Neurotherapeutics Research

Our research focuses on the rehabilitation of acquired language and cognitive impairments, in individuals who have had a stroke and those with dementia. We specialise in developing novel digital interventions (i.e. apps and web-based therapies) for hemianopic alexia, aphasia and other neurological conditions.

We are passionate about involving end users in the co-design of our therapy apps and at all stages of our research.

We are also interested in the potential application of non-invasive brain stimulation (e.g. tDCS) in enhancing therapy effects, and improving language recovery.

We use a range of neuroimaging techniques (including MRI, fMRI and MEG) to further our understanding of the language network, identify how the brain changes in response to rehabilitation (neuroplasticity) and to explain and predict individual differences in recovery.

Catherine is a Post Doc and Clinical Psychologist who is working on developing three Digital Interventions in Neuro-Rehabilitation (DINR). The first, iTALKbetter, is an interactive word retrieval therapy for with people with aphasia; the second is to help people with dementia remember the names of familiar people, while the third is for stroke patients with visuo-spatial neglect.

Language is our defining cognitive skill. I study the neurobiology of language in health and disease, with a particular focus on language impairments consequent to abrupt brain damage (e.g. in stroke). By studying how damage causes deficits, I aim to infer the organisation of language in the undamaged brain. I also try to understand how patients recover from these impairments, and in this sense my research also addresses neuroplasticity. My most recent work aims to understand why some patients respond so much more quickly and fully to therapeutic interventions for these impairments than others. By showing that this inter-patient variability is systematic, and even predictable to some extent, I hope to contribute to a more positive and personalised medicine for these patients. 

PhD Students  

Haya Akkad

Haya Akkad

Haya is a PhD student with a background in clinical and cognitive neuroscience. She is funded by an independent BRUK fellowship to improve recovery in patients left with speech production difficulties after a stroke. To do this, she uses methods of non-invasive brain stimulation, specifically transcranial alternating current stimulation (tACS), alongside functional brain imaging techniques such as MEG and fMRI to characterise the coordinated interactions between brain regions that support successful speech prduction. She uses this to inform the development of a non-invasive brain stimulation intervention that can be used alongside behavioural treatment to strengthen brain network functionality and improve speech rehabilitation in patients with post-stroke Aphasia.

Sharifa Al-Ragam

Sharifa Al-Ragam

Sharifa completed a PhD whilst at the Neurotherapeutics lab. Her researched focused on the development and validation of a therapy app for Arabic readers with Hemianopic Alexia. She used behavioural testing and eye-movement tracking to achieve this. The app retains eye movements that are important for reading using scrolling text. After her time at the Neurotherapeutics lab, Sharifa returned to Kuwait to a position as Assistant Professor at the Public Authority for Applied Education and Training.

Davide Nardo

Davide Nardo

Davide is a postdoctoral research associate with a background in cognitive and clinical neuroscience. During his time at the lab, he used behavioural and functional neuroimaging techniques to investigate the effects of neurostimulation (tDCS) and phonemic-cueing-based anomia training on spoken language recovery in chronic aphasic patients. After leaving the Neurotherapeutics lab, Davide moved to the Cambridge Brain Sciences Unit to work with Dr. Michael Anderson.

Katerina Pappa

Katerina worked as a research assistant with an interest in the neurorehabilitation of aphasic patients with speech production difficulties. Whilst working at the NT lab, she implemented neurostimulation techniques (tDCS) combined with functional neuroimaging techniques and behavioural training. Katerina left the Neurotherapeutics lab to take up a PhD position at the University of Glasgow under the supervision of Professor Jonathan Evans.

Sonia Brownsett

sonia Brownsett

Sonia Brownsett was a post-doc and Speech and Language therapist at the Neurotherapeutics lab, she worked on the ‘Listen-in’ project. This project aimed to combine therapy for auditory comprehension deficits with gamification technologies in order to maximally engage patients with their aphasia therapy. During her PhD she developed a computer-based therapy targeting auditory discrimination deficits and used fMRI to investigate how ‘non-language’ areas of the brain are important in the rehabilitation of aphasia. After working at the Neurotherapeutics lab, Sonia moved to the Queensland University of Technology.

Zoe Woodhead


During her time at the Neurotherapeutics lab, Zoe worked as a Post-doctoral researcher on the 'iReadMore' project. This project investigated whether a therapy app for acquired reading disorders after stroke, called ‘iReadMore’, improved single word reading. She continues to collaborate with the Neurotherapeutics group on the online release of the iReadMore app. In 2016, Zoe moved to the University of Oxford, to take up a Postdoctoral Research Associate position working for Dorothy Bishop in the OSCCI lab. Her current research uses functional magnetic resonance imaging (fMRI) and functional transcranial doppler sonography (fTCD) to investigate the profile of lateralisation across various language tasks.
