Room  4-4-44

Dr Ng completed his BSc in Monash University. He then pursued his MSc study in University of New South Wales. Later he undertook his PhD study in Neuroscience in the prestigious Neuroscience Research Australia. Dr Ng is actively involved in research and has received several major external research grants (MOSTI eScience Fund, ERGS, FRGS and MTSF Science & Technology grant ). He has a broad interest in research. He is interested in investigating many aspects of the pathophysiology of Parkinson ’s disease. Besides, Dr Ng is also interested in investigating the therapeutic effects of traditional Chinese medicine such as edible bird nest. He is also interested in conducting sleep-related studies (particularly on the physiological roles of melatonin). Dr Ng is the current advisor of Malaysian Parkinson’s Disease Association, and had organized two very successful international conferences 14th APSN Meeting 2016 and MYNEURO 2017 as part of the organizing committee of Malaysian Society of Neurosciences.
