Academic Pursuits

Dr. Zazulia is the Associate Dean for Continuing Medical Education (CME) at Washington University and is the director of Pre-clinical Neurological Education for Washington University medical students and the Department of Neurology.

In her CME role, she leads the University office dedicated to promoting life-long learning and professional development across the medical continuum and assisting health care professionals in maintaining professional competencies and performance to improve patient care.

Dr. Zazulia has been involved in pre-clinical neurological education since 2001, teaching the neurological exam to first and second year medical students, leading a selective entitled “Clinical Correlations in the Neurosciences” for first year students, and directing “Diseases of the Nervous System,” a coordinated course in neuropathophysiology, neuropathology, and neuropharmacology for second year students. She is the faculty preceptor for the Student Interest Group in Neurology (SIGN) and Camp Neuro, a non-profit summer day camp for high school students interested in exploring a career in medical neuroscience and established the College Student Interest Group in Neurology (Synapse, formerly Co-SIGN) at the undergraduate campus of Washington University. She directs an annual 16-part series entitled “Evidence-Based Management of Cerebrovascular Disease” and regularly teaches residents, clerkship medical students, and physical and occupational therapy students. She has had a prominent role in mentoring trainees and junior faculty aspiring to a research career in medicine, recently serving as the Assistant Program Director of the Clinical Research Training Center, program mentor in the Masters in Science in Clinical Investigation program, and co-director of the Neuroscience T32 Institutional Training Grant at Washington University.

On the national level, Dr. Zazulia has positions on education committees through the American Board of Psychiatry and Neurology, the National Board of Medical Examiners, the American Stroke Association, and the American Academy of Neurology. She is an elected fellow of the American Neurological Association and the American Heart Association. She is a member of the Alpha Omega Alpha Medical Honor Society, American Academy of Neurology, American Heart Association Scientific Council on Stroke, Alliance for Continuing Education in the Health Professions, and Society for Academic Continuing Medical Education.

Dr. Zazulia’s research interests are in medical education and engaging residents in process improvement. Her former research program involved use of positron emission tomography (PET) and magnetic resonance imaging (MRI) to study cerebrovascular regulation following acute intracerebral hemorrhage, ischemic stroke, subarachnoid hemorrhage, and traumatic brain injury and to study cerebrovascular effects of Alzheimer’s disease and of severe congestive heart failure/cardiac transplantation.
