Dr. Michelle C. Johansen is an assistant professor of neurology and attending physician in the Cerebrovascular Division at the Johns Hopkins Hospital. A board certified general and cerebrovascular neurologist, Dr. Johansen divides her time between research and clinical duties. She is the recipient of the American Heart Association Mentored Clinical and Population Grant as well as the Cardiovascular Epidemiology T32 Research Grant, which enables her to continue studying the relationship between stroke and heart health. She is also the recipient of the Johns Hopkins Clinical Research Scholar KL-2 Mentored Career Development Award and serves as an expert reviewer for medical journals such as Stroke and Neurology.
Dr. Johansen completed her clinical fellowship at Johns Hopkins in cerebrovascular neurology in 2016. During this time, her research continued to develop with her work accepted for presentation at venues such as the International Stroke Conference and the American Academy of Neurology.
She completed her neurology residency at the University of Virginia in 2015. During that time, she served as the Research and Quality Chief Resident and was awarded the Colligan Safety and Quality Improvement Grant. She designed and performed a study targeting stroke in the setting of cardiac catheterization and presented this as a junior investigator at the International Stroke Conference. She also participated on the study team for the National Stroke Hyperglycemia Insulin Network Effort (SHINE) trial as well as the Biorepository to Establish the Aetiology of Sinovenous Thrombosis (BEAST) study.
Dr. Johansen attended the Medical College of Virginia, graduating in 2011. She was one of only 25 students selected to spend two years on the Fairfax INOVA campus in Northern VA. During that time she served as the curriculum chair and was awarded the Department of Neuroscience Award for Excellence. She was the student leader for the Medical Spanish Language Club and organized the school’s medical Spanish elective. Dr. Johansen was recognized for her scholarship and contributions by being named to the Alpha Omega Alpha Medical Honor Society. She served on two medical service trips to El Salvador.
Her undergraduate work took place at the University of Virginia where she graduated with a bachelor of sciences in chemistry with distinction. There she was the outreach chair for the Women in Medicine Initiative Organization; served as a Spanish translator at UVA hospital and was named to the Gold Key Honor Society and NCAA Athlete Honor Roll. She also volunteered as an aquatic therapist at the Kluge Children Rehabilitation Center in Charlottesville and tutored elementary students struggling with math and science.

Research & Publications
Dr. Johansen’s research interest lie in the heart brain connection, specifically with regards to earlier diagnosis and ultimately prevention of cardioembolic stroke. Current research efforts focus on characterizing and then utilizing cardiac anatomy in ischemic stroke patients to improve stroke subtype diagnosis, codify risk of stroke recurrence and describe patient functional outcomes.
