Horizontal convection at ocean-relevant proportions. This project aims to determine the role of buoyancy differences from solar radiation and vertical confinement. Flows created by lateral variation in heat or buoyancy are poorly understood when the horizontal length greatly exceeds the height, precisely the conditions relevant to industry and understanding the role of horizontal convection in Earth's oceans and in turn the delicate current system that maintains Earth's temperate climate. This p ....Horizontal convection at ocean-relevant proportions. This project aims to determine the role of buoyancy differences from solar radiation and vertical confinement. Flows created by lateral variation in heat or buoyancy are poorly understood when the horizontal length greatly exceeds the height, precisely the conditions relevant to industry and understanding the role of horizontal convection in Earth's oceans and in turn the delicate current system that maintains Earth's temperate climate. This project proposes computational and experimental efforts to probe the ultimate regime of heat transport in very shallow horizontal convection, benefiting humankind through improvements to future ocean and climate modelling efforts.Read moreRead less
Gravity Current Driven Smoke Dispersion In a Stratified Ambient. Smoke from bushfires transported by gravity currents, and known to occur nationwide, caused the shutdown of businesses, education and events in Canberra in 2019. Recent scientific investigations have shown that the speed of propagation and concentration of smoke in these three-dimensional gravity currents have a long term ‘memory’ of their initial configuration. In this project, high-fidelity computational and experimental techniq ....Gravity Current Driven Smoke Dispersion In a Stratified Ambient. Smoke from bushfires transported by gravity currents, and known to occur nationwide, caused the shutdown of businesses, education and events in Canberra in 2019. Recent scientific investigations have shown that the speed of propagation and concentration of smoke in these three-dimensional gravity currents have a long term ‘memory’ of their initial configuration. In this project, high-fidelity computational and experimental techniques will be used to elucidate the fundamental mechanisms of gravity current entrainment and propagation. This knowledge will set a strong foundation to improve operational forecasts of smoke transport that will allow government agencies to better respond to the negative impact of these complicated flows.Read moreRead less

Redefining the immune landscape of the human ocular surface. At the ocular surface, the cornea and limbus need to mount effective immune responses to maintain corneal transparency for clear vision. The current paradigm is that the human cornea houses the same innate immune cell subsets (dendritic cells and macrophages) as naïve mice in pathogen-free facilities. Our pilot data challenge this premise, with early evidence that innate and adaptive cells (T cells) coexist in normal human corneas. Int ....Redefining the immune landscape of the human ocular surface. At the ocular surface, the cornea and limbus need to mount effective immune responses to maintain corneal transparency for clear vision. The current paradigm is that the human cornea houses the same innate immune cell subsets (dendritic cells and macrophages) as naïve mice in pathogen-free facilities. Our pilot data challenge this premise, with early evidence that innate and adaptive cells (T cells) coexist in normal human corneas. Integrating state-of-the-art techniques, we will advance understanding of immune regulation at the human ocular surface by comprehensively defining immune cell biology and dynamics. We will define the effect of age on immune cells in these tissues, and relationships between the tear proteome and cell behaviours.Read moreRead less
