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 the Vision and Eye Research Unit (VERU) based within the Postgraduate Medical Institute. Under her leadership VERU has developed into an international research centre. She supports and facilitates vision and eye research within the different departments of Anglia Ruskin University. She has also built a team comprising four consultant ophthalmologists, as part-time professors, and post-doctoral 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 (84% rated as world class/internationally excellent). The impact and reach of VERU's research activities was rated as 100% world class and internationally excellent.

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).
