In 2017, Dr. Ryan O'Hare Doig completed his Ph.D in Neuroscience and Physiology at the University of Western Australia. During his PhD,  Ryan developed and optimised a combinatorial treatment strategy incorporating pharmacotherapeutics for the treatment of Central Nervous System (CNS) injury. Ryan’s combinatorial strategy has been assessed in a clinically relevant model of spinal cord injury (SCI), traumatic brain injury and concussion, demonstrating significant functional recovery and tissue sparing, crucial for the translation of his research into clinical trials. He has a wealth of experience in various innovative and analytical techniques to demonstrate biochemical, molecular and gross anatomical changes that occur following CNS injury. Ryan 's early research career has focused on understanding the pathophysiology of secondary degeneration following neurotrauma to the CNS with a particular focus on spinal cord injury (SCI).

In 2017, Ryan joined the South Australian Health & Medical Research Institute (SAHMRI) and the Neil Sachse Centre for Spinal Cord Research, to provide his expertise in SCI, which he now leads as the acting non-executive Director, and head of the SCI Research Lab Group.  Since joining SAHMRI, Ryan has developed a research programme with three distinct themes: Discovery, diagnostics and therapeutics. These themes involve several large-scale projects, all of which have attracted substantial additional external funding (e.g. AOSpine, Neurosurgical Research Foundation, Lifetime Support Authority, SpinalCure) and internal funding University of Adelaide and SAHMRI (~$5.63m as CI, ~$3.87m as AI), respectively, across 12 competitive grants. This has led to the development of several pre-clinical research studies in small and large animal models, the approval of two world-first early phase clinical trials (ACTRN1262200073374 & ACTRN12618001946202), and the establishment of South Australia's only pre-clinical stem cell tissue engineering platform (with Adelaide Medical School, School of Biomedicine, School of Electrical and Electronic Engineering, and School of Chemical Engineering and Advanced Materials) actively seeking a cure for SCI. 

Research Interests

  • Neurotrauma
  • Neuropharmacology
  • Molecular Biology
  • Nuclear imaging (PET/CT)
  • Functional imaging (fMRI)
  • Nanomedicine
  • Inflammation
  • Oxidative stress
  • Stem cell biology

My research lab actively works on developing advanced functional and molecular imaging techniques and protocols to provide a 'live-feed' of the injured spinal cord by accurately mapping biomarkers of spinal cord pathology and quantifying dysfunction following acute and chronic SCI. My research goal is to develop a functional and molecular clinical imaging pipelines that will change how we diagnose and treat SCI, and ultimately lead novel targets for therapy to the improve quality of life of SCI individuals and their families.  

Current Projects Focus on:

  • Characterising the theranostic potential of neuroinflammation.
  • Mapping biomarkers of pathophysiology, sensorimotor and autonomic and function/dysfunction following SCI using advanced non-invasing neuroimaging techniques such as PET-CT, DTI and fMRI.
  • Developing novel techniques to improve stem cell therapeutic potential following engraftment in spinal cord tissue.  
  • Assessing the exposure risks of acute SCI patients that influence changes in the gut-inflammatory axis
  • Assessing nanomedicine techniques for the treatment of respiratory dysfunction following SCI

 

Research projects available:

Research Project 1

Project Discovery – The 18-kDa translocator protein radioligand [18F]GE-10 as a diagnostic and prognostic biomarker following spinal cord injury

Project description: One of the many consequences of spinal cord injury (SCI) is acute post-traumatic neuroinflammation. Understanding how particular biomarkers of neuroinflammation progress over the course of injury is imperative for tracking and predicting outcomes, providing accurate diagnosis and prognosis, and choosing and monitoring appropriate therapeutic interventions for SCI injured patients.

This study proposes to investigate whether positron emission tomography (PET) imaging of radioligands (e.g. [18F]GE-180) will serve as a robust biomarker to discriminate innate and adaptive inflammatory responses during acute and chronic phases of SCI, respectively.

Projects available for: Masters and/or PhD
Location:  SAHMRI, Royal Adelaide Hospital
Research project start: Current, ongoing.

Research Project 2

Project SCIN (Spinal Cord Injury Neurosexuality) – Developing a biological understanding of sexual health following spinal cord injury

Project description: Sexual health is a high priority for men and women with spinal cord injury (SCI). However, our understanding of the biological basis of sexual dysfunction in this context is still preliminary and there is no consensus treatment guideline or evidence-based treatment plan. This study proposes to perform detailed clinical assessment comparing the spared neurological and autonomic functions of men and women with complete SCIs with quantitative fMRI (functional magnetic resonance imaging) read-out of cord and brain activity. This will enable evaluation in real-time and help us to elucidate the functional nature of psychogenic sexual response.

Projects available for: Honours, Masters and/or PhD
Location: SAHMRI, Royal Adelaide Hospital
Research project start:  Ongoing.

Research Project 3

Project Bridge - Bridging the gap between regenerative medicine and spinal cord injury

Project description: The human spinal cord has limited capacity for spontaneous regeneration. Regeneration and replacement of neurons and glia that undergo cell death after SCI are the main goals of all stem cell-based therapies for SCI. However, stem cells typically show poor survival and/or differentiation under the severe conditions of SCI. Thus, translation from bench-to-bedside is clearly hindered by the lack of understanding of stem cell survival and stem cell differentiation pathways following delivery/transplantation.

This research project uniquely explores novel techniques to pre-conditioning dental pulp stem cells to promote enhanced stem cell survival and neural regeneration.

Projects available for: Third Year, Honours, Masters and/or PhD
Location: SAHMRI, University of Adelaide
Research project start: July 2019, on-going.

Research Project 4

Project Bridge - Day One to 365 (DOT365) Pilot Study - Understanding the microbial risks of neuropathic pain during the first year of spinal cord injury

Project description: Recently, it was discovered that gut dysbiosis and consequent changes in the gut microbiome influences neuropathic pain through inflammatory pathways. Similarly, it is understood that exposures to medications, diet and lifestyle factors are strongly associated with changes in the gut-microbiome and inflammatory axis. In the first 12 months following SCI, patients will be exposed to numerous modifications in both their lifestyle and environmental factors. However, to this date, no one has explored how such exposure-risks may influence changes in the gut-inflammatory axis, and thus lead to the onset of comorbidites (e.g.Neuropathic pain). Therefore, we propose an innovative observational pilot study, assessing the exposure-risks of acute SCI patients, to determine their effects on the gut-immune axis and neuropathic pain. This proposal brings together an investigative group of E/MCR research leaders with Clinical expertise in the fields of Neurotrauma, Neuroinflammation and Microbiome and Host Health. 

Research Project 5

The BREATH delivery project - Biodegradable Respiratory Enhancing nAnoparticle conjugates for THeophylline delivery and treatment of respiratory dysfunction following SCI

Project description: Respiratory dysfunction following SCI is the leading cause of morbidity and mortality in SCI patients and remains without a cure. Whilst various clinical trials have attempted to target respiratory dysfunction through drug interventions, they often require large doses of systemic drug delivered to patients who ultimately suffer low therapeutic benefit and highly intolerable side effects. Therefore, there is a critical need to pursue alternative and novel methods for treating respiratory dysfunction in SCI patients. Our breakthrough research will provide a new alternative for drug delivery using biocompatible nanoparticle delivery through a world first targeted nanomedicine approach. This study aims to engineer newly synthesised nanoparticles (NPs) with biodegradable materials, to test the hypothesis that theophylline drug-carrying NPs can selectively transport and release drugs in neurons for the effective treatment of acute respiratory dysfunction following SCI.
