    Collapse Overview
    Alexander A. Khalessi, MD MBA MS, specializes in cranial and endovascular neurosurgery.

    Dr. Khalessi graduated from Stanford University with departmental honors in public policy and a Master of Science degree in health services research. After earning his medical degree at the Johns Hopkins School of Medicine, Dr. Khalessi completed his neurosurgical residency at the University of Southern California and internationally recognized endovascular neurosurgery fellowship with Dr. Nick Hopkins at SUNY Buffalo. He came to UC San Diego after expanding the endovascular neurosurgery service as a Clinical Instructor at LAC + USC. He earned his Master of Business Administration from the Sloan School of Management at Massachusetts Institute of Technology (MIT).

    Dr. Khalessi holds several national leadership positions in both graduate medical education and the treatment of cerebrovascular disease. He serves as a member of the Residency Review Committee for Neurosurgery and Editorial Board for the Journal of Graduate Medical Education. Dr. Khalessi was further named to the ACGME Working Group for Neurosurgical Milestones that will define the national standards of neurosurgical training.

    Within his subspecialty, Dr. Khalessi is a member AANS/CNS Joint Clinical Guidelines Committee that defines clinical practice standards, Executive Committee of the Joint AANS/CNS Cerebrovascular Section, and is principal editor of a free standing Ischemic Stroke Supplement for World Neurosurgery, the official Journal of the World Federation of Neurosurgical Societies.

    Dr. Khalessi’s research interests include open surgical and endovascular therapies for intracranial aneurysms, large-vessel ischemic stroke, and intensive care management and prognosis in head injury.
