Background

Professor Shahina Pardhan is the Director of the Vision and Eye Research Institute (VERI) based in our new School of Medicine. All vision and eye research carried out by VERI’s core staff as well as by staff from different departments at Anglia Ruskin (Vision and Hearing Sciences, Sport Sciences, Psychology, Computing) are part of the Institute. Working with consultant ophthalmologists, this brings in a rich mix of different expertise across Anglia Ruskin University and the NHS to address vision and eye problems. VERI also collaborates with a large number of world leading laboratories across the world. Under Professor Pardhan’s leadership, the Institute has developed into an international research centre. The impact from VERI’s research was rated as 100% World Class and Internationally Excellent in REF2014.

Professor Shahina Pardhan was appointed as the first female professor of optometry in the UK (2001). Shahina current research areas include diabetic retinopathy, low vision, ageing and visual short-term memory. An established scientist, she has published just under 50 publications within this REF2021 period (2014-2020).

Shahina is a recipient of the Asian Jewel Award – Health Care and Education category (2005), the Asian Women of Achievement Award – Professions category (2001) and the first Ismaili Award for Excellence in the Postgraduate category (1992).
