Assistant Professor of Neurosurgery

Research Interests: Peripheral neural mechanisms of Chronic pain and itch


Dr. Qu is an assistant professor in the Department of Neurosurgery. His research interest mainly focuses on the peripheral neural mechanisms of chronic pain and itch in the context of nerve injury and inflammation using a combination of approaches, including immunohistochemistry, whole-cell recordings, calcium imaging, molecular biology, in vivo calcium imaging and electrophysiological recordings on the intact DRG, and pain related behavioral assessments.

Dr. Qu earned his Ph.D. degree from University of Western Ontario, Canada in 2009. After completion of his degree, He joined Dr. Robert LaMotte’s laboratory as a postdoc associate in the Department of Anesthesiology at Yale University. Dr. Qu joined the Johns Hopkins faculty in 2014. more
