    Current Research and Scholarly InterestsWe are committed to promoting an understanding of cerebrospinal fluid (CSF) leaks, and ensuring that all patients who are suffering from cerebrospinal fluid leaks receive appropriate diagnosis and treatment of this devastating, chronic, and fixable condition. We believe this can be best accomplished in a multidisciplinary setting involving expertise in radiology, neurology, and interventional pain medicine.

    Assistant Professor of Anesthesiology, Perioperative and Pain Medicine (Adult Pain)

    Current Research and Scholarly InterestsMy research focuses on understanding the plasticity in pain-modulating circuits in pathological pain states. I started with defining a basic functional framework that links the pain-transmission system to the pain-modulation system, through which I explored the central mechanism of sensitization in chronic pain after a peripheral injury. Based on this fundamental observation, my work now focuses on investigating the pathophysiology and the role of endogenous opioids in chronic pain related to brain injury and other forms of trauma, a topic especially relevant to chronic post-traumatic pain sufferers. Clinically, I am exploring the use of advance image-guidance in pain interventions for treating complex headache and craniofacial pain. Ultimately, I hope to translate these fundamental knowledge and technologies to patient care and provide potential new therapeutic targets to help those with pain after head injury and polytrauma.
