Dr Raymond Seet is a Senior Consultant at the Division of Neurology at the National University Hospital, and holds the academic rank of Associate Professor at the Yong Loo Lin School of Medicine, National University of Singapore. After completing his undergraduate and postgraduate training in Singapore, he completed his advanced fellowship in stroke and neurocritical care at the Mayo Clinic, Rochester. He is a Fellow of the Royal College of Physicians (FRCP, Edinburgh) and the Academy of Medicine of Singapore (FAMS).

Dr Seet’s clinical and research interests focus on:

  • Acute reperfusion treatment (intravenous thrombolysis and endovascular therapy) and the neurocritical care of stroke patients
  • Stroke prevention strategies focusing on atrial fibrillation and intracranial stenosis
  • Application of advances in stroke biology and technology to deliver personalised treatment to stroke patients
  • SARS-CoV-2 biology, diagnosis, thrombosis and interventions

Dr Seet has published over 170 international peer-reviewed articles. For his contributions in stroke, he was awarded the Inter-Academy Medical Panel Young Physician Leader Award during the World Health Summit in 2014. The following year, he received the Senior Clinician Scientist Award by the National Medical Research Council, Singapore. He is presently Editor-in-Chief of the Annals of the Academy of Medicine, Singapore, Assistant Editor of Stroke, Chairman of the Chapter of Neurologists, Academy of Medicine, Singapore, and President of the Clinical Neurosciences Society, Singapore. He is also Deputy Chairman of the Domain-Specific Review Board, National Healthcare Group, and Deputy Director of the Healthy Longevity Research Programme at the National University of Singapore.  

Dr Seet contributes actively to medical education and lectures undergraduates, post-graduates and specialists. He has special interest in bedside clinical teaching and clinical assessments. He attended the Harvard Medical International and the Royal College of Physician Programmes for Physician Educators. In 2008 and 2014, he was awarded both the faculty and university awards for teaching excellence (Faculty Teaching Excellence Award and Annual Teaching Excellence Award).
