Having obtained my PhD from the University of Sheffield I continued to develop and expand my research interests into the genetics and behaviour of uveal melanoma. Sheffield is one of three national centres for the treatment of uveal melanoma, and I have worked closely with Professor Ian Rennie to establish an active research group investigating how the genetic basis of uveal melanoma underpins its behaviour. In recent years I have expanded my research interests to include sarcomas, another rare tumour, and whilst continuing to work with Professor Rennie, I am now working in collaboration with Professor Malcolm Reed to develop and expand research into the genetic basis of sarcomas. As a consequence I have now established the Rare Tumour Research Group (RTRG) to allow cross fertilization of ideas and the development of strong working associations supporting all researchers working with me.
My research interests are the genetic and biological behaviour of uveal melanoma. Initial studies have lead to a good understanding of some of the principle genetic changes in uveal melanoma and how they correlate and can be used to predict prognosis. My research continues to investigate the genetic basis of uveal melanomas but has broadened in recent years to consider how the interaction with the environment affects the way these melanomas develop. In addition I have become actively involved in investigating the genetic characterization of sarcoma and developing a molecular pathological classification suitable for all subtypes.
I am the course lead for Pathology on the undergraduate BMedSci Orthoptics course. The course spans two academic years and covers the basis of Ophthalmic disease, its presentation and consequences. In addition I offer a supportive role annually to up to 5 students in the second year of the MB.ChB. degree course, who select to undertake their research attachment with the research group. Following on from these attachments a number of students have subsequently chosen to continue their research under my supervision by undertaking a BMedSci. I am also a regular supervisor of both MSc students from University of Sheffield and Hallam University.
- Regular reviewer for both Cancer and Ophthalmology journals.
- Reviewer for national and international grants.
- Understanding the aggressive behaviour of uveal melanoma, and the potential role that stem cells may have.
- Determining the key genetic events in the development of uveal melanoma
- Investigating how the environment may influence the behaviour and development of uveal melanoma
- The molecular pathological classification of sarcomas.
- Investigating how genetic defects influence sarcoma behaviour.
Within each project area are a number of smaller focussed research projects suitable for development as student projects, although funding is not currently available for these projects. Interested students are welcome to contact me to discuss the possibilities of undertaking research with the RTRG.
