Diversity out of a hybrid zone: the interplay of reinforcement and sexual selection in the formation of new species. How are there so many different species? Understanding how new species arise is a fundamental question because it explains current biodiversity and reveals the processes that will continue to give rise to new species in the future. An integral part of any animal species is who they choose to mate with, but how mate choice evolves to create new species remains poorly understood. He ....Diversity out of a hybrid zone: the interplay of reinforcement and sexual selection in the formation of new species. How are there so many different species? Understanding how new species arise is a fundamental question because it explains current biodiversity and reveals the processes that will continue to give rise to new species in the future. An integral part of any animal species is who they choose to mate with, but how mate choice evolves to create new species remains poorly understood. Here I will be studying the processes that affect the evolution of mate choice in an Australian rainforest frog hybrid zone. This system is uniquely suitable for providing internationally important insights into the evolutionary processes that form new species.Read moreRead less

The project brings together national and international researchers to study how humans and other animals navigate: how trajectories through space are used to build maps, the neural bases of these mapping processes and how to use maps to achieve goals. The project will develop a new generation of robots that can learn about the physical spaces they work in, and create concept-mapping systems that can map and navigate information spaces. Also, it will provide new insights into the mechanisms regulating human cognition and mental dysfunctions.Read moreRead less
Neural mechanisms for human form perception. This project aims to determine if there is a single cortical mechanism underlying the human ability to discriminate and recognise objects. It has been speculated that different classes of objects, or forms require different processes. Demonstrating a single process would be a significant advance towards understanding the neural mechanisms giving rise to our ability to segment visual fields into meaningful objects and background. This research provides ....Neural mechanisms for human form perception. This project aims to determine if there is a single cortical mechanism underlying the human ability to discriminate and recognise objects. It has been speculated that different classes of objects, or forms require different processes. Demonstrating a single process would be a significant advance towards understanding the neural mechanisms giving rise to our ability to segment visual fields into meaningful objects and background. This research provides a means for testing models of the neural interactions thought to be generating human form perception and will help us discover how the visual cortex converts raw sensory input into object and form perception.Read moreRead less
The function of truncated MEK1 protein in a G2 phase cell cycle delay and in mitosis. Understanding cell proliferation. Intracellular signaling pathways controlling cell growth are often mutated in cancers and other hyperproliferative diseases. Understanding precisely how these pathways operate and how mutations of these pathways can contribute to uncontrolled growth can readily provide new targets for preventative therapies or cures. We have identified a novel mechanism regulating one compone ....The function of truncated MEK1 protein in a G2 phase cell cycle delay and in mitosis. Understanding cell proliferation. Intracellular signaling pathways controlling cell growth are often mutated in cancers and other hyperproliferative diseases. Understanding precisely how these pathways operate and how mutations of these pathways can contribute to uncontrolled growth can readily provide new targets for preventative therapies or cures. We have identified a novel mechanism regulating one component of a well studied pathway, the MAPK pathway, and new functions for this component. The contribution of this novel component to mechanisms involved in regulating cell growth previously through to be controlled by the canonical MAPK pathway could change our understanding of the fundamental mechanisms controlling cell growth.

Function of the unique mitotic form of MEK. Many of the mechanisms controlling normal cell growth and division are known, although there are an increasing number of examples of mechanism having more thn the originally defined functions. We have found that one well studied mechanism, the Ras-Raf-MEK-ERK pathway operates in a unique manner during the phase when cell division occurs, known as mitosis. Understanding this novel mechanism and identifying its function at this critical stage of cell d ....Function of the unique mitotic form of MEK. Many of the mechanisms controlling normal cell growth and division are known, although there are an increasing number of examples of mechanism having more thn the originally defined functions. We have found that one well studied mechanism, the Ras-Raf-MEK-ERK pathway operates in a unique manner during the phase when cell division occurs, known as mitosis. Understanding this novel mechanism and identifying its function at this critical stage of cell division will provide insights into how cell control the partitioning of replicated genome and produce two identical daugther cells.Read moreRead less
Functional characterisation of CMAP, a novel centrosome- and midbody-associated protein. Cell division is a highly regulated process involving many components to produce two daughter cells which contain an equal amount of DNA. Thus incorrect localisation and modification of specific proteins that regulate this process cause cell division errors resulting in genomic instability. We have recently identified a novel protein called CMAP that is involved in the final stages of cell division, which in ....Functional characterisation of CMAP, a novel centrosome- and midbody-associated protein. Cell division is a highly regulated process involving many components to produce two daughter cells which contain an equal amount of DNA. Thus incorrect localisation and modification of specific proteins that regulate this process cause cell division errors resulting in genomic instability. We have recently identified a novel protein called CMAP that is involved in the final stages of cell division, which involves the cleavage of the cell membrane to produce two daughter cells. Here, we aim to characterise the mechanism(s) of CMAP function and to identify and characterise CMAP binding proteins to further understand the mechanisms involved in the final stages of cell division to maintain genomic stability.Read moreRead less

This project is one of the first systematic investigations into the development of the human capacity to consider future events. A variety of novel tasks will probe what children know about the future and how it relates to their ability to reason about past events. Comparisons between children and apes will further inform us about the nature of this crucial mental skill. The findings will provide valuable information for developing appropriate educational approaches and for our understanding of abnormalities. As international leaders in this field, we are in an ideal position to conduct this research, offer unique opportunities for postgraduate training, and to continue in Australia's outstanding tradition of excellence in basic research.Read moreRead less
The nature of self-recognition: novel approaches to vexing questions. Mirror self-recognition has often been interpreted as evidence for the presence of some form of self-concept/awareness. Children from age 2 onwards investigate their own bodies after seeing a novel mark on their heads in the mirror (surreptitiously placed in their hair by the experimenter). Younger children and most animals do not respond to their images in such a way (instead, for example, treating it as another individual). ....The nature of self-recognition: novel approaches to vexing questions. Mirror self-recognition has often been interpreted as evidence for the presence of some form of self-concept/awareness. Children from age 2 onwards investigate their own bodies after seeing a novel mark on their heads in the mirror (surreptitiously placed in their hair by the experimenter). Younger children and most animals do not respond to their images in such a way (instead, for example, treating it as another individual). The present experiments probe the nature of self-recognition using novel digital video technology rather than mirrors. This technology allows us to manipulate the contingency and appearance of the image. Five studies investigate the performance of 2 to 4-year-old children, autistic children, chimpanzees and dolphins to determine whether they recognize themselves and what underwrites their performance on the tasks. The innovative use of modern technology is expected to answer some of the most persistent questions in psychology.
