The rapid interactions of circulating human blood platelets is critical to prevent bleeding, but can cause thrombotic diseases (heart attack, stroke). These highly regulated interactions involve specific adhesive proteins. Our studies will define factors regulating platelet interactions. Imaging the thrombotic process will quantify platelet function at an unprecedented resolution and we have a panel of new candidate reagents that will be assessed for antithrombotic potential.
Water storage in the earth's mantle - understanding the process of OH incorporation in olivine. The amount of water in the Earth's mantle is thought to be sufficient to replace the surface oceans more than ten times. Whether this water exists in a fluid, melt, or mineral is important for understanding a range of mantle properties. The entire upper mantle water budget may be accommodated at defect sites in the mineral olivine. However, defects found in natural olivine do not correspond to thos ....Water storage in the earth's mantle - understanding the process of OH incorporation in olivine. The amount of water in the Earth's mantle is thought to be sufficient to replace the surface oceans more than ten times.

The entire upper mantle water budget may be accommodated at defect sites in the mineral olivine. However, defects found in natural olivine do not correspond to those produced
experimentally. Therefore, previous conclusions on water storage in the mantle are questionable. To address this problem the mechanism of water incorporation in olivine will be investigated using experimental petrology and spectroscopy.Read moreRead less
Molecules as probes of the interstellar medium. It is one of the greatest challenges in Nature is to remotely identify what is in space. Interstellar molecules are identified by their spectra, but many features in these spectra are unknown, implying that there are many more molecules in space than we know about. With a stronger understanding of space chemistry, we could predict what should be there and verify it in the lab. Conversely, identification of these features will provide the tools to u ....Molecules as probes of the interstellar medium.

With a stronger understanding of space chemistry, we could predict what should be there and verify it in the lab. Conversely, identification of these features will provide the tools to understand interstellar chemistry. In this project we combine skills in spectroscopy and astronomy to make these molecules in the laboratory, measure their spectra and thereby identify unknown molecules in space.Read moreRead less

Fighting terrorism and crime is one of the most important and difficult tasks that requires substantial human and technological resources. This project will help to address this enormous problem by developing a new optical sensor technology for the detection and identification of traces of chemicals, explosives, drugs and biological agents. It will develop a laboratory prototype of this sensor that is expected to have superior sensitivity and operational capabilities. Thus it will noticeably contribute to practical law enforcement, air quality and environmental monitoring, counter-terrorism, air safety, border security and customs service. It will also lead to further development of nano-optics and nanotechnology in Australia. Read moreRead less

Topological wave manipulation in hybrid integrated platforms. This project aims to establish a powerful toolkit for topological wave manipulation in photonic systems interfaced with layered 2D materials. This research will address a significant problem of miniaturising photonic components for reliable and compact signal processing. The reduction in size will be achieved by engineering coupling of topological photonic states with matter in judiciously structured materials at subwavelength scales. ....Topological wave manipulation in hybrid integrated platforms.

The reduction in size will be achieved by engineering coupling of topological photonic states with matter in judiciously structured materials at subwavelength scales. The expected outcomes will include new methods of controlling light-matter waves on a chip via pattern distortions or twists of the 2D materials, without the use of strong magnetic and electric fields. These outcomes will benefit future development of high performance and energy-efficient integrated devices.Read moreRead less

In conjunction with theoretical calculations, the results from these experiments will provide the most advanced evaluation for molecular orbital imaging quality for the chemically significant targets we wish to study. This in turn will lead to the determination of more accurate physico-chemical information, including structure and bonding information, for these targets.Read moreRead less
