Background

Under Professor Pardhan’s strategic leadership, supporting a multinational and multidisciplinary team of researchers in clinical and public health research, ARU's Vision and Eye Research Institute (VERI) has received "world-leading" status through its publications and impact.

VERI's work has benefitted patients and policy makers and attracted collaborations from the World Health Organisation and the International Agency for the Prevention of Blindness. VERI researchers also lead and collaborate on various projects for the Global Burden of Diseases.

Professor Pardhan is a recipient of the First Ismaili Award for Excellence - Postgraduate category; Asian Women of Achievement Award - Professions category; Asian Jewel Award - Health Care and Education category; Vice Chancellor’s award for Outstanding Scholar; Dean’s Award for Research; and Vice Chancellor’s Award for Outstanding Research Impact.

Prof Pardhan has published 180 research papers on diabetic retinopathy, low vision, dual sensory loss, auditory cues in vision impairment, ageing and visual short-term memory and COVID-19, having won grants from the EU (Horizon 2020, Marie Curie), NIHR, NHS, College of Optometrists, Global Challenge Research Fund, Newton Fund, and various national and international Charities Including Lions Club International and Royal National Institute for the Blind (RNIB).

Prof Pardhan has developed research projects and published with University of Cambridge, as well as collaborative partners in India, China, Thailand, Nepal, Mexico, Spain, the Netherlands and more. She is also a Global Burden of Disease collaborator.

Prof Pardhan led the REF2014 submission for Vision on behalf of VERI, receiving "world-leading", "internationally excellent", and "internationally recognised" scores. She also led the submission on Vision for REF2021.

Her research has benefitted over 110,000 people in the UK, India, China, Nepal and Thailand, and was submitted as one of the two impact case studies in REF2014 (receiving 100% world leading and internationally excellent scores) and one of five impact case studies in REF2021.

She is passionate about reducing health inequality and has worked with stakeholders within communities in the UK and Asia to produce culturally appropriate awareness programs which have reduced the risk of blindness due to diabetic retinopathy.

Prof Pardhan is regularly invited to disseminate her research to newspapers and TV. She has been interviewed by the BBC, ITV and various local radio stations. Her research has made a significant contribution to increasing the knowledge base in vision and eye, including diabetic retinopathy, in South Asians and other optometry research.

Her paper ‘Sore eyes as the most significant ocular symptom experienced by people with COVID-19’, published in BMJ in 2020, was covered by over 100 local and international national newspapers (347,899,530 visits in Dec 2020) and is in the top 5% of all research outputs scored by Altmetric.

Prof Pardhan sits on the Editorial Board for Ophthalmic and Physiological Optics, the Journal of Personalised Medicine, and Frontiers in Public Health. She regularly reviews for journals, national and international grants, and reader and professorial appointments both for UK and international universities including Hong Kong Polytechnic University and University of Malaysia.

She has supervised 17 Research Fellows and 14 PhD students to completion and has been an examiner for 13 PhD students. She serves on two working groups (Diabetic Retinopathy and Low Vision) for the International Agency for the Prevention of Blindness.

Prof Pardhan is an active member of the Women in Vision UK network, having given invited talks on 'Women in Leadership’ in the UK and USA, and invited editorials on 'Breaking the glass ceiling in academia', 'Vision scientists breaking the glass ceiling' and a podcast, 'Blazing the trail for women in vision science', leading to her being included on The Ophthalmologist Power List 2019 as a Champion of Change, one of ten people in 2019 to be recognised as such for her work in improving equity for women in academia. Prof Pardhan has given talks at conferences in Nepal, India, USA, China, Hong Kong, UK, Pakistan, Malaysia, Netherlands, Tanzania, Canada, Singapore, Australia and Germany.

Prof Pardhan was appointed to be on the Assessment Panel for REF2021 for Allied Health, providing her expertise on research outputs submitted by all higher education institutions (HEIs) in the UK. She is a member of our Safe and Inclusive Communities research theme.
