He is the President of the ASEAN Neurological Association (ASNA, 2023-2027), the Chair-elect (2025-2029) and General Secretary (2021-2025) of the Asian and Oceanian Commission, International League Against Epilepsy (ILAE-AO), the chair of the Research Task Force in the commission, the past President of the Malaysian Society of Neurosciences (MSN) and Malaysian Epilepsy Society (PEM), an active member of the Malaysian Epilepsy Council and internationally and ex-chair of the Research Commission in the International Bureau of Epilepsy.

He has been involved in many trials of newer treatments (e.g., newer drugs and transcranial magnetic stimulation) in epilepsy. He also specialises in non-invasive and invasive epilepsy surgery assessment, including long-term video-EEG monitoring, intracranial monitoring with stereo-EEG, subdural and depth electrodes, electrocardiography, and cortical stimulation. Other areas of expertise included vagal nerve stimulation, deep brain stimulation, transcutaneous vagal nerve stimulation, repetitive transcranial magnetic stimulation, transcutaneous direct current stimulation, corpus callosotomy and radiofrequency ablation. 

He is currently the Associate Editor for Neurology Asia, a reviewer for a few academic journals, and an organising committee member of multiple national and international conferences.
