Staff Profile

I completed my PhD at Deakin University, Australia in 2014, investigating the molecular regulation of skeletal muscle mass in response to exercise and nutritional interventions.

Since 2015 I have been working with Professor Grainne Gorman and esteemed colleagues within the Wellcome Centre for Mitochondrial Research where I have worked in the set up and delivery of clinical trials (including CTIMPS and non-CTIMPS). I am also an accredited (ACSM) clinical exercise physiologist, prescribing personalised exercise programmes to patients with mitochondrial disease- seen at the NHS Highly Specialised Service for Rare Mitochondrial Disorders of Adults and Children, in Newcastle. 

Education & Training

Certified Clinical Exercise Physiologist – American College of Sports Medicine (ACSM)

PhD Skeletal muscle physiology/ molecular biology – Deakin University, Australia

BSc Exercise and Sports Science (1st Class Hons) – Deakin University, Australia

BSc Exercise and Sports Science – Deakin University, Australia

My research has primarily focused on better understanding the physiology of exercise intolerance in patients with mitochondrial disease, and the effect of therapeutic interventions. More recently, my research interests have expanded through direct involvement of patient care at the national mitochondrial clinic. This has provided me with an invaluable insight into the multisystemic nature of mitochondrial disease and has driving my commitment to translate clinical research into improving patient lives. In addition, I am interested in developing biomarkers to faciliate diagnosis, track disease progression and response to treatment.
