She is known for her work combining computational and systems neuroscience to understand how the brain encodes and processes self-motion (vestibular) information to ensure the maintenance of balance and stable perception.
[1][2] Her research also focuses on extending this knowledge to further advance the development of novel diagnostic tools, treatments, training, and rehabilitative strategies for patients.
[7] She is also the current president for the Society for the Neural Control of Movement[8] and served on the steering committee for NASA’s Decadal Survey on Biological and Physical Sciences Research in Space 2023-2032.
In 1994, she joined the Department of Physiology at McGill University as an assistant professor, with concurrent appointments in Biomedical Engineering, Neuroscience, and Otolaryngology.
[11] In 2016, Cullen moved to Johns Hopkins University, where she is currently a professor in biomedical engineering and maintains joint appointments in the Departments of Neuroscience and Otolaryngology–Head and Neck Surgery.
