Researcher

My Expertise

Expertise: As a translational cell biologist, I research a key structural feature of cells, the actin/tropomyosin cytoskeleton, and develop therapeutics that target the cytoskeleton in a range of human conditions including cancer, platelet dysfunction, lens opacification and cataracts, chronic inflammatory bowel disease and fibrosis. My research is in the emerging multidisciplinary field of mechanobiology that examines the relationship between the physical structure of cells and their environmental signals and forces. My work involves collaborating with academic, health and industry partners within Australia and internationally.

Approaches: I use and develop state-of-the-art imaging modalities to visualise actin/tropomyosin structures in cells, including live cell imaging, intravital subcellular microscopy ISMic), intracellular intravital single molecule imaging (iSiMM), and correlative cryo-electron tomography. I develop tropomyosin-specific reagents including antibodies and genetically modified mice for academic collaborations and commercial use to identify cell cytoskeleton structures in health and disease. I use our tropomyosin antibodies to screen human tumour microarrays for diagnostic indicators. I partner with industry to develop drugs to modulate tropomyosin for potential therapies in human conditions.

Impact: My research has resulted in the development of a platform technology

Research Activities

A potential target for anti-cancer drugs is the actin cytoskeleton; however, it has been unattainable because the toxicity associated with disabling this target has been unacceptable. The actin cytoskeleton is a desirable target because it controls many fundamental processes in the cancer cell such as cell growth, movement and interaction with the surrounding environment. We have identified a way to attack specific actin filament populations within cells by developing drugs that target specific isoforms of the actin-associated protein tropomyosin. This allows us to target actin filaments…
