About

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.

ALM Drug Therapy to reduce inflammation and scar formation after ACL reconstruction surgery: Targeting earlier return to active duty.

Indicative Funding
$1,061,864 over 4 years
Summary
Two complications of anterior cruciate ligament (ACL) reconstruction surgery are cartilage degeneration and scarring within the joint, which can prolong healing, promote pain and restrict knee movement. Our project will evaluate a new therapy known as ALM solution that can be administrered during ACL reconstruction surgery to dampen inflammation, protect cartilage and promote tissue healing within the joint. Our study has the potential to expedite a patient's return to an active duty with fewer complications.

Trauma Care in the Tropics: A Multi-centre Retrospective Analysis

Indicative Funding
$10,795 (administered by Townsville Hospital and Health Service)
Summary
High quality pre-hospital trauma care and timely access to emergency aeromedical retrievl services is paramount for an efficient, sustainable healthcare system in North Queensland. We propose to identify and classify trauma patients in the North Queensland since 2016 to assess the magnitude of the total injury burden and evaluate the chain-of-care from the prehospital environment, through patient transfer, to hospital discharge. The dataset generated will provide valuable insights into patterns of primary retrieval, trauma distribution, and service provisions and gaps.

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
Summary
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.
