Bonaventure Ip focuses on various aspects of cerebrovascular diseases, including stroke epidemiology, intracranial atherosclerosis, advanced neuroimaging, stroke-related big data analytics, treatment and outcome, and cerebral small vessel disease. He seeks to gain deeper insights into the pathogenesis, prognosis, and therapeutic avenues for neurological diseases.

Bonaventure Ip is a vascular and interventional neurologist currently serving as a Clinical Assistant Professor at the Chinese University of Hong Kong.

Actively involved in various professional organizations and committees, Bonaventure serves as a co-opt member of the Hong Kong Neurological Society, a young council member of the Chinese Association of Integrative Medicine and Interventional Treatment, and a regional committee member of the Society of Vascular Interventional Neurology (SVIN). Furthermore, he works as an assistant editor for the International Journal of Stroke and contributes as a reviewer for esteemed journals such as The Lancet, Journal of Neurology, Neurosurgery and Psychiatry, Alzheimer’s & Dementia, and International Journal of Stroke.

Driven by his passion for improving the lives of stroke patients and their families, Bonaventure focuses on both clinical care and research. His research interests encompass various areas, including anticoagulation, stroke-related big data analytics, advanced neuroimaging, and endovascular thrombectomy. Through collaborative efforts with experts from different disciplines and across the globe, Bonaventure has obtained multiple external competitive grants and published multiple peer-reviewed articles as a Principal Investigator. His research has been published in first-tier peer-reviewed journals such as Science Robotics, Nature Communications, JAMA Network Open, Neurology, Stroke, and the International Journal of Stroke.

Bonaventure’s contributions to the field of medicine have been recognized through several awards. He was honored with the Hong Kong College of Physicians Distinguished Research Paper Award in 2023 and received the Best Free Paper Award and Best Dissertation Award at the Hong Kong Neurological Society Annual Scientific Meeting in 2021 and 2019, and Hospital Authority Outstanding Team Award (Stroke Team) in 2019. Additionally, he is deeply committed to medical education and has been awarded as an exemplary and outstanding teacher by the Faculty multiple times.
