About the Lab

Pain is one of the most common reasons patients seek help from medical professionals. In contrast to acute pain which has a protective function, chronic pain is a state with maintained abnormalities in both the central nervous system and periphery. Dr. Chung is interested in the mechanisms of chronic pain. The studies in her laboratory include the changes in behavior, morphology, and physiological properties in primary afferent neurons and spinal dorsal horn neurons following peripheral nerve injury or tissue inflammation. The current studies focus on mitochondrial production of highly reactive oxygen species (free radicals) and their role in sensitization of spinal dorsal horn neurons and pain.
