Keynote Speaker Biographies


Dr. Greer’s research interests include predicting recovery from coma after cardiac arrest, brain death, and multiple stroke-related topics, including acute stroke treatment and stroke prevention. He is a leader in the Neurocritical Care Society, the Society of Critical Care Medicine, and the American Stroke Association. Additionally, he is a well-regarded and dedicated medical educator and clinician.

Dr. Greer is the editor-in-chief of both Neurocritical Care Live and Seminars in Neurology. He serves as a reviewer for several journals, including the New England Journal of Medicine, Annals of Internal Medicine, Brain, Neurology, and Stroke. He is a fellow of the Society of Critical Care Medicine, American Academy of Neurology, American Heart Association, American Neurological Association and Neurocritical Care Society. He has authored more than 150 peer-reviewed manuscripts, reviews, chapters, guidelines, and books.




Thanh N. Nguyen, MD, FRCP, FSVIN, FAHA, is a neurologist and Director of Interventional Neurology/ Neuroradiology at Boston Medical Center (BMC). Dr. Nguyen is also a Professor of Neurology, Neurosurgery and Radiology at Boston University Chobanian & Avedisian School of Medicine. She is currently President of the Society of Vascular and Interventional Neurology, the first woman in its 17-year history. 

Her clinical and research interests include acute intra-arterial therapies for stroke and brain aneurysm endovascular treatments. An expert in interventional neuroradiology (INR), Dr. Nguyen has been involved in more than 3,000 INR procedures, including more than 500 brain aneurysm interventions and 400 acute stroke interventions. Dr. Nguyen has authored more than 360 publications, contributed to national guideline statements and book chapters, and is Associate Editor of the Stroke Journal.





Christopher Ogilvy, MD is the Director, Endovascular and Operative Neurovascular Surgery, BIDMC Brain Aneurysm Institute, and Professor of Neurosurgery, Harvard Medical School. Dr. Ogilvy is known nationally and internationally for his work in neurointerventional and operative procedures, and has been a moving force in the field of neurovascular disease for the last twenty years. 

Dr. Ogilvy’s research and academic endeavors are in the areas of neurovascular disease, including intracranial aneurysms, arteriovenous malformations and atherosclerotic disease. Much of his work has been focused on studying outcomes of operative and endovascular procedures. In the laboratory, efforts have been focused on studying cerebral ischemia in the setting of neurovascular procedures, with a recent focus on the biology of intracranial aneurysms and the use of tissue engineering techniques to treat saccular intracranial aneurysms. He has pioneered several techniques in surgical procedures and is pursuing avenues of research in clinical treatment of patients with intracranial vascular problems using endovascular techniques. 

Dr. Ogilvy is past President of the New England Neurosurgical Society and has served on numerous national neurosurgical committees.  He is the Medical Director of the Brain Aneurysm Foundation, a national organization to help patients and families with brain aneurysms and to fund clinical and basic research. He is an Associate Editor for the journal Neurosurgery. He has published extensively, with over 400 original manuscripts and over 100 book chapters in the area of neurovascular surgery.
