Dr Mohamed Seghier - Senior Research Fellow

Mohamed is head of image processing for the PLORAS team.  He has pioneered new ways to identify and describe lesion sites in the brain images of stroke survivors.  He is also pioneering new ways to understand how the brain re-connects itself after brain damage.

In addition to a background in engineering and image processing,  Mohamed is also an expert in how language processing occurs in the human brain; and how the contribution of the left and right hemispheres varies in different individuals.

Dr Tom Hope - Research Fellow

Tom is responsible for building and refining the PLORAS prognosis prediction system.  This involves pulling results and insights gained both from his own research and from that of the other group members into a single, coherent, practical framework.  He then validates their impact on the predictions that we can make for individual patients.

Tom has a PhD in Computational Cognitive Neuroscience (number processing in the brain), and a background in Artificial Intelligence, including medical applications.

Professor David Green - Professorial Research Fellow/Emeritus Professor

David is a world expert in the neural and cognitive processes that support multilingualism.  He has a special interest in how the effects of stroke on language recovery might vary in monolingual and multilingual speakers.

Previous members 

  • Louise Lim

Louise played a pioneering role in the PLORAS project, masterminding the patient recruitment procedures, testing and PR for the PLORAS team from 2009 to 2015. She started part-time with a few patient leads and built up a powerful system that advertised the PLORAS project throughout the UK; encouraging hundreds of stroke survivors to volunteer their time and brain images to the PLORAS study. Her overwhelming contribution to the project was underpinned by her former PR expertise, speech and language therapy training and experience, team management skills and fun and creative personality.

She created an environment where patients’ needs were at the core of the research, every team member was valued and every problem was successfully and sensitively managed. She passionately conveyed the importance of communicating information about aphasia to health professionals and the wider public; using every media source and event possible ranging from TV, radio, YouTube, Facebook, Twitter, newspapers, magazines, scientific journals and talks and speeches at stroke clubs and conferences all over the UK.
