Dr. Kerry Marran

Kerry Marran is a clinician-researcher in paediatric endocrinology with a focus on type 1 diabetes management in children and adolescents. Affiliated with South African academic medical institutions, Marran’s work centers on optimizing insulin therapy and improving glycaemic control through evidence-based adjustments to injection practices and dosing strategies.

Research has explored skin and subcutaneous tissue thickness in young patients using ultrasound to inform safer insulin injection techniques. This work highlights the clinical implications of needle length, injection site selection, and technique in reducing intramuscular delivery and enhancing treatment adherence, directly influencing practical diabetes care guidelines.

Additional studies investigate postprandial glucose dynamics, challenging the assumption of a linear carbohydrate-to-insulin ratio and demonstrating complex glucose responses to increasing carbohydrate loads. Although based on limited available publications at present, the research reflects a strong commitment to improving therapeutic precision and metabolic outcomes in paediatric diabetes.
