He completed MBBS at Calicut Medical College, MD in General Medicine at Coimbatore Medical College and DM in Neurology at Bombay Hospital. SIMS lists expertise in aneurysm coiling, brain AVM embolization, acute ischaemic stroke intervention and mechanical thrombectomy, together with carotid angioplasty, stenting and cerebral angiography.

His current practice also includes stent-assisted coiling for selected wide-necked aneurysms, cerebral bypass and revascularisation, migraine management, movement disorders and general neurology. SIMS reports that he has performed more than 1,000 neurological and interventional procedures. The hospital also highlights his published work on acute stroke intervention, stent-assisted aneurysm treatment and cerebral revascularisation.

Professional affiliations listed by SIMS include the Indian Medical Association, Indian Association of Neurology and several regional neurological societies. For an international neurovascular opinion, patients should provide brain CT/MRI, angiography studies, discharge summaries, stroke timing, current neurological findings and antiplatelet or anticoagulant medications. Urgency and treatment choice depend strongly on imaging, vessel anatomy and time from symptom onset, particularly in acute stroke, while elective aneurysm or AVM treatment requires detailed individual clinical risk assessment.
