Dr. Gareth Sim Maw Shin is a senior lecturer in the Department of Pharmaceutical Life Sciences, Faculty of Pharmacy, University of Malaya. He joined in 2017 after completing his PhD in Medical Science at the same university, following a three-year SLAI fellowship under the Ministry of Education Malaysia.

Teaching & Supervision
Dr. Gareth coordinates and delivers key undergraduate courses, including Basic Immunology, Pharmacotherapy for Psychiatric & Neurological Disorders, and Smoking Cessation Programmes. He has supervised 9 PhD and 6 Master’s students to date, with 3 PhD and 1 Master’s graduate successfully completed.

Research Excellence
His research focuses on behavioural science, genetic epidemiology, and psycho- & neuro-pharmacogenomics, with applications in drug abuse, smoking, psychiatric disorders, and ageing. He leads a project on pharmacogenomics of amphetamine-type stimulants and opioid dependence in Malaysia.
He has published over 30 international journal articles and 7 conference proceedings, including in Tier 1 journals such as Brain Research, BBA – General Subjects, Biogerontology, The Pharmacogenomics Journal, and Toxicology. His work advances precision medicine, addiction pharmacotherapy, and public health policy.

Future Directions
Dr. Gareth plans to integrate next-generation sequencing (NGS) and AI models into pharmacogenomics and to pioneer research in ageing genomics and the pharmacogenomics of anti-ageing, addressing the global challenge of healthy longevity.

Impact Summary
With sustained grant success, high-impact publications, international collaboration, and a strong supervision track record, Dr. Gareth is an emerging leader in pharmacogenomics and personalised medicine, poised to translate genomic insights into clinical and public health solutions.
