Timo Krings, PhD, MD, FRCPC
Dr. Krings studied medicine in Aachen, Germany and at Harvard Medical School in Boston. After residency training in Neuroradiology in Aachen with Prof. Armin Thron, he completed a neurointerventional fellowship with Professor Pierre Lasjaunias in Paris, France and subsequently joined the Neuroradiology division of the University of Toronto as a diagnostic and interventional Neuroradiologist in 2008. He is currently cross appointed to Radiology and Neurosurgery at UHN and as an interventional Neuroradiologist at the Hospital for Sick Children. He is a Full Professor of Radiology and Surgery, and staff Diagnostic and Interventional Neuroradiologist at the University Health Network, Mount Sinai and Women’s College Hospitals. He holds the David Braley and Nancy Gordon Chair in Interventional Neuroradiology at the University of Toronto and is the Program Director of Interventional Neuroradiology at the Toronto Western Hospital.
Focusing his research efforts on Imaging and Treatment of Neurovascular Diseases, Dr. Krings has published more than 470 peer reviewed articles, and approximately 30 book chapters and four books on spinal, pediatric and interventional neuroradiology, and neurovascular anatomy.
His current research focusses on the prediction of brain bleeding from brain vascular malformations using a multidiscplinary approach, development of novel methods to treat these life changing events and estimating the relative effectiveness of treatments to determine the impact on Health Care. To this end he is working with a team of Neuro-imagers, Neurointerventionalists, Computational Scientists, Genetist Biologists and Epidemiologists within the Division of Neuroradiology.
Dr. Krings’s leadership in the field of Neuroradiology is bolstered by his distinguished grants and awards, including the Scientific Award of the European Society of Neuroradiology, the Lucien Appel Prize, and the Founders Award in Interventional Neuroradiology of the ESNR. For the development of the Neuroradiology Program in Toronto he won the Anderson Award of the Wightman-Berris Academy and was granted the Edward Lansdown Award for outstanding teaching in the Residency Program of the University of Toronto. In 2021 he received the Gold Medal of the British Society of Neuroradiology associated with the Kendall Lectureship.
