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. -

Dr. Stefanick’s research focuses on chronic disease prevention (particularly, heart disease, breast cancer, osteoporosis, and dementia) in both women and men. She is currently the Principal Investigator the Women’s Health Initiative (WHI) Extension Study, having been the PI of the Stanford Clinical Center of the landmark WHI Clinical Trials and Observational Study since 1994 and Chair of the WHI Steering and Executive Committees from 1998-2011, as well as PI of the WHI Strong and Healthy (WHISH) Trial which is testing the hypothesis that a DHHS-based physical activity intervention, being delivered to a multi-ethnic cohort of about 24,000 WHI participants across the U.S., aged 68-99 when the trial started in 2015, will reduce major cardiovascular events over 8 years, compared to an equal number of “usual activity” controls. Dr. Stefanick is also PI of the Osteoporotic Study of Men (MrOS) which is continuing to conduct clinical assessments of bone and body composition in survivors of an original cohort of nearly 6000 men aged 65 and over in 2001. As founding Director of the Stanford Women’s Health and Sex Differences in Medicine (WHSDM, “wisdom”) Center, she plays a major role in promoting research and teaching on Sex and Gender in Human Physiology and Disease, Women’s Health and Queer Health and Medicine. Dr. Stefanick also plays major leadership roles at the Stanford School of Medicine, including as co-leader of the Population Sciences Program of the Stanford Cancer Institute, Stanford’s NCI-funded comprehensive cancer center.
Dr. Stefanick obtained her B.A. in biology from the University of Pennsylvania, Philadelphia, PA (1974), then pursued her interest in hormone and sex difference research at the Oregon Regional Primate Research Center, after which she obtained her PhD in Physiology at Stanford University, focusing on reproductive physiology and neuroendocrinology, with exercise physiology as a secondary focus. Her commitment to human research led to a post-doctoral fellowship in Cardiovascular Disease Prevention at the Stanford Prevention Research Center, which has been her academic home for nearly 40 years. -
