This Fellowship aims to advance understanding of the endothelial cell surface, a key tissue barrier, and its interactions with nanomaterials. Enabled by cross-disciplinary collaboration, it expects to develop knowledge in matrix biology of the cell surface and materials as well as new methods to analyse their interactions. This is expected to unravel causal relationships between nanomaterial features and interactions at the cell surface which will be integrated to engineer optimised materials. This will address the current and critical challenges of nanomaterial technologies in the efficient and targeted interactions with cells with long-term benefits for the consumer, biotechnology and healthcare sectors.Read moreRead less
Investigation of novel mechanisms for the regulation of sperm-oocyte interactions. Through work with national and international collaborators, this project aims to provide unprecedented insights into how spermatozoa recognise and bind to an oocyte. The approach is based on strong preliminary data indicating that molecular chaperones play a key role in the functional remodelling of the spermatozoon by promoting the assembly of multimeric oocyte receptor complexes.

Through work with national and international collaborators, this project aims to provide unprecedented insights into how spermatozoa recognise and bind to an oocyte. The approach is based on strong preliminary data indicating that molecular chaperones play a key role in the functional remodelling of the spermatozoon by promoting the assembly of multimeric oocyte receptor complexes. Through the use of state-of-the-art cell biology and proteomic technologies, the project aims to investigate how molecular chaperones orchestrate these changes and in doing so, improve understanding of the fertilisation cascade and open up new contraceptive strategies.Read moreRead less

Regulation of 3D Cell Migration by Microtubule-Dependent Processes. The overarching aim of this research is to elucidate the molecular mechanisms that cells use to move in 3D environments: a basic biological function essential to development and homeostasis. During these processes, cells interact with their surroundings where they translate biophysical forces into biochemical signals to adapt their shape to move. This requires distinct signalling, controlled in space and time, to regulate the cr ....Regulation of 3D Cell Migration by Microtubule-Dependent Processes. The overarching aim of this research is to elucidate the molecular mechanisms that cells use to move in 3D environments: a basic biological function essential to development and homeostasis. During these processes, cells interact with their surroundings where they translate biophysical forces into biochemical signals to adapt their shape to move. This requires distinct signalling, controlled in space and time, to regulate the crosstalk between organelles and the cytoskeleton. To date, the role of microtubules remains elusive. Using interdisciplinary approaches combining advanced imaging technology with novel cell biology methods, the project aims to uncover fundamental knowledge about how cells interact with their environment.Read moreRead less

The results are being applied to new medical alternatives for infertile patients and new diagnostics and therapeutics for patients with metastatic cancers. The information is also being applied to improve reproductive efficiency in animal production industries.Read moreRead less
Molecular dissection of malaria parasite motility and host-cell invasion across the lifecycle. Malaria parasites move in a unique way, gliding across cell surfaces and infecting host cells using a unique molecular motor. This research aims to understand the molecular mechanics behind parasite movement and use this to develop novel drugs that might throw a spanner in the parasite motor, blocking movement and thereby preventing malaria disease.
Mimetics and small chemical compounds for hemopoietic stem cell mobilisation. This project will result in the design and synthesis of new chemical compounds that could be used clinically to help collect blood stem cells for bone marrow transplantation. For patients this will mean more effective and less painful ways to collect stem cells and better transplant outcomes. There is a large, ongoing international market for this type of drug and likelihood of significant financial benefit.
Genetic dissection of cardiac morphogenesis. The human heart is critical for survival and yet, despite its importance, we still lack a basic understanding of how it forms. This project aims to discover new genes involved in cardiac development so we can understand how to build a heart. Armed with this information, this research will assist in devising strategies for the repair of congenital and acquired heart disease.
