Dr Cohen has a Masters Degree in Clinical Research from Mayo Graduate School and an MBA from Kelley School of Business. His areas of interest include surgical treatment of complex intracranial tumours and vascular lesions. He is a professor at Indiana University Department of Neurosurgery. He is the director of neurosurgical oncology and its fellowship. He is the founder and president of The Neurosurgical Atlas (, a multimedia resource for neurosurgical techniques. His clinical research interests include neurosurgical operative anatomy, innovative operative approaches to deep lesions, and intraoperative fluorescence/mass spectroscopy. His basic science research is focussed on novel drug therapies for glioblastoma. He has published more than 510 publications on the aforementioned topics. Dr Cohen is a member of the American Academy of Neurological Surgery and World Academy of Neurological Surgery. He is also the Associate Editor-in-Chief of the journal Neurosurgical Focus.
Aliasgar Moiyadi

Dr Aliasgar Moiyadi is Professor and presently heads the neurosurgical oncology services at the Tata Memorial Centre (TMC), Mumbai, India. He completed his neurosurgical training from the National Institute of Mental Health and Neurosciences (NIMHANS), Bangalore, a premier neuroscience training institute in India. He was instrumental in establishing the Neurosurgical Oncology services at TMC, one of the few neurosurgical departments in India catering to neuro-oncology exclusively. His areas of interest include novel strategies for improving visualisation and resection of gliomas, particularly navigated ultrasound and optical imaging (which he has pioneered in the country), intraoperative brain mapping including awake surgeries, surgery for eloquent tumours and insular gliomas, minimally invasive neurosurgery, skull base surgery, and biology of malignant brain tumours. Dr Moiyadi has more than 150 peer-reviewed publications and is on the editorial board of many neurosurgical journals, in addition to being the tumour section Editor for World Neurosurgery, one of the leading neurosurgical journals. He is also involved in many clinical trials and translational research projects. He has served as a member of the World Federation of Neurosurgical Societies (WFNS) Technology Committee and the Executive Committee of the Indian Society of Neuro-oncology. He is passionate about teaching and training, especially in the field of neurosurgical oncology. He has a special interest in, and has been at the forefront of educational and training efforts in, the field of intraoperative ultrasound and brain mapping, conducting numerous symposia and hands-on workshops in India and across the world.
Chethan Venkatasubba Rao

Dr Chethan Venkatasubba Rao is the Section Head of Vascular Neurology and Neurocritical Care, the William T Butler Endowed Chair for Distinguished Faculty, Associate Professor of Neurology, Neurosurgery, and Center for Space Medicine at Baylor College of Medicine, and the Medical Director of Stroke and Neurocritical Care ICU at Baylor St Luke’s Medical Center. He is a board-certified neurologist, vascular neurologist, and neurointensivist. Dr Rao obtained his medical degree from the Bangalore Medical College, Bangalore University, did his transitional medicine internship at Henry Ford Hospital in Detroit, his neurology residency and vascular neurology fellowship at Henry Ford Hospital, and a neurocritical care fellowship at Baylor College of Medicine in Houston, Texas.
He has authored or co-authored more than 50 manuscripts in the areas of stroke and critical care neurology and neurosurgery in reputable journals including NEJM, JAMA, Lancet, Neurology, Annals of Emergency Medicine, and Neurocritical Care. He is an ad hoc reviewer for 14 journals including NEJM, Stroke, Neurology, Neurocritical Care, etc. His main areas of clinical and research interest include coma, critical care management of subarachnoid haemorrhage, clinical decision support systems, non-invasive multimodal neuromonitoring, stroke, clot characteristics in acute ischemic stroke, intracranial haemorrhage, cerebral oedema, and outcomes in neurocritical care. He has received funding to study comparative effectiveness methods for evaluating coma outcomes and intracranial non-invasive monitoring of intracranial fluid shifts, and has been funded for studying intracranial fluid shifts in microgravity. He has designed and successfully completed many studies, including award-winning non-invasive monitoring of intracranial fluid shifts during dialysis (ACE-VIPS), and has received recognition for outstanding proposals for research at the Neurocritical Care Research Network conference.
His funding sources include NIH, PCORI, DoD, NASA, and industry. He has served as the chair of the research committee at the Neurocritical Care Society and is the co-lead for Curing Coma Campaign member sites. He has been awarded presidential citations consecutively for 5 years for his contributions to NCS, has received the clinical innovations award, and has been bestowed with the Fellow of Neurocritical Care Society and an endowed chair.
Claude Hemphill

Dr Claude Hemphill is Professor of Neurology and Neurological Surgery at the University of California, San Francisco and Chief of Neurology and Director of Neurocritical Care at Zuckerberg San Francisco General Hospital. His research focusses on advanced neuromonitoring, informatics, and management of intracerebral haemorrhage. He is a founding director and Past-President of the Neurocritical Care Society and is a member of the editorial board of Neurocritical Care. His work has been previously funded by the National Institutes of Health through a K23 Career Development Award to study intracerebral haemorrhage and as PI of the San Francisco hub of the Neurological Emergencies Treatment Trials Network to conduct clinical trials for various neuro-emergencies such as traumatic brain injury, status epilepticus, and stroke. He is the current co-chair of the Neurocritical Care Research Network and of the Curing Coma Campaign of the Neurocritical Care Society. He also served as chair of the writing groups for the 2015 American Heart Association/American Stroke Association Guidelines for the Management of Spontaneous Intracerebral Hemorrhage and the 2018 Clinical Performance Measures for Adults Hospitalized with Intracerebral Hemorrhage.
Francesco DiMeco

Professor Francesco DiMeco is Director of the Department of Neurosurgery at Fondazione Istituto Neurologico C Besta and full Professor of Neurosurgery at University of Milan. Focussing on neurosurgical oncology, he has published more than 190 peer-reviewed papers and several book chapters (h-index: 60, Scopus). He has gained considerable experience in the loco-regional treatment of brain tumours and distinguished himself as a co-author of the first worldwide research that lead to the identification of tumour stem cells in glioblastomas and alternative treatment strategies by inducing tumour cells differentiation, publishing a pioneering article in Nature. Recently, his research has broadened to embrace the field of intraoperative imaging, becoming one of the world’s leaders on intraoperative ultrasound in neurosurgery. Finally, he has founded the first neurosurgical simulation centre in Europe (Besta Neurosurgical Simulation Center) which is also one of the best-equipped simulation centres in the world.
