Research interests and approach:
1. Semantic cognition and its disorders: various interlinked projects explore the nature and neural underpinnings of semantic memory or conceptual knowledge. Our convergent, multimethod approach is founded in detailed, comparative investigations of semantic dementia, herpes simplex virus encephalitis (HSVE), aphasia after CVA and temporal lobe resection for epilepsy, and is complemented by parallel TMS, fMRI, structural and functional connectivity studies, and cortical-grid explorations.
2. Aphasia: multiple interlocking projects explore the cognitive and neural mechanisms that underpin acquired language impairments (aphasia). These include investigations of fluent and non-fluent varieties of progressive and non-progressive aphasia. Inspired by the patients, we also conduct parallel explorations in healthy participants utilising experimental psycholinguistics, TMS, computational modelling, fMRI, structural and functional connectivity analyses.
3. Recovery, rehabilitation and neuroplasticity: As well as concentrating on the nature of chronic and progressive cognitive and language deficits, the third theme is devoted to the study of the neural and cognitive principles that guide recovery and rehabilitation. This includes active rehabilitation programmes, longitudinal neuropsychological and neuroimaging assessment of recovery, computational models of neuroplasticity and parallel functional imaging studies of patients.
Our research makes parallel use of multiple methodologies in an attempt to secure convergent insights on the given research topic. These include: neuropsychology, computational models (models that can mimic neural organisation in their construction but also produce target behaviours), transcranial magnetic stimulation (TMS), structural and functional neuroimaging, and cortical grid-electrode studies.
Over the years, I have been lucky to work on these topics with many talented early career researchers and collaborators. Current fellows, postdocs and PhDs include:

I obtained my PhD from York University and then worked at the MRC Cognition and Brain Sciences Unit (Cambridge). I moved from there to the University of Bristol, Department of Experimental Psychology, as a Lecturer. I went to Manchester in 2001 as Professor of Cognitive Neuroscience within the School of Psychological Sciences, where I also became Associate Vice-President (Research) and Director of the Manchester Doctoral College. In 2018, I had the honour of being appointed as the Director of the MRC Cognition and Brain Sciences Unit.
I am an action editor for Neurobiology of Language, and Neuropsychological Rehabilitation. I am on the editorial boards for Cognitive Neuropsychology, Memory, International Journal of Language & Communication Disorders, Alzheimer's Research & Therapy, Psychologia, and Neurocase. I was the President of The British Neuropsychological Society (2010-12) and the Vice-Chair for the British Aphasiology Society (2000-2005). I was made a Fellow (hons) of the Royal College of Speech and Language Therapists in 2003, Fellow of the British Psychological Society in 2012 and Fellow of the Academy of Medical Sciences in 2019. I am also Honorary Research Professor of the University of Málaga in 2014 and a Senior Investigator Emeritus for the NIHR. I was awarded the BPS President's Award in 2015, the Barbara Newcombe (mid-career) Prize by the British Neuropsychological Society in 2016, the Mid-Career Award by the British Association for Cognitive Neuroscience in 2016, and the 17th Mid-Career Award by the Experimental Psychology Society in 2018. I am currently the chair of the EU Human Brain Project Stakeholder Board (the principal oversight committee).
