Joseph P. Antonios, MD, PhD, is a neurovascular neurosurgery fellow at the University of Washington. He completed his neurosurgery residency at Yale and received his MD and PhD in Neuroscience through the UCLA-Caltech Medical Scientist Training Program. His early research focused on glioblastoma immunology and immunotherapeutic strategies, with work published in *PNAS*, *Neuro-Oncology*, *JCI Insight*, and other journals. During residency, his research interests shifted toward cerebrovascular disease, with a focus on the immune mechanisms underlying intracranial aneurysm formation, progression, and rupture. His recent work using endoluminal biopsy and single-cell immune profiling of intracranial aneurysms was published in *Neurology* and recognized with the CNS Resident Award. He has also received the Cerebrovascular Section Best Basic Scientific Paper Abstract Award and the New England Neurosurgical Society Matson Resident Basic Science Award. Clinically, he is pursuing advanced training in cerebrovascular surgery, with interests in aneurysms, vascular malformations, stroke, and translational neurovascular.
