties and interactions, particularly in cancer-related studies, skin brightening effects, and other health-related applications. Through her work, she contributes to the advancement of natural products chemistry and its role in biomedical research.
