About

Dr. Corey R. Fehnel is a leading neurointensivist whose research bridges critical care neurology and cutting-edge technology. His primary focus lies in improving outcomes for patients with devastating neurological conditions, particularly subarachnoid hemorrhage (SAH) and stroke. Dr. Fehnel’s most notable contribution is pioneering the use of robotic assistance and artificial intelligence to perform transcranial Doppler (TCD) ultrasound—a vital but operator-dependent tool for detecting cerebral vasospasm after SAH. His landmark 2020 study, cited 22 times, demonstrated the clinical feasibility and strong concordance of a robotically assisted TCD system, offering a transformative solution to the critical shortage of skilled ultrasound operators. This work has the potential to expand access to life-saving monitoring in both academic and community hospitals. Beyond this innovation, Dr. Fehnel is recognized for his expertise in neurocritical care, medical education, and the development of protocols that enhance patient safety and recovery. His research continues to shape the future of acute neurological care by integrating automation and AI to overcome traditional clinical limitations.
