Teaching interests

I teach a range of clinical and professional dietetic skills across the dietetics programme with particular interest in paediatric dietetics, neurology (use of ketogenic diet therapy), communication skills and behaviour change. I supervise MSc student projects; supporting students to achieve their research goals.

Research interests

My research area of interest is the use of ketogenic diet therapy for neurological conditions but predominantly childhood epilepsy.

I am leading a study to develop a set of Core Outcomes for Refractory childhood Epilepsy treated with Ketogenic Diet Therapy (CORE-KDT). The study will identify core outcomes to be measured in clinical effectiveness trials but will also guide health care professionals when undertaking audit or service evaluation in clinical practice. Parents, health care professionals and relevant charities will be consulted to ensure the core outcome set reflects the interests of all and facilitates future decision making. 

A list of outcomes commonly used in the literature has been identified via a scoping review. Interviews with 20 parents and caregivers to a child with epilepsy treated with ketogenic diet have identified the outcomes of importance to them, including new outcomes not previously identified in the scoping review. 

Recruitment is ongoing for the final phase (launch October 2020) Delphi Survey of parents, care givers, healthcare professionals and researchers to agree a core set of outcomes for childhood epilepsy treated with ketogenic diet.
