Cellular & Molecular Neurodegeneration

The Cellular and Molecular Neurodegeneration Laboratory investigates the cause and potential treatments for brain diseases including dementia (Alzheimer’s disease), motor neuron disease (amyotrophic lateral sclerosis) and Parkinson’s disease. These disorders (collectively known as neurodegenerative diseases) are a growing health issue in Australia and worldwide, with few treatment options available. In order to gain a better understanding of these diseases and develop new therapeutic approaches, the research team is currently developing new human brain cell culture methods for microglia, brain endothelial cells, organoids (mini-brains), and olfactory (nasal) cells.

The lab is utilising these new 2D and 3D human brain cell models to understand brain disease pathways, and the impact of environmental factors such as air pollution, SARS-CoV-2, and bushfire smoke on brain health. We have also established platforms for drug screening to identify potential new therapeutics for treatment of brain diseases.


  • 2D and 3D culture models of human microglia from Alzheimer’s disease, motor neuron disease and Parkinson’s disease
  • 2D and 3D cultures models of the blood-brain barrier
  • organoid (mini-brain) models of Alzheimer’s disease
  • olfactory (nasal) cell models of Alzheimer’s disease
  • impact of bushfire smoke and other forms of air pollution on brain health and disease
  • development of an olfactory cell assay for bushfire smoke impact on human health
  • improving drug delivery with focused ultrasound to transiently open the blood brain barrier
  • development of novel metal-drugs for treatment of neurodegenerative diseases

Olfactory stem cells for investigating the causes and progression of dementia

This project is suitable for a PhD or Honours student. BACKGROUND With no clinical success yet achieved from amyloid-targeting strategies, there is an urgent need to gain new insights and develop effective treatments for people who have dementia. New stem cell-based approaches have generated much excitement in dementia research with the potential to study patient-derived […]

Generating Alzheimer’s microglia for testing patient responses to immune-modulating compounds

This project is suitable for a PhD or Honours student. Alzheimer’s disease is anticipated to affect 100 million patients with an annual cost of US$1 trillion by 2050. Promising amyloid-clearing therapies have failed to translate to clinical outcomes, and new approaches targeting the underlying molecular pathways of Alzheimer’s disease are urgently required. There has been […]

Development of metal-based therapeutics for neurodegenerative diseases

PhD project but may also be considered for an Honours project Biological trace elements, also known as trace minera, or biometals include copper, zinc, iron, selenium and manganese. These and other biometals have essential roles in many areas of brain function including energy metabolism, transcription factor activity, antioxidant regulation and synaptic signalling. During ageing and […]

Generating patient-derived microglia to investigate neuroinflammation in MND

This project is suitable for a PhD or Honours Student. This project will build important new tools for understanding the role of the immune system in amyotrophic lateral sclerosis (ALS), a form of motor neuron disease (MND). Inflammatory responses by the resident brain and spinal cord immune cells (microglia) have an important role in ALS/MND […]
