His research interests also focus on the role of circulating extracellular vesicles in the pathogenesis of CNS diseases and the contribution of cytokine production to neuropsychiatric disorders.
His work has led to the identification of novel biomarkers for diagnosing disease and predicting progression, leveraging a combination of in vivo biology, molecular biology, immunohistochemistry, MRI and PET imaging, and metabolomics. After a stint at the University of Southampton, where he was a Lecturer in Neurobiology, he returned to Oxford in 2004, where he continues to explore the neurobiology of inflammation with research collaborations throughout the world. In 2015, he was awarded a personal Chair in Experimental Neuropathology, and he was made a Fellow of the British Pharmacological Society in 2020.
