Kristen K. Steenerson, MD
Clinical Associate Professor, Otolaryngology (Head and Neck Surgery)
Clinical Assistant Professor, Adult NeurologyBio=Dr. Kristen K. Steenerson is a Clinical Associate Professor at Stanford University School of Medicine, specializing in vestibular neurology and neuro-otology. She directs clinical care within the Vestibular Neurology Clinic at the Stanford Ear Institute, where she focuses on the diagnosis and management of complex dizziness and balance disorders, including vestibular migraine, benign paroxysmal positional vertigo, Ménière disease, bilateral vestibulopathy, and persistent postural-perceptual dizziness.
Her academic program integrates translational research with clinician education to improve the diagnosis and treatment of vestibular disorders. Her research focuses on the development and validation of objective, technology-enabled tools to measure vestibular function in real-world settings. She leads initiatives evaluating wearable electro-oculography platforms for ambulatory nystagmus detection, as well as sensor-based systems using inertial measurement units to assess mobility, fall risk, and functional engagement. Her work leverages multidisciplinary collaboration across neurology, otolaryngology, audiology, engineering, and data science, with the goal of establishing scalable digital biomarkers and vestibular-specific clinical trial endpoints.
In parallel, Dr. Steenerson is deeply engaged in national and international clinician education. She serves as course director and faculty for multiple continuing medical education programs in vestibular neurology and neuro-otology, with a focus on bedside examination skills, acute dizziness evaluation, and diagnostic reasoning. She has developed interdisciplinary curricula and clinical training pathways designed to expand vestibular expertise among neurologists, otolaryngologists, advanced practice providers, and trainees.
Her scholarly work also includes clinical outcomes research and care delivery innovation, particularly in vestibular migraine and episodic vertigo disorders. She has led initiatives to standardize triage, referral pathways, and multidisciplinary care models for patients with dizziness, translating evidence into practical frameworks that improve access, diagnostic accuracy, and patient outcomes.
Through the integration of clinical innovation, translational research, and clinician education, Dr. Steenerson’s work aims to modernize vestibular care and expand the reach of specialized expertise beyond tertiary referral centers. -

Ryan Taylor, MD
Clinical Assistant Professor, Adult Neurology
BioDr. Taylor is a fellowship-trained neurologist and assistant professor in the Department of Neurology and Neurological Sciences, Memory Disorders Division. He provides patient care at the Stanford Center for Memory Disorders.
His areas of expertise include diagnosing and treating illnesses that impair thinking, memory, behavior, and speech. Dr. Taylor’s clinical focus includes Alzheimer’s disease, Lewy body disease, frontotemporal dementia, primary progressive aphasia, posterior cortical atrophy, Creutzfeldt-Jakob disease, autoimmune encephalitis and other rapidly progressive dementias. He works with patients and families to provide diagnostic clarity and individualized treatment plans.
Dr. Taylor’s academic and research interests combine clinical and scientific understandings of dementia with a philosophical inquiry into the structure of conscious experience. His original clinical research includes diverse topics, such as advances in diagnosing Creutzfeldt-Jakob disease and the clinical characterization of adult-onset hereditary dementias. Dr. Taylor has published work instrumental in identifying the potential role of fentanyl in a syndrome of sudden onset amnesia that emerged during the opioid crisis.
He has presented research at the American Academy of Neurology and published in peer-reviewed journals, including the Canadian Journal of Neurological Sciences and Methods in Molecular Biology. He has also published a chapter on the diagnosis and treatment of frontotemporal dementia and was a reviewer for Neurocase.
Dr. Taylor is a fellow of the Royal College of Physicians of Canada. He has taught residents and medical students clinical skills, neuroanatomy, neuro-imaging, and other subjects. He also has delivered Grand Rounds presentations on dementia, epilepsy, and pediatric neurology. -
