Dr. Alois Zauner is a board-certified Neurosurgeon and Neuroendovascular Surgeon specializing in complex cranial and neurovascular conditions. He completed his neurosurgery residency at Virginia Commonwealth University and advanced fellowship training in Neuroendovascular surgery at UCLA. Dr. Zauner dedicated three years to research at the National Institutes of Health and the Medical College of Virginia, where he focused on brain metabolism and brain oxygenation in patients after severe traumatic brain injury and after brain hemorrhage. This strong foundation provided him with a comprehensive, evidence-based approach to treating complex neurological disorders.

Over the course of his career, Dr. Zauner has performed more than 3,500 cerebral aneurysm procedures and over 15,000 open cranial, spinal, and endovascular procedures. His clinical expertise includes traumatic brain injury management, neurovascular surgery, brain tumor surgery, and advanced diagnostic and interventional neurovascular care. He is committed to utilizing both microsurgical and minimally invasive catheter-based techniques to deliver the safest and most effective treatment options for his patients.

Dr. Zauner is the founder of the Saving the Brain Conference on the Central Coast of California, an educational initiative dedicated to advancing best practices in neuroscience and neurovascular care. In 2021, he established the Enzian Neurovascular Research and Training Center in San Diego, a facility devoted to physician education, hands-on simulation, and innovation in catheter-based neurovascular technologies. Outside of medicine, Dr. Zauner is an avid skier and enjoys spending time with his wife and children.

Nathan Santos is a neurovascular researcher and biomedical developer focused on advancing the treatment of cerebrovascular disease through translational research, engineering, and physician collaboration. He holds a Bachelor’s degree in Biology and and a Master’s degree in Neurobiology. During his graduate training, Nathan completed a thesis in neuroimmunology, examining how physiological stress influences immune signaling in the brain and its potential implications for neurological disease.

Nathan’s work spans research, product development, and collaboration with physicians and industry partners in the neurovascular space. His efforts focus on translating clinical challenges into practical research tools and technical solutions that support the study of complex vascular anatomy and procedural techniques.

His research interests include intracranial aneurysm treatment, vascular biomechanics, and the development of reproducible anatomical models that support physician training and device evaluation. Through close collaboration with physicians and industry partners, Nathan works to develop technologies and research platforms that improve procedural understanding and ultimately advance patient care in neurovascular medicine.
