Laura is an independent Senior Research Fellow (Assistant Professor) with an interest in the recycling, reusing and repurposing of surplus human tissue donations to make regenerative therapies. She is particularly focused on eye regeneration and adult stem cell therapies.
Laura graduated from an undergraduate MEng degree in Biomaterial Science and Tissue Engineering from the University of Sheffield (2008), before the joining the inaugural year of the Doctoral Training Centre for Regenerative Medicine, where she completed her PhD in the School of Pharmacy, University of Nottingham (2013). She worked in Academic Ophthalmology, Division of Clinical Neuroscience as a research fellow from 2013 - 2017, investigating regenerative medicine uses for stem cells derived from the cornea and novel preservation methods for human donor corneas. In 2014, she was awarded the Early Stage Investigator Award by the Tissue and Cell Engineering Society (TCES).
Laura was promoted to Senior Research Fellow and was awarded an Anne McLaren Fellowship by the University of Nottingham (2017). In May 2020, Laura was awarded tenure with the School of Medicine as a Senior Research Fellow.

Laura's research focuses on recycling, reusing and repurposing of surplus human tissue donations to make ocular regenerative therapies. She is particularly focused on eye regeneration and adult stem cell therapies.
Broadly, she works in five main areas:
Human donor tissue preservation:
- Low-temperature vacuum evaporation for biological tissue
- Dry-preserved human and porcine corneal tissue for transplantation
- Preservation of amniotic membrane for transplantation
Cell biology of the anterior eye (predominantly cornea):
- Corneal stromal keratocyte to fibroblast transition
- Biological and mechanistic understanding of corneal mesenchymal stem cells
- Limbal stem cell biology and the stem cell niche
- Exosome signalling within the vitreous body
Stem cell and exosome therapies for the ocular surface:
- Topical corneal mesenchymal stem cell therapies for the injured eye
- GMP and optimised mesenchymal stem cell culture and quality control
- Limbal stem cell therapies and cell sheet technology
- Corneal mesenchymal stem cell derived exosomes as a topical therapy for the injured eye.
Biomaterials derived from surplus human donor tissue:
- Scleral/corneal ECM hydrogels for delivery of stem cells to the ocular surface
- Amniotic membrane powders and hydrogels
- Vitreous and lens-based biomaterials for ocular regeneration
In vitro models of the eye:
- Recellularised corneas as an alternative for animal models
- Standardised in vitro corneal cell inflammation models
