Analysing the protective role of platelets during malaria infection. Platelets protect the host during malarial infection. This project aims to study how platelets kill the malaria parasite by investigating the role of host molecules and their potential as novel antimalarial agents. The role of platelets in the pathogenesis of cerebral malaria syndrome will also be investigated.
Integrating electrophysiology and molecular biology to understand the role of cell membranes in bacterial responses to chill and osmotic stress. Modern food manufacture is driven by competing demands: consumers prefer foods that are 'natural', i.e. having received minimal processing and containing less preservatives, and last, but are safe. Thus, a challenge is to find minimal sets of treatments and preservatives that limit microbial growth.

Modern food manufacture is driven by competing demands: consumers prefer foods that are 'natural', i.e. having received minimal processing and containing less preservatives, and last, but are safe. Thus, a challenge is to find minimal sets of treatments and preservatives that limit microbial growth.
Current methods to for determining limits to microbial growth are time and consuming and empirical. We will assess the potential of a new method (MIFE) to rapidly measure limits of bacterial growth under combinations of treatments. At the same time we will study how cells, and in particular how the cell membrane, responds to these stresses to provide insights for the development of new, minimal - yet safe - food preservation technologies.

Quantifying the impacts of environmental stress on marine microorganisms. Microorganisms underpin marine ecosystem health, yet there is limited understanding of how they will respond to different environmental pressures. This project will resolve this critical knowledge gap by developing a unique molecular platform for deriving quantitative stress thresholds for microbial communities inhabiting key reef habitats (seawater, sediments, invertebrates). Quantifying how reef microorganisms respond to ....Quantifying the impacts of environmental stress on marine microorganisms. Microorganisms underpin marine ecosystem health, yet there is limited understanding of how they will respond to different environmental pressures. This project will resolve this critical knowledge gap by developing a unique molecular platform for deriving quantitative stress thresholds for microbial communities inhabiting key reef habitats (seawater, sediments, invertebrates). Quantifying how reef microorganisms respond to a broad suite of environmental perturbations (temperature, nutrients, contaminants), will generate stress-response data that can be incorporated alongside eukaryotic data in environmental assessments, greatly improving the ecological relevance and reliability of risk and vulnerability assessments.Read moreRead less
Climate-driven windblown dust and flood runoff can increase marine diseases by fungal pathogens. Determination of the role of fungal pathogens in marine disease outbreaks, and their linkages to climate-driven dust and flood events, have important applications for coastal fisheries and the Great Barrier Reef. This project will develop molecular tools and plankton recorder protocols to detect fungal outbreaks and assess ecosystem resilience.
Synthetic phenazines for enhanced biogas production from renewable and non-renewable resources. Methane (biogas) has a large role to play in meeting the energy needs of the human race globally whilst reducing greenhouse gas emissions. Microbial communities are responsible for biogas production from non-renewable (coal) and renewable (food waste) resources. This project seeks to: increase biogas yields by redirecting electron flow towards biogas producing microbes using electrochemically active p ....Synthetic phenazines for enhanced biogas production from renewable and non-renewable resources. Methane (biogas) has a large role to play in meeting the energy needs of the human race globally whilst reducing greenhouse gas emissions. Microbial communities are responsible for biogas production from non-renewable (coal) and renewable (food waste) resources. This project seeks to: increase biogas yields by redirecting electron flow towards biogas producing microbes using electrochemically active phenazines; understand the molecular mechanism by which phenazines increase biogas yields; and, assess the environmental consequence of phenazine application to coal seam gas production and anaerobic digestion of food waste. Phenazines are likely to emerge as a safe and cost-effective technology for improved biogas generation.Read moreRead less
