Dr Raju Sapkota, B.Optom, M.IOVS, PhD

Raju Sapkota Anglia Ruskin University Untitled Page

Dr Raju P Sapkota obtained his bachelor's degree in Optometry from Nepal in 2002.

Following two-and-a-half years' service as an optometrist at a health institute in Nepal, Dr Sapkota came to the UK to pursue higher education. He obtained his Master's degree in Investigative Ophthalmology and Vision Science (IOVS) from the University of Manchester in 2006, and a PhD from Anglia Ruskin University in 2010. Since then Dr Sapkota has been working as a post doctoral researcher in the Vision and Eye Research Unit at Anglia Ruskin University's Postgraduate Medical Institute.

Research interests

Dr Sapkota's research interests range from purely clinical domains such as amblyopia and refractive status of cataract-operated patients to more theoretical ones such as binocular summation, exta-foveal perception, visuo-spatial short-term memory, eye movements, and attention.

In his current research, Dr Sapkota is investigating the effect of age on visual short-term memory including unimodal, polymodal and cross-modal binding, with an aim of developing a new screening tool for early detection of Alzheimer's disease. This research is funded by Patrick Geoghegan Health & Wellbeing grant, Anglia Ruskin University (in collaboration with South Essex Partnership University NHS Foundation Trust).
