Tamsin has over 15 years of experience in Optometry and is a qualified Dispensing Optician and Optometrist.

For her PhD Tamsin looked at into the role of a lack of oxygen in the development of Age-related Macular Degeneration, and if a lack of oxygen was responsible for the changes seen in dark adapted visual function in this condition.

Tamsin has experience of teaching and lecturing at an undergraduate and postgraduate level and in 2015 joined City University as a lecturer in the Division of Optometry and Visual Science, where she carries out both research and teaching roles.

Currently, Tamsin is the Primary Investigator on a project investigating home monitoring in glaucoma.


Postgraduate Diploma in Academic Practice, BSc Optometry and Vision Science, Fellowship Dispensing Diploma and PhD in Optometry and Vision Science.

Research overview

Tamsin's primary research interest is Age-related macular Degeneration (AMD) and in particular in the aetiology and pathogenesis of the condition. Tamsin is also interested in investigating functional biomarkers for the early stages of the condition and the effect AMD has on retinal structure and visual function.
