Overview
Research summary
My interest is in the use of magnetoencephalography (MEG) to explore perception and cognition, particularly within the domain of vision.
My current focus is on understanding the role of gamma oscillations in the visual system: How are they generated? What is their functional role? Can they provide information about disease states?
Teaching summary
I currently teach MEG lab and analysis practicals on module PST512 Introduction to Neuroimaging Methods and assist with projects using MEG on module PST510 Neuroimaging Research Project as part of the the MSc NeuroImaging: Methods and Applications course.
