Overview
How can we use new technological advances to develop novel solutions for health and social care? My research explores this question across different populations (older people, people with a learning disability, autistic people, people with dizziness) and across a range of technologies (bespoke to mainstream).
Some of my current projects include: understanding digital exclusion, smart devices to improve wellbeing, agency, and social connectivity for older people and people with a learning disability, virtual/Augmented reality and video games for people with chronic dizziness (in particular, persistent postural perceptual dizziness, PPPD, or 'visual vertigo'), and multi-sensory environments for Autistic people and people with a learning disability.
I use a mixed-methods approach that combines qualitative and quantitative measures, observational studies, neuroimaging, and psychophysics. I work closely with practitioners, social care organisations and people with lived experience to co-develop my research projects.

Research
Smart technology in social care settings
Learn about our research here!
Can smart home technologies improve wellbeing, independence, loneliness, and safety in social care settings? In collaboration with social care organisations, I'm investigating this question for older adults and people with a learning (intellectual) disability.
Smart technology is becoming increasingly ubiquitous in daily life, and social care could capitalise on these advances to develop new models of support.
Mainstream smart technologies allow people to control their home environment via voice commands, set reminders for medication and daily routines, add social value, and provide greater accessibility than traditional devices.
Persistent Postural Perceptual Dizziness (PPPD, or 'visual vertigo')
Find out more at the Cardiff University Dizzy Lab webpage!
We are collaborating with vestibular clinicians at University Hospital Wales seeking to understand more about the causes of PPPD and other dizziness conditions, and develop better tools to measure and rehabilitate them.
We have developed a new web-based rehabilitation game for visual vertigo called Balance-Land - you can learn more about it here!
Our research so far has shown that symptoms visual vertigo are remarkably common in the general population and that the condition is associated with avoidance and sensitivity across all senses (i.e. not just limited to vision and vestibular).
We have also developed a new questionnaire, the Cardiff Hypersensitivity Scale - Visual (CHYPS), which defines and measures the four factors of visual sensitivity.
If you are a clinician and would like to access our videos showing environments that are potential triggers for PPPD, please visit the Cardiff PPPD project webpage.
Sensory environments (multi-sensory environments, sensory rooms) for autistic people, people with a learning disability and people with other conditions
Sensory environments can have a big impact on our wellbeing - is the light too bright? Is there too much background noise? But sensory stimulation can also be relaxing and soothing when we are stressed and upset.
We are exploring individual differences in sensory experiences and the importance of sensory environments in a number of different populations and settings. These include, multi-sensory environments (sensory rooms) in educational settings for autistic children and young people, sensory environments in the home for people with a learning (intellectual) disability, and individual differences in the general population.
In collaboration with Catherine Jones, I'm using a purpose-build sensory room based at the Cardiff University Centre for Human Developmental Science to understand more about how and why to use sensory rooms. We have developed an evidenced-based guide for using sensory rooms in educational settings for autistic children, which can be accessed here
