Summary
Presenilin, a protein involved in Alzheimer’s disease (AD), may regulate copper and zinc levels. Copper and zinc are essential nutrients however a deficiency or excess can cause disease. Promising metal-altering AD drugs, are in various stages of clinical trial. I aim to characterize the interaction of Presenilin and metals using both mouse and cultured human cell models that are deficient in Presenilin. Understanding this interaction should lead to better drug design and treatment of AD.

Summary
Programmed cell death termed apoptosis is a process our bodies use to remove cells that are a threat to our health, e.g. cancer cells. The proteins that regulate cell death are attractive targets for therapeutics that have become resistant to this defence mechanism. This study will reveal how proteins from the Bcl-2 family regulate cell death at the molecular level. Understanding this process will inform the development of drugs aimed at regulating cell death in cancer and other diseases.

Summary
Recently, we and others have demonstrated that part of the MLKL protein is able to kill cells. This process is known to cause a number of pathologies, including those arising from stroke. Blocking this type of cell death has thus emerged as an attractive therapeutic strategy. However, precisely how MLKL kills cells remains unclear and controversial. In this project, we will resolve these controversies with the goal of an increased fundamental understanding to aid drug discovery.
The Effective Treatment of Hot Dip Galvanizing Effluent Streams. Hot Dip galvanizing effluent represents a significant environmental hazard. This wastewater is currently trucked offsite and treated by contractors to precipitate a heavy metal sludge that is disposed of through landfill. Industrial Galvanisers, as the largest hot dip galvanizing company within Australia, are keen to eliminate this hazard. We will consider the use of an innovative membrane based process for this purpose; to recover ....The Effective Treatment of Hot Dip Galvanizing Effluent Streams. Hot Dip galvanizing effluent represents a significant environmental hazard. This wastewater is currently trucked offsite and treated by contractors to precipitate a heavy metal sludge that is disposed of through landfill. Industrial Galvanisers, as the largest hot dip galvanizing company within Australia, are keen to eliminate this hazard. We will consider the use of an innovative membrane based process for this purpose; to recover valuable zinc and iron compounds from the effluent and allow the water to be re-utilised. If successful, this project will lead to a pilot plant wastewater treatment plant being constructed at an Industrial Galvanizers site.Read moreRead less
The Treatment Of Galvanizing Wastewater: Delivering An Environmentally And Economically Sustainable Approach. This project will investigate a process to treat wastewater from industrial galvanizing sites around Australia. When implemented, the process will substantially reduce the consumption of acid and fresh water at these sites. Further, the process will recover the zinc content of the wastewater in a saleable form and can also generate ferric chloride for sale as a water treatment chemical. ....The Treatment Of Galvanizing Wastewater: Delivering An Environmentally And Economically Sustainable Approach.

When implemented, the process will substantially reduce the consumption of acid and fresh water at these sites. Further, the process will recover the zinc content of the wastewater in a saleable form and can also generate ferric chloride for sale as a water treatment chemical. The quantity of heavy metals disposed to landfill will also be dramatically reduced. Scientific knowledge of multicomponent liquid-liquid equilibria will be of value to a wider range of solvent extraction processes including zinc and copper metal refining.Read moreRead less

This will be done through a study of the columns in operation at GlaxoSmithKline's operation at Port Fairy alkaloids plant. In addition a detailed study of the influence of impurities on the coalescence rate of liquid dispersions will be undertaken as this is an important rate limiting step in column performance. The benefit to GlaxoSmithKline will be a more efficient and optimised plant. The benefit to Australian processing industries is a reliable method of relating small scale trials to full size column performance which is a significent problem in the minerals industry at present.Read moreRead less

Summary
The human nervous system and organs are reliant on precisely controlled transmission of electrical currents through sodium and potassium channels. Their core functions are compromised when currents fail to switch on and off normally. Faulty potassium channels are implicated in diabetes, epilepsy and heart failure. This project re-examines the mechanisms controlling potassium channels, with a view to scientific and therapeutic discrimination between the different classes present in human cells.

Skeletal muscles represent the largest organ in the body of vertebrates and are responsible for major functions including maintaining posture and locomotion. Skeletal muscles are also a major source of heat production. The project focuses on temperature-induced effects on the ability of the skeletal muscle to contract in warm blooded animals, including marsupials, and on the complex roles played by a cellular structure unique to the muscle fibre, the tubular system, with respect to regulation of muscle function at physiological temperatures. The project will test hypotheses that will have far-reaching implications for muscle physiology, cell biology and evolutionary biology.Read moreRead less
Oxidative stress-induced alterations of the host erythrocyte by the malaria parasite. The malaria parasite spends part of its lifecycle inside the red blood cells of its host. During this time, the parasite modifies many of the features of the red blood cell and subjects it to high levels of oxidative stress.

During this time, the parasite modifies many of the features of the red blood cell and subjects it to high levels of oxidative stress. We will use and develop a variety of fluorescence and microscopic techniques to understand the molecular basis of the alterations in the organization of membrane proteins in malaria parasite-infected red blood cells.
