Under UK-India Education & Research Initiative, he has established the largest blood bio-repository of stroke in India, in collaboration with Imperial College, London, UK.  He has been the national Coordinator of many International Stroke Trials viz. IST, STICH, ENOS etc. His Cochrane review of Surgery in Intracerebral hemorrhage was first to establish the role of surgery in the condition.

He is Chairman of the Scientific Advisory Board, Panel Area for Stroke Registry, Indian Council of Medical Research, and has been the Convenor of the National Stroke Management Guidelines (India).  

Dr. Prasad coordinated the first multicentric national randomized study of role of bone marrow derived stem cell therapy in stroke, which is first of its kind study at global level published in the American Stroke Association Journal ‘Stroke’. He has also conducted a research trial on Mobilization of Stem Cells Using G-CSF for Acute Ischemic Stroke published in international journal “Stroke Research & Treatment”. He is also coordinating a project in which role of biomarkers for the prediction of stroke recovery is being studied. He has been the principal investigator of several stem cell studies in stroke model and genetics of stroke funded by Government of India. 

Dr. Prasad has also made outstanding contributions in the field of Evidence-Based Medicine (EBM). He has been associated with EBM since its inception 1992. He has received master degree in health research methodology and clinical epidemiology with emphasis on EBM from the McMaster University, Canada in 1993.  He has worked with and is part of the First (pioneer) International Working Group on EBM established at McMaster. He has contributed three chapters as a co-author in the world famous JAMA (Journal of American Medical Association) Book on “Users’ Guide to Medical Literature” published by McGraw-Hill. He has conducted several workshops on Research Methodology and Evidence Based Medicine in India and abroad. He is the founding Secretary of the International Society for Evidence-Based Health care. He is also Chairman of the research methodology courses for UG/PG students being conducted at AIIMS, New Delhi. 

He has authored a book “Fundamentals of Evidence-Based Medicine”, which has been reviewed as the best recommended book in the field by the Journal of American Medical Association in December 2006. He has been the Editor-in-Chief of “Bickerstaff’s Neurological Examination in Clinical Practice”, 7th edn. He has also authored a Book on Stem Cell in Hindi titled “Stem Cell – Sankshep me sabhi aavashyak jaankari” for general public.   

Dr. Prasad is a Fellow of Royal College of Physicians (Edinburgh), Fellow of National Academy of Medical Sciences (India), and Editor of Edinburgh-based Cochrane Stroke Group. He has also received several awards and honours from national and international organizations including the prestigious civilian honour “Padmashree” from the President of India. 

He has also been Chief Guide to several UG/PG and Ph.D. students (currently 8). Presently, he is working in the area of Stem Cell transplantation in Multiple sclerosis and Stroke.
