Research Experience
-
At Oxford University, U.K. I was a NIHR (National Institute for Health Research) and EFSD (European Foundation for the Study of Diabetes) clinical research fellow working in clinical diabetes research.
-
I was also a sub-investigator in numerous multicentre, and multinational trials in both diabetes and endocrinology. During this period I gained experience in performing physiological studies including insulin-glucose clamp studies, DEXA scans, and anthropometry, writing grant applications and research protocols, setting up clinical trials, applying for ethics, R&D and MHRA approval, patient screening and recruitment to clinical trials, and staff recruitment.

We undertook a pilot study of the n-of-1 methodology in type 1 diabetes, a series of single-subject, randomised, crossover studies, where patients serve as their own control, comparing efficacy, tolerability and acceptability of interventions. They provide evidence for personalised therapeutic choices. Patients served as their own control comparing two basal insulin analogues. Patient satisfaction (primary outcome) with the n-of-1 methodology was assessed by qualitative measures (visual analogue scales, free text boxes, semi-structured interview). Secondary outcomes were ΔPAID, ΔITSQ, ΔWHO-5, ΔHbA1c, ΔGRADE. As a part of this study we used CGMS to determine patient glucose profiles to titrate insulin therapy and for patient education.

As part of the systems biology investigation of glucose metabolism and beta cell function, we proposed to study the effect of Sitagliptin on glucose response in non-diabetic and type 2 diabetic individuals using a eu- and 3-step hyperglycaemic clamp in a randomised double blind cross-over study. The Phenotypic Characteristics in Type 2 diabetes as Indices of Beta-cell Failure study aimed to understand the factors influencing the rate of beta cell failure, to analyse the association between beta cell failure and phenotypic, anthropometric, biochemical and radiological characteristics, to identify individual and clusters of characteristics in those who fail fast and those who fail slowly, and to undertake hypothesis testing of these characteristics to develop a risk assessment model for fast vs. slow failure.
