I am Group Lead for the Exosome and Retinal Research Group. In my laboratory we develop new therapies to better treat traumatic and degenerative eye diseases, including glaucoma. Our research focuses on the use of stem cells and their secreted compounds to prevent cellular loss in the retina and preserve vision. Of particular interest to me are exosomes, small extracellular vesicles that are secreted from cells and appear to possess remarkable therapeutic potential. Our work also seeks to better model eye disease, either with more robust animal models or through the utilization of human retinal culture systems.

We collaborate closely with the National Eye Institute, NIH, USA. I am happy to communicate with individuals seeking to learn more about my work along with any potential collaborators or prospective students.

OP1207 Physiology of Vision

OP0201 Human Development

I did my undergraduate degree in Biomedical Neuroscience at the University of Birmingham (2008-2011) followed by a Masters in Biomedical Research (2011-2012) and a PhD in Traumatic and Degenerative Eye Disease (2012-2015), which was via the Alternative Format (PhD-by-publication).

Following my PhD I moved overseas and took up a Visiting Fellowship as well as later, a Marie Curie EU Fellowship in the US at the National Eye Institute, National Institutes of Health (2015-2019). I then returned to the University of Birmingham for a short duration before taking up a lectureship at Cardiff University, School of Optometry.
