Dr. Tan Ai Huey is an Associate Professor at the Faculty of Medicine, Universiti Malaya (UM) and Consultant Neurologist and Physician at the Universiti Malaya Medical Centre. As a clinician-scientist, she dedicates her career to excellence in patient care, and medical research and education, particularly in the neurological subspecialty area of Parkinson's disease (PD) and Movement Disorders.

After completing her specialty training in Internal Medicine and subspecialty training in Neurology in 2015, Dr. Tan obtained a PhD degree (with thesis distinction), in which she explored the role of the gut microbiome and novel therapeutic approaches, such as probiotics, in PD. Leading an inter-disciplinary research team at UM, her research has since expanded to genetic and biomarker discoveries in PD and rare movement disorders (e.g., dystonia and ataxia), with the aim to uncover factors that are unique and relevant to the Asian population. Other key research areas include uncovering the impact of geriatric conditions, comorbidities, and non-motor features, as well as understanding patient/caregiver perspectives, in PD. Through collaborations with local and international partners, Dr. Tan and her team work tirelessly to advance personalized, holistic, and patient-centered care in PD and related disorders. Dr. Tan has published extensively in leading medical journals, including first-author publications in Nature Reviews Neurology, Annals of Neurology, Neurology, and Movement Disorders, and co-authorship publications in Lancet Neurology, Nature Genetics, and JAMA Neurology. Her research has received support from renowned funding organizations including the Michael J. Fox Foundation, Aligning Science Across Parkinson's (ASAP) via the Global Parkinson’s Genetic Program (GP2), and the Toray Science Foundation. She currently serves as an Associate Editor for Parkinsonism & Related Disorders, a reputable journal in the field.

Dr. Tan was elected as the President of the Malaysian Society of Neurosciences (MSN) from 2018 to 2022, the professional body that represents Malaysian neurologists and neuroscientists. She currently serves as Honorary Secretary of the MSN Movement Disorder Council, within which she co-authored the National Consensus Treatment Guidelines for PD. She has played key roles in developing the national neurology subspecialty training curriculum. Internationally, she was Treasurer of the ASEAN Neurological Association and has been appointed to Chair several committees of the International Parkinson & Movement Disorder Society (MDS, the peak world body representing clinicians and scientists in the PD/Movement Disorder field), including the MDS Communications Oversight Committee and the MDS Web-based Learning Subcommittee. She is also a Member of the MDS Asian-Oceanian Section Executive Committee and the MDS Evidence-Based Medicine Steering Committee. Grateful for the mentors in her career, she is highly passionate about teaching and believes in developing the next-generation talent in medicine and science, and was twice voted as the Best Clinical Lecturer Award at the UM Faculty of Medicine. Frequently invited as an expert faculty member at various national and international conferences and workshops, Dr. Tan is dedicated to enhancing education and training in PD and movement disorders, especially in underserved regions around the globe, where these efforts can have the most significant impact.
