The ability of cells to regulate gene expression is key for organism development, adaptation to new environments and evolutionary changes that shape the diversity of life on Earth. This project studies the RNA binding proteins called PUFs which are central for gene expression in diverse organisms. Using cutting-edge new generation systems biology approaches, this project will study how PUF proteins regulate genes to enable metabolic adaptation, differentiation of cell types and the evolution of new gene expression outputs in distinct biological species. The outcomes will include new insights into the regulation and evolution of posttranscriptional gene networks. Read moreRead less
Chemo-sensation in Ascaris infection. This project aims to show the role of chemo-sensation as an equally important target for worm control, and explore pathways to prevent infection. Parasitic worms cost global food/textile industry more than $100 billion dollars per year, and cause disease in more than 1 billion people and domesticated animals world-wide. This project will use a combination of imaging, systems biology, chemical biology and microfluidic methods to provide significant benefits, ....Chemo-sensation in Ascaris infection. This project aims to show the role of chemo-sensation as an equally important target for worm control, and explore pathways to prevent infection. Parasitic worms cost global food/textile industry more than $100 billion dollars per year, and cause disease in more than 1 billion people and domesticated animals world-wide. This project will use a combination of imaging, systems biology, chemical biology and microfluidic methods to provide significant benefits, such as exploring Ascaris chemo-sensation during larval migration, identify the key host queues and parasite genes regulating this process, and probe helminth chemosensation as a novel target for anti-parasitic treatments.Read moreRead less
Uncovering microRNA decay regulation in mammalian cells. MicroRNAs (miRNAs) constitute a novel mechanism used by cells to regulate gene expression, however, very little is known about the mechanisms affecting miRNA accumulation. Characterisation of the kinetics of miRNA turnover is of paramount importance to establish the reliability of miRNAs as novel biomarkers. This project aims to characterise miRNA stability in mammalian cells, investigate mechanisms of turnover and establish their importan ....Uncovering microRNA decay regulation in mammalian cells. MicroRNAs (miRNAs) constitute a novel mechanism used by cells to regulate gene expression, however, very little is known about the mechanisms affecting miRNA accumulation. Characterisation of the kinetics of miRNA turnover is of paramount importance to establish the reliability of miRNAs as novel biomarkers. This project aims to characterise miRNA stability in mammalian cells, investigate mechanisms of turnover and establish their importance on the regulatory function of miRNAs. Such information is critical in the future development of targeted therapeutics.Read moreRead less
Translating pharmacokinetic and pharmacodynamic data to better design new drugs for the treatment of Trypanosoma cruzi infection. New drugs to treat T. cruzi infection are urgently needed, however their design has been hampered by an incomplete understanding of complex host-parasite interactions, inadequate in vitro and in vivo tools to rigorously define activity during drug discovery, and a poor appreciation of concentration/effect relationships. This project aims to develop new and much needed ....Translating pharmacokinetic and pharmacodynamic data to better design new drugs for the treatment of Trypanosoma cruzi infection. New drugs to treat T. cruzi infection are urgently needed, however their design has been hampered by an incomplete understanding of complex host-parasite interactions, inadequate in vitro and in vivo tools to rigorously define activity during drug discovery, and a poor appreciation of concentration/effect relationships. This project aims to develop new and much needed in vitro methods to better define the kinetic and dynamic activity of new drug candidates, and will provide a rational basis for translating this information into lengthy animal models of T. cruzi infection. The outcome aims to be rationally designed drug candidates that are available in a shorter period of time and are suitable for further development.Read moreRead less

Summary
Targeting bacterial superbugs: novel approaches for optimisation of antibiotic combinations and resistance prevention. This project will elucidate the mechanistic basis to optimally combine available beta-lactam antibiotics to prevent resistance of gram-negative 'superbugs'. The interdisciplinary project will substantially contribute to solving the global crisis due to multidrug-resistant bacteria and inform the design of effective new antibiotics.
Targeting an impending global disaster: the mismatch between increasingly drug-resistant superbugs and development of new antibiotics. This project will develop much-needed novel antibiotics for treating infections caused by bacteria that are resistant to all current antibiotics. It will make a significant contribution to the global medical challenge of a shortage of new antibiotics.
Rational design of new drug candidates for the treatment of Trypanosoma cruzi infection. There is a serious shortage of safe and effective drugs to treat Chagas disease which is caused by a parasitic infection. This project aims to design and identify new drug candidates by defining the disposition profile within the body which is necessary to achieve a therapeutic effect.
Cellular and molecular networks controlling protective immunity. This research aims to understand how a handful of master-regulator genes act to program immune cells required for immune responses to microbes, vaccination and to prevent cancer. It will provide a fundamental advance in our understanding of immune cell development and impact strategies aimed at the prevention and treatment of pathogen infections.
Mathematical and statistical methods for modelling invivo pathogen dynamics. This project aims to develop mathematical models and Bayesian statistical methods that better capture how natural defence responses and drugs help control infection. When viruses (e.g. influenza) or parasites (e.g. malaria) invade the human body, they begin to replicate. To date, only simple mathematical models have been developed to capture these processes, and these models are not well formulated.

When viruses (e.g. influenza) or parasites (e.g. malaria) invade the human body, they begin to replicate. To date, only simple mathematical models have been developed to capture these processes, and these models are not well formulated. This project will improve biomathematics and biostatistical algorithms for pathogen dynamics and is ultimately expected to benefit public health and clinical research aimed at alleviating the effect of infectious diseases on human health.Read moreRead less

Summary
Mathematical and statistical modelling of antimalarial drug action. This project aims to develop a mathematical model to optimise global antimalarial treatment policy. Malaria-causing parasites are resistant to the most potent antimalarial drug available. If left unaddressed, a catastrophic rise in global malaria incidence and mortality could occur. Changes to global antimalarial treatment policy increasingly rely on mathematical models, but they do not encompass recent breakthroughs in antimala ....Mathematical and statistical modelling of antimalarial drug action. This project aims to develop a mathematical model to optimise global antimalarial treatment policy. Malaria-causing parasites are resistant to the most potent antimalarial drug available. If left unaddressed, a catastrophic rise in global malaria incidence and mortality could occur. Changes to global antimalarial treatment policy increasingly rely on mathematical models, but they do not encompass recent breakthroughs in antimalarial drug action and the immune response. This project’s model is expected to improve antimalarial drug dosing regimens and control the spread of antimalarial drug resistance.Read moreRead less
