Neurotrauma and Stroke

Research Overview

Stoke is a common and serious condition, with few therapies. Whilst previous research has been directed towards preventing the progression of injury during the acute phase, new evidence suggests that targeting brain repair and remodelling may be a better approach for the majority of stroke survivors who live with an ongoing disability.

Our focus is to identify new targets in the brain for promoting brain repair as well as develop new treatment strategies that facilitate functional recovery.  In particular current projects centre on the role of the neurovascular unit in brain rescue and include drug therapies to target astrogliosis and epidural electrical stimulation to awaken and reconnect cells for restored nerve transmission.

Working closely with leading clinicians at St Vincent’s Hospital who specialise in brain disorders our team is committed to research that is focused on translation of positive outcomes in animal models to clinical success.
