Professor Shahina Pardhan qualified with First Class Honours in Optometry from the University of Bradford in 1984 when she was also awarded the Yorkshire Optical Society's 'Best Student Prize'. In 1986, having been awarded a research studentship from the British College of Optometrists and a further scholarship from the Committee of Vice-Chancellors of the United Kingdom as a foreign student of outstanding merit, she commenced her PhD and was awarded a doctorate in 1989 from University of Bradford.

Background

In 2001 Shahina joined Anglia Polytechnic University as the first female professor of optometry in the UK. In 2009 she took up position as the inaugural director of VERU, the Vision and Eye Research Unit (now the Vision and Eye Research Institute) based in our School of Medicine.

Under Shahina's leadership, the Institute has developed into an international research centre. She supports and facilitates vision and eye research in the different departments of Anglia Ruskin University. She has also built a team comprising consultant ophthalmologists as part-time professors, and postdoctoral research fellows. Shahina led the successful Research Excellence Framework 2014 for Allied Health Professions which resulted in 100% of VERU's profile being rated as world class, internationally excellent and excellent.

Shahina’s current research areas are in diabetic retinopathy, low vision and visual short-term memory.

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).
