Summary
Regulation of cell reprogramming to pluripotency by complex topographies. This project aims to use nanotopography approaches to improve the efficiency of generating induced Pluripotent Stem Cells (iPSCs) by changing cell behaviour at biomaterial surfaces. The significance is that iPSCs have enormous potential in stem cell therapy, regenerative medicine, and disease-specific treatment, with the potential to replace other stem cell types. The expected outcomes are that cellular reprogramming proce ....Regulation of cell reprogramming to pluripotency by complex topographies. This project aims to use nanotopography approaches to improve the efficiency of generating induced Pluripotent Stem Cells (iPSCs) by changing cell behaviour at biomaterial surfaces. The significance is that iPSCs have enormous potential in stem cell therapy, regenerative medicine, and disease-specific treatment, with the potential to replace other stem cell types. The expected outcomes are that cellular reprogramming process for iPSCs generation will be improved and the canonical reprogramming factors might be reduced using surface nanotopographies of self-assembled colloidal crystals. The benefits are the promotion of productivity, the reduction of costs, and the application of iPSC derivatives, aimed at future clinical applications.Read moreRead less
Future neural electrodes: probing the electrical activity of nerves using 3D graphene networks. This research aims to develop a totally new type of neural electrode that will for the first time, allow reliable and long-term stimulation and recording.

Given the demand for point-of-care drug delivery, micro/nano-encapsulation and biomaterials synthesis, the research will be beneficial to the pharmaceutical industry and spin-off/start-up microfluidic businesses interested in commercially developing these devices. It is intended that the work will improve quality of life by advancing biomaterials technology and by making medical treatment more readily accessable, portable and more efficient. For patients, the proposed drug delivery device can help prevent sudden initial bursts of dose during administration, which could potentially have fatal consequences.Read moreRead less
Designing functional biomaterials with superior cellular interactions. This proposal aims to make a new class of biomaterials that direct important cellular functions such as adhesion, proliferation, and differentiation. This will be achieved by developing materials that leverage a previously unexplored mechanism that was recently identified in my lab: the co-engagement of integrin and syndecan-4 cell receptors. We will use these biomaterials to 1) fabricate 3D printed tissue engineering scaffo ....Designing functional biomaterials with superior cellular interactions.

Bone regulation - cell interactions to disease. Many bone disorders such as osteoporosis, Paget's disease and chancer related bone diseases are directly related to disruption of communication pathways between bone cells leading to imbalances in bone remodeling. Although these disorders are common and cause considerable suffering, in most cases little is known about the mechanisms responsible for dysfunctional remodeling. Understanding the communication network between bone cells and their inter ....Bone regulation - cell interactions to disease. Many bone disorders such as osteoporosis, Paget's disease and chancer related bone diseases are directly related to disruption of communication pathways between bone cells leading to imbalances in bone remodeling. Although these disorders are common and cause considerable suffering, in most cases little is known about the mechanisms responsible for dysfunctional remodeling. Understanding the communication network between bone cells and their interaction with drugs is essential in order to develop new therapies and to effectively design novel biological compatible bone implants. This research proposal closely aligns with national research priority two, i.e., promoting and maintaining good health (ageing well, ageing productively).Read moreRead less

This project will develop materials whose stiffness can be reversibly increased and decreased by the simple application of light, and use these to build knowledge of how stem cell fate is regulated. The influence of mechanical cues on the structure and organisation of the nucleus will be determined. Expected outcomes are new synthetic and light-reversible culture materials, and fundamental insights into how forces change the nucleus to alter stem cell aging and fate. The findings will provide critical information required for the future development of assays to measure cell potency and instructive biomaterials to drive stem cell expansion and tissue-regeneration and will have impact by underpinning future advances in stem cell technologies.Read moreRead less
