Ian Galea is Associate Professor in Experimental Neurology at the University of Southampton and Honorary Neurology Consultant at the Wessex Neurosciences Centre. He has a special interest in the interaction between blood and brain, especially relating to the source, consequence and fate of extracellular haemoglobin in the brain, and the blood-brain barrier. Seminal contributions to the field include the first description of the haemoglobin scavenging system and haemoglobin neurotoxicity in the human brain, the development of a subarachnoid haemorrhage-specific outcome tool, and the development and application of tools to study blood-brain barrier function in vivo. His work spans clinical and preclinical domains, including clinical outcome prediction, clinical assessment, neuro-imaging, cell culture, immunochemistry, molecular techniques and preclinical modelling. A main focus is to turn basic science discoveries into clinically applicable tools and therapies. He will be speaking about pathological processes influencing outcome after subarachnoid haemorrhage.
