Time-space resolved photoelectron emission to control molecular processes. This project aims to resolve simultaneously the timing and space localisation of photoelectron emission from atoms and molecules as a means for targeted breaking of molecular bonds. Existing techniques determine the timing and spatial characteristics of photoemission independently.

This project aims to resolve simultaneously the timing and space localisation of photoelectron emission from atoms and molecules as a means for targeted breaking of molecular bonds. Existing techniques determine the timing and spatial characteristics of photoemission independently. The simultaneous time-space resolution will allow for the precise manipulation of photoelectrons by a sequence of phase-stabilised laser pulses, a technique known as coherent control. The benefit of this project will be the coherently controlled breaking of molecular bonds in oxide, carbonyl and hydrocarbon molecules. The outcome will be a significant step forward in driving complex photochemical reactions in industry.Read moreRead less

Summary
Atomic physics as a probe for fundamental physics and dark matter. The Standard Model is extremely effective at describing the fundamental particles and interactions, but is known to be incomplete. This project aims to uncover new signatures of physics beyond the Standard Model that may be observed in atomic experiments. This project expects to generate new knowledge to help unravel the mystery of dark matter, which accounts for the majority (85%) of the matter in the universe. Expected outcomes ....Atomic physics as a probe for fundamental physics and dark matter.

This project aims to uncover new signatures of physics beyond the Standard Model that may be observed in atomic experiments. This project expects to generate new knowledge to help unravel the mystery of dark matter, which accounts for the majority (85%) of the matter in the universe. Expected outcomes include extending theoretical atomic physics methods, calculating new observable atomic effects, and combining these with experiments to probe fundamental physics and search for dark matter. These outcomes would contribute to the expanding knowledge in the fields of atomic and fundamental physics.Read moreRead less
Non-equilibrium presolvation electron processes at the gas-liquid interface. The interaction of low-temperature plasma electrons with liquids has served as a reducing agent in various technological applications in water treatment, agriculture, biofuels and medicine. Predictive control of the plasma-liquid interface is essential to unlocking the potential of these applications, and this has been limited by the absence of the relevant non-equilibrium transport theory describing electrons at the pl ....Non-equilibrium presolvation electron processes at the gas-liquid interface. The interaction of low-temperature plasma electrons with liquids has served as a reducing agent in various technological applications in water treatment, agriculture, biofuels and medicine. Predictive control of the plasma-liquid interface is essential to unlocking the potential of these applications, and this has been limited by the absence of the relevant non-equilibrium transport theory describing electrons at the plasma-liquid interface together with fundamental data describing electron interactions with liquids. The project will develop a state of the art presolvation electron transport model informed by world first measurements of electron cross-sections for radicals and liquids and apply it to model plasma electrochemistry processes.Read moreRead less
Placental nutrient transport shows how complex traits evolve. This project aims to use amino acid transport in the vertebrate placenta as a model to demonstrate how genes are recruited and modified to produce a major organ. Using an innovative combination of a new technology, selected reaction monitoring, and transcriptomic and molecular approaches, plus carefully selected Australian species pairs, this project will study the evolution of a complex trait (placental amino acid transport).

Combining biomechanics and movement ecology of kangaroos and relatives. Kangaroos and their relatives are unique in their body form, hopping gait and by the fact that increased speed does not come at an increased energetic cost. This project aims to build 3D musculoskeletal models to understand how muscles and tendons interact, enabling greater distances to be travelled using less energy. Further, it will use animal tracking devices and machine-learning tools to quantify movements in the wild. T ....Combining biomechanics and movement ecology of kangaroos and relatives.

Phenotypic plasticity of reef fish vision in a changing world. This project aims to investigate why fishes have more colour vision channels than any other vertebrate on the planet by studying representatives from the most vibrant ecosystem on earth, the Great Barrier Reef. It is currently not clear how vision is controlled on the molecular level and how this translates to the performance and survival of an animal.

This project aims to investigate why fishes have more colour vision channels than any other vertebrate on the planet by studying representatives from the most vibrant ecosystem on earth, the Great Barrier Reef. It is currently not clear how vision is controlled on the molecular level and how this translates to the performance and survival of an animal. Through an innovative approach to understanding colour vision and animal behaviour, this project expects to advance Australia’s leadership in neuroscience and ecology, while also increasing the capacity for international collaborations. Beyond the scientific benefit, it will create public awareness about an endangered ecosystem, inform reef guardianship and may inspire new sensory technology.Read moreRead less

Despite their importance, we don’t understand how foot shape and structure facilitates upright locomotion.This DECRA aims to explore the relationship between foot morphology and foot function. I will close a large knowledge gap by applying novel experimental and shape modelling approaches to provide unprecedented insights into human foot function. The primary expected outcome is a detailed understanding of how foot shape and structure influences our ability to walk and run. This research will create a paradigm shift in how we think about feet in the context of human evolution, human athletic performance and athletic footwear design.Read moreRead less
