Research interests
I investigate the neurobiological basis of language using a variety of neuroimaging techniques. My research interests include, but are not limited to, the study of combinatorial language processing, speech production, the systems engaged by semantic and episodic memory, and the interplay between language and the default mode network and executive systems.
Much of my research has focused on understanding the functional contribution of parietal cortex to language and memory. I have developed a unifying model in which the lateral parietal cortex operates with a core underlying neurocomputational function; the multi-sensory buffering of spatio-temporally extended representations. Saying this, although a variety of cognitive activities might draw on shared underlying machinery, variations in task preference across lateral parietal cortex, arise from graded changes in the underlying structural connectivity of the region to different input/output information sources.
Biographical information
I completed my PhD in the Department of Psychology at the University of York in 2013 before taking up a position as a Research Associate at the University of Manchester. I moved to the Cognition and Brain Sciences Unit in 2018 where I continue my research.
