This project aims to develop ground-breaking network models of urban traffic systems to build a new congestion control framework. The purpose of network modelling is to capture the interdependence between different parts of traffic systems, which facilitates studying congestion cascade within the network. The project expects to generate next generation of network models for more effective congestion control. Expected outcomes include novel congestion control technologies that adjust traffic signals in real-time to optimally utilise the available road space. This should provide significant economic and environmental benefits to Australians by easing traffic jams.Read moreRead less
Networks: New links between spectrum, dynamics, rewirings and applications. Modern network science has transformed the study of complex systems and led to innovations in many disciplines. This project intends to develop breakthrough theories for control of complex networked system behaviour via interventions of the link-rewiring type. New approaches will be developed for non-random, assortative and/or structured networks, which are poorly understood and difficult to deal with, despite being the ....Networks: New links between spectrum, dynamics, rewirings and applications. Modern network science has transformed the study of complex systems and led to innovations in many disciplines. This project intends to develop breakthrough theories for control of complex networked system behaviour via interventions of the link-rewiring type. New approaches will be developed for non-random, assortative and/or structured networks, which are poorly understood and difficult to deal with, despite being the real-world norm and despite their impact. The results will give new insights into epidemic outbreaks and their impact on vulnerable groups (e.g., elderly and indigenous), and provides methods to enforce resilience of infrastructure networks such as power grids, thereby providing significant economic and societal benefits.

The expected outcome is a practical technology for industry applications, such as smart power grids. This should increase the reliability and resilience of the electricity networks against faults and cyber attacks.

New technology developed by Australia, Sweden and the United States will be applied to major questions about the application of relativistic quantum mechanics to atomic structure and dynamics and spectroscopy, especially including critical issues in quantum electro-dynamics for atomic physics and applications. Discrepancies in quantum electro-dynamics have dominated international debate for decades, with claimed explanations annually failing to reveal the cause. Also a pattern of discrepancies has been seen at X-ray energies in first row metal atoms, with a similar sign and magnitude. A combined experimental an theoretical investigation will aim to reveal new light on these anomalies and serve to develop our understanding of the universe.Read moreRead less

Imaging the youngest planets. Over 5000 exoplanets have been discovered, demonstrating that planet formation is a robust and widespread process. But we do not know how these planets, including those in our solar system, formed. Our group at Monash pioneered a new technique for detecting "baby" planets --- observed still embedded in the disc of gas and dust from which they are born.

Over 5000 exoplanets have been discovered, demonstrating that planet formation is a robust and widespread process. But we do not know how these planets, including those in our solar system, formed. Our group at Monash pioneered a new technique for detecting "baby" planets --- observed still embedded in the disc of gas and dust from which they are born. The project aims to characterise the youngest detected exoplanets with the world's largest telescopes, including time already awarded on the James Webb Space Telescope. We will image these planets, and model their birth in 3D. The project will develop state of the art computer algorithms for simulating fluid flow and data analysis technics that can be applied to problems here on Earth. Read moreRead less

This project expects to generate new knowledge on how binary stars, exoplanets, and stellar mass black holes are formed. Expected outcomes of this project include tight constraints on binary star models, new discoveries of neutron stars and black holes that are a few times more massive than the Sun, and samples of stars that do, and do not, host exoplanets. This should provide significant benefits including a catalogue of companion properties for billions of sources, new understanding of how stars die, as well as the first control sample of stars without planets to help understand how and why planets form.Read moreRead less
