Areas of Expertise: Vision and eye research
Dr Sapkota’s research expertise and interests are on diabetes and diabetic retinopathy in Asians. His other areas of research expertise are visual short-term memory, and visual function in age-related macular degeneration.
Following his two-and-a-half years' service as an optometrist at BP Koirala Institute of Health Sciences in Nepal, Dr Sapkota came to the UK. He obtained an MSc degree in Investigative Ophthalmology and Vision Science from the University of Manchester (2006), and a PhD from Anglia Ruskin University (2010). Dr Sapkota works as a Senior Research Fellow in the Vision and Eye Research Institute at our Faculty of Health, Education, Medicine and Social Care. Dr Sapkota has published findings in high-impact journals. He has presented papers at national and international conferences, and has obtained a number of research-related grants and awards.
Dr Sapkota has supervised seven research interns to date, which led to several research outputs.
