I am a behavioural neurologist. I teach MSc courses in neuroimaging and neuropsychology to students from the School of Psychology at Bangor University. I am interested in characterizing the functional and anatomical organization of visual memory in healthy individuals and patients with focal brain injuries and neurodevelopmental disorders using behavioral and imaging methods. As part of a team I have been developing an unbiased assessment digital battery designed to assess cognitive performance in populations with low literacy and numeracy skills. Finally, I am coollaborating with NHS clincians to advance clincial practice and research activities in neurorehabilitation across North Wales.
