Professor William Gray
Professor of Functional Neurosurgery, Neuroscience and Mental Health Innovation Institute
Overview
I am the director of Health and Care Research Wales funded BRAIN Unit and Professor of Neurosurgery. I undertake clinical research in epilepsy, the hippocampus, learning and memory.
My research involves imaging of epilepsy patients to understand seizure origins and cognitive dysfunction, intracranial EEG recordings, imaging white matter fibre streams, imaging grey matter structure, microstructure and fMRI.

We are using brain tissue to assess the effectiveness of cell transplantation for brain repair
Collaboration with Dr Y Zhu, Dr A Errington, Prof Meng Li & Prof W Gray.
Early Diagnoses of Brain Infection
Using Cerebrospinal Fluid (CSF) samples from patients with suspected infection we are examining the use of immune markers to accurately diagnose infection much earlier than with standard micriobiology cultures and so treat patients earlier.
