The Australian Centre for Complex Systems brings together leading researchers from several disciplines and institutions to conduct research on questions fundamental to understanding and managing complex systems. Its core research program, based on the theme of computation in and by networks of agents, has two interwoven strands. The science strand addresses questions about emergent properties, natural computation, and nonlinear dynamics. The engineering strand addresses issues about methodology, modelling toolkits, and management and control. Practical applications are advanced via collaborative projects that address key issues in biology, environment, and socio-economics.Read moreRead less
Genetic control of plant organ growth. Plants organs, such as leaves and petals, have a distinct size and shape reflecting differences in growth. Despite its importance, very little is known about the mechanisms that regulate growth. The objectives of this proposal are a) to test whether organ growth depends on cell-cell signalling and b) to identifying genes that regulate growth, and to characterize their molecular function.
Marsupial germ cells and genes. Germ cells are the most fascinating cells in the body, since theirs is the unique responsibility for transmitting life from generation to generation. Studies in mice have suggested that position in the embryo determines their origin, but the early embryology of the mouse is so different from that of other mammals that the events need confirming and extending in another species. The simplified embryology of the tammar wallaby makes it ideal for studying one of the ....Marsupial germ cells and genes.

Studies in mice have suggested that position in the embryo determines their origin, but the early embryology of the mouse is so different from that of other mammals that the events need confirming and extending in another species. The simplified embryology of the tammar wallaby makes it ideal for studying one of the most fundamental questions in the whole of biology: what is the basis for the primal distinction between sex and soma?Read moreRead less
How does the unilaminar blastocyst form an embryo? Marsupials are synonymous with Australia and they are scientifically amazing. An understanding how the single-layered marsupial blastocyst cells are directed to form the complex organisation of an embryo would help us understand the biology underlying the developmental potential of all cells. Understanding these processes is not only of great fundamental interest to developmental biology but also for the development of embryonic stem cell lines. ....How does the unilaminar blastocyst form an embryo?

Understanding these processes is not only of great fundamental interest to developmental biology but also for the development of embryonic stem cell lines. This research will continue Australia's high profile in reproductive biology using one of our iconic native mammals. A greater understanding of marsupial reproduction will also contribute to management of our threatened marsupial populations.Read moreRead less
Taming the intruders: the domestication of Tigger transposable elements in mammals. It has become apparent that most of the DNA that makes us what we are is actually comprised of the remnants of invading parasitic DNA acquired over time. A continual battle exists between host which tries to silence or remove this DNA, and the parasite that tries to multiply and spread. We are currently investigating an intriguing aspect of this process that involves host genomes 'domesticating' parasitic DNA to ....Taming the intruders: the domestication of Tigger transposable elements in mammals. It has become apparent that most of the DNA that makes us what we are is actually comprised of the remnants of invading parasitic DNA acquired over time. A continual battle exists between host which tries to silence or remove this DNA, and the parasite that tries to multiply and spread. We are currently investigating an intriguing aspect of this process that involves host genomes 'domesticating' parasitic DNA to provide novel functions, thereby facilitating the evolution of specific characteristics within species.Read moreRead less

Emergence of robust, stable structures via computation within natural networks. An ever-increasing challenge for modern society is the sheer complexity of vast infrastructures. Unexpected, and sometimes catastrophic, behaviour often emerges from interactions between elements of large systems.
