Interests

I investigate human retinal function in health and disease, using electrophysiology and complementary approaches including retinal imaging, genetic investigation and machine learning.

Key current areas of investigation:

-Retinal structure and function in inherited retinal diseases and selected acquired diseases

-Portable electroretinography recordings

-Effect of common and rare genetics variants on retinal function

-Characterising retinal light and dark adaptation in health and disease

Funding: Wellcome Trust, Fight for Sight, Birdshot Uveitis Society, Thomas Pocklington Trust, Moorfields Eye Charity

My Part II research students in 2020 presented their work nationally and internationally: Remi Rufus-Toye received a Rob Clarke Abstract Award at the Future Physiology meeting of the Physiological Society; Megan Margetts received the Eberhard Dodt Memorial Award at the annual symposium of the International Society for Clinical Electrophysiology of Vision.
