I am a Research Fellow in the Heart, Trauma and Sepsis Research Laboratory in the College of Medicine and Dentistry, at James Cook University (JCU). After graduating with a University Medal from JCU with a Bachelor of Science majoring in Physiology and Pharmacology and Biochemistry and Molecular Biology, I joined the Heart and Trauma Research Laboratory in 2008 where I undertook an MSc and PhD developing a small-volume resuscitation solution comprising adenosine, lidocaine and magnesium (ALM) for the treatment of traumatic hemorrhagic shock. More recently I completed the first trials of ALM in uncontrolled hemorrhage as well as traumatic brain injury, and continue to work with the US Military to translate ALM resuscitation fluid into the field.

United States Department of Defence - Broad Agency Award

Optimisation of Ultra-Small Volume Adenosine, Lidocaine and Mg2+ (ALM) Fluid Resuscitation and 72hr Stabilisation Drip for Uncontrolled Haemorrhage and TBI

Indicative Funding
$1,746,795 over 5 years
The resuscitation and stabilisation properties of ALM 'one-two treatment' will be investigated in rats after uncontrolled blood loss ? traumatic brain injury, and a translational arm in pigs followed for 72hrs to mimic prolonged far-forward retrieval delays. The aim is to show improved survival is associated with improved cardiac function, reduced inflammation, less coagulopathy and less secondary 'it' complications. The ALM therapy has the potential to reduce morbidity and mortality on the battlefield by buying time for treatment, stabilisation and preparedness of causalities for safer evacuation. The study also has broad-spectrum public purpose for pre-hospital trauma and aeromedical transport.
