I completed first degree (2008) and masters degree (2011) in Human nutrition in Tanzania. In 2015 I was awarded the Commonwealth scholarship and joined University of Surrey for PhD studies in the Department of Nutritional Sciences. My PhD research focused on understanding the role of nutrition, body composition and inflammation in responses to anaemia management therapy among haemodialysis patients. In 2018 i was awarded the Schlumberger Foundation fellowship and continued researching on the feasibility of low impact exercise intervention - facilitated with activity tracking devices on haemodialysis patients.
I joined the School of Health Sciences from January 2020 for a seven months post funded by HEIF to assist with the research activities of Digital health research group. In November 2020, I was appointed as the Post-doctoral Research Fellow in Digital Innovation for NIHR ARC Kent Surrey and Sussex.
Development and evaluation of Digital health interventions to improve delivery and access to health care services to the deprived/hard to reach communities, Black and ethnic minority communities.
Digital health offers for dietetic services and management of long-term conditions such as Diabetes, Cardiovascular disease and Chronic kidney diseases.
Digital divide and inclusivity
Anaemia is high prevalent among haemodialysis patients in Tanzania despite them being on Erythropoietin therapy. We conducted a cross-sectional study to investigate the relationship between nutritional indices, dietary intake, body composition and anaemia status of haemodialysis patients receiving erythropoietin therapy in Tanzania.
The previous study conducted in Tanzania suggested the association between body composition (the amount of body fat and muscle mass) and iron status among haemodialysis patients on erythropoietin therapy. We conducted a longitudinal study to investigate further on this relationship in the UK cohort.
Haemodialysis patients has high levels of physical inactivity. This eventually reduce their muscle mass, physical functioning and total quality of life. Physical Exercise has found to be beneficial in improving muscle mass, physical functioning, dialysis clearance and inflammation. This study was conducted to test the feasibility of low impact - flexible form of exercise combining both aerobic and resistance training for optimal impact. In this study, video was created and used to demonstrate the exercises - giving flexibility to individuals to exercise at their chosen time. Activity tracker was used to monitor participants' step counts.
There is growing adoption of technology-led health solutions. Technology has great potential to improve the delivery and access to health care services but they need to be led by research evidence. The fast paced evolving nature of technology presents methodological challenges to the evaluation studies. We are conducting a scoping review of the literature to document the research methodologies used and their limitations in evaluating digital health interventions. The aim is to identify the robust methodologies for evaluation of digital health interventions
