As an infectious diseases physician, lecturer, and researcher at Universiti Malaya, I focus on advancing research through randomized controlled trials to improve treatment strategies for infections caused by Gram-positive and Gram-negative bacteria. I am dedicated to optimizing antimicrobial therapies in critically ill patients by integrating pharmacokinetics and pharmacodynamics principles to achieve better therapeutic outcomes.

  Dr. Choo currently serves as an Associate Professor in the Department of Chemistry, Faculty of Science, University of Malaya, Malaysia. She obtained her B.Sc. (Hons. Class I) in Chemistry in 1997 and her Ph.D. in Chemistry in 2004 from the University of Malaya, followed by a postdoctoral fellowship at the University of Mississippi, USA. Her international research experience includes visiting scholar appointments at the National Tsinghua University (Taiwan), the IBM Almaden Research Center (USA), and the Institute for Molecular Science (Japan). Dr. Choo’s research focuses on the discovery of bioactive compounds from Malaysia’s ethnomedicinal flora, integrating traditional knowledge with modern drug discovery strategies. She investigates underexplored native species using phytochemical profiling, bioactivity assays, advanced spectroscopic techniques, and computational approaches such as molecular docking, pharmacophore modelling, network pharmacology, and DFT calculations to support target identification, lead prioritisation, and structural elucidation. This integrative framework proved particularly effective during the COVID-19 pandemic in the identification of potential SARS-CoV-2 inhibitors and has since been extended to diverse chemical scaffolds relevant to infectious diseases, oncology, and neuroinflammation. Dr. Choo has published over 100 scientific papers and book chapters and holds an H-index of 24 (Web of Science) and 25 (Scopus). She serves as an Editorial Board Member of Biomedicines and Traditional Medicine Research. In addition to her research activities, Dr. Choo is actively involved in teaching and student mentorship, delivering undergraduate and postgraduate courses in Natural Product Chemistry, Organic Chemistry, and Organic Synthesis, with a strong commitment to developing students’ critical thinking and research capabilities.
