    Interests

    I investigate human retinal function in health and disease, using electrophysiology and complementary approaches including retinal imaging, genetic investigation and machine learning. I am Professor of Retinal Neuroscience at University College London. My research is based at multiple sites including UCL, KCL, Moorfields Eye Hospital, St Thomas' Hospital. I supervise Part II research projects based at PDN. 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, including variants associated with myopia; 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. In 2022, my PhD student, Xiaofan Jiang, received the Eberhard Dodt Memorial Award (International Society for Clinical Electrophysiology of Vision) and the Worshipful Company of Spectacle Makers Master's Medal.
