Dr. Lim is a Consultant Neurologist and Professor at the University of Malaya, Kuala Lumpur, where he runs a very busy government clinic and private practice seeing many patients with Parkinson’s disease (PD) and other Movement Disorders, including complicated cases requiring advanced treatments such as deep brain stimulation. Dr. Lim earned his medical and research doctorate degrees from the University of Melbourne and was admitted to Fellowship of the Royal Australasian College of Physicians after completing advanced training in adult Internal Medicine and Neurology in Melbourne. Dr. Lim trained in general neurology and subspecialized in Parkinson’s & Movement Disorders, at world-renowned centres in Melbourne and Toronto (the latter supported by the Edmond J. Safra Fellowship, under Prof. Anthony Lang). He has published widely in the field of Movement Disorders (Parkinson's as well as a variety of rarer movement disorders), with ~200 peer-reviewed journal papers and book chapters, including first-author publications in Lancet Neurology, Archives of Neurology/JAMA Neurology, Movement Disorders, etc. and co-authorship in journals such as Nature Genetics, Nature Reviews Neurology, Annals of Neurology, and Brain (12K citations, h-index 48). He is an Associate Editor for Nature Partner Journal (npj) Parkinson's Disease and Neurology Asia (for several years previously also for Science Advances), and Guest Editor for the Journal of Parkinson's Disease, and is on several Editorial Boards including Parkinsonism & Related Disorders and Neurotorium. Dr. Lim is immediate Past-Chair of the Asian-Oceanian section of the International Parkinson & Movement Disorder Society (MDS) (which has ~3.5K members, from the Clinical and Basic science communities), and serves on several MDS Committees/Task Forces (International Executive Committee [IEC], Evidence-Based Medicine [EBM]; Movement Disorders in Asia; etc.). He is a Steering Committee member, and Co-Lead of the Under-Represented Populations Working Group, of the Global Parkinson's Genetics Program (GP2). He is a holder and/or Reviewer of grants for PD-related funding organisations such as the Michael J. Fox Foundation (MJFF), and the United Kingdom's National Institute for Health and Care Research (NIHR) and Cure Parkinspn's Trust (CPT). With a strong commitment to teaching/training, Dr. Lim has organized numerous teaching courses on Parkinson’s & Movement Disorders, and delivered and/or participated in hundreds of international-level lectures and expert panels throughout Asia-Oceania, North America, and Europe. These have often been under the auspices of the MDS, as MDS Visiting Professor, MDS Ambassador, or MDS Virtual Professor. As a versatile speaker with broad-ranging expertise, he has been invited to give numerous Plenary Lectures, including at the flagship MDS Annual Congress (Toronto 2011, Dublin 2012, Nice 2019, Philadelphia/Virtual 2020, Copenhagen 2023, Honolulu 2025) and at the World Parkinson's Congress (Kyoto 2019). In 2025, together with Profs. Nobutaka Hattori and Pramod Pal, he Chaired a highly successful 9th Asian & Oceanian Parkinson's & Movement Disorders Congress (AOPMC) in Tokyo. He has provided movement disorder fellowship/observership training to neurologists from multiple underserved countries, including Indonesia, Myanmar, Bangladesh, Kyrgyzstan, Uzbekistan, Pakistan, India, the Philippines, and Nigeria, often under the auspices of the MDS (Visiting Trainee Grants or Centre-to-Centre Programs). Dr. Lim is a Medical Advisor to the Malaysian Parkinson’s Disease Association, and a founding member (and Immediate-Past Chair) of the Malaysian Movement Disorder Council. He was elected as a Fellow of the Malaysian Academy of Sciences in 2017. In recognition of his leadership in the Movement Disorders field, he was invited to be an Expert Panelist/Consultant to the World Health Organization (WHO) in 2020 to address global policy, implementation and research related to PD. Dr. Lim's research interests are multi-dimensional, with a focus on the following areas: (i) PD (particularly genetics/genetic epidemiology/genotype-phenotype correlations; evidence-based medicine/clinical trials; non-motor features including gastrointestinal aspects; comorbidities; patient-centred care; and rating scales/disease staging); (ii) Parkinson-plus syndromes and other miscellaneous/"orphan" movement disorders, including progressive supranuclear palsy (PSP).

My research focuses on meteorology (severe weather). I'm also involved with climate and air pollution research. 

Cheong Fei Wen obtained her Bachelor Degree in Biomedical Science (with distinction) from Universiti Malaya (UM), Malaysia. She passed her PhD with distinction and is currently holding the post of senior lecturer in the Department of Parasitology, Faculty of Medicine, UM. Since PhD study, she explored into several malaria-related aspects, including protein expression of the Plasmodium knowlesi merozoite surface proteins; immunogenicity study using animal model; and epitope mapping. Her current research interests include phenotypic and genotypic measures on Plasmodium sp. resistance against anti-malarials, immunogenicity profiling of potential malarial vaccine candidates, and genome engineering in P. knowlesi using CRISPR-Cas9 system. With her deep passion in research, she has been successfully selected and awarded to attend several international workshops/courses including Ungku Omar-Newton Fund Researcher Links Workshop: Neglected Disease in SEA: Building Capacity in Epidemiological Modelling (University of Malaya, Malaysia & Imperial College London, UK) and Wellcome Genome Campus Advanced Course: Malaria Experimental Genetics (WGCAC, UK). She has also obtained and be part of 10 research grants, including UM Research Fund Assistance (BKP), UM Research Excellence Grant (UMREG), Postgraduate Research Fund (PPP), Frontier Research Grant (FRG), Fundamental Research Grant Scheme (FRGS), and Long Term Research Grant Scheme (LRGS), with total amount exceeding RM 2 million. With that, she has published more than 30 articles in ISI-indexed journals.  She is currently the assistant editor of the Journal of Health and Translational Medicine (JUMMEC), associate editor of Asia Pacific Journal of Molecular Biology and Biotechnology (APJMBB), and editorial board member of Tropical Biomedicine. She was the council member for Malaysian Society of Parasitology and Tropical Medicine (MSPTM) in 2019-2020.  She received excellent service certificate and excellent service award, UM in 2019 and 2024, respectively. She has been appointed as Programme Coordinator and assisted the department to develop a new Master by Coursework programme (Master of Medical Parasitology and Entomology, MMPE). She is also the course coordinator for courses in MMPE and Biomedical Science Programme. She is the committee member of Quality Assurance Programme - Quality Committee, Faculty of Medicine (FOM) from 2020. With her interest in academic curriculum, she has also been appointed as Programme Quality Assurance Expert (Pro-QAE) of FOM in 2021, and Pro-QAE of UM in 2024 to assist in programme curriculum related matters.
