Optimising paediatric traumatic brain injury (TBI) outcomes

Dr Phil Lewis's research interest is how
the brain regulates blood flow

Dr Philip Lewis completed his PhD during 2014, in which he studied the regulation of blood flow in the brain. Often after traumatic brain injury (TBI), this regulation mechanism is disrupted. As a result, during episodes of low blood pressure the brain cannot prevent a drop in flow. Conversely, during high blood pressure episodes the brain swells as the non-reactive blood vessels stretch. His thesis examined how this mechanism works, and the development of techniques for measuring its deterioration.
