The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

Target Of Rapamycin control of nutrient uptake. This project aims to study nutrient uptake in eukaryotes. It is expected to generate new knowledge of critical and conserved features of environmental and Target Of Rapamycin (TOR)-mediated control of nutrient uptake, specifically endocytosis, building on novel preliminary data that identifies novel TOR control points. The expected outcomes include new insights into mechanisms controlling nutrient uptake and fostering institutional collaboration. T ....Target Of Rapamycin control of nutrient uptake. This project aims to study nutrient uptake in eukaryotes. It is expected to generate new knowledge of critical and conserved features of environmental and Target Of Rapamycin (TOR)-mediated control of nutrient uptake, specifically endocytosis, building on novel preliminary data that identifies novel TOR control points. The expected outcomes include new insights into mechanisms controlling nutrient uptake and fostering institutional collaboration. This knowledge is highly relevant to any industry or research project utilising living organisms, as nutrient availability supports survival, cell growth and proliferation.Read moreRead less
The control of elongation factor 2 and its role in the regulation of protein synthesis. Protein synthesis is a key process in living cells. The main stage, elongation, is regulated through phosphorylation of elongation factor eEF2 in response to hormones, amino acids and cellular energy status, via changes in the activity of eEF2 kinase. We will study how these conditions control eEF2 kinase by studying its phosphorylation and identifying new kinases that regulate it. We will explore the role of ....The control of elongation factor 2 and its role in the regulation of protein synthesis. Protein synthesis is a key process in living cells. The main stage, elongation, is regulated through phosphorylation of elongation factor eEF2 in response to hormones, amino acids and cellular energy status, via changes in the activity of eEF2 kinase. We will study how these conditions control eEF2 kinase by studying its phosphorylation and identifying new kinases that regulate it. We will explore the role of eEF2 in controlling protein synthesis, seek new substrates for eEF2 kinase and initiate work to elucidate the structure of this unusual enzyme. This will enhance, in a range of ways, fundamental understanding of cell physiology.Read moreRead less
Gene Discovery and Functional Analysis of Copper Homeostasis Genes in Drosophila. Copper is a vital nutrient required for the formation and maintenance of bones, blood vessels and the central nervous system, but copper is also potentially toxic when in excess. Homeostatic mechanisms are needed to maintain safe levels of copper in the body and disruptions to these mechanisms are associated with disorders such as Alzheimer's disease, heart disease and osteoporosis. We are investigating the regulat ....Gene Discovery and Functional Analysis of Copper Homeostasis Genes in Drosophila. Copper is a vital nutrient required for the formation and maintenance of bones, blood vessels and the central nervous system, but copper is also potentially toxic when in excess. Homeostatic mechanisms are needed to maintain safe levels of copper in the body and disruptions to these mechanisms are associated with disorders such as Alzheimer's disease, heart disease and osteoporosis. We are investigating the regulation of a key copper pump, the Menkes protein, which helps control copper levels in the body and we are using the genetic advantages of the fruit fly Drosophila to discover new genes that regulate Menkes activity and therefore copper levels. These studies could lead to novel therapies for a range of copper-related disorders.Read moreRead less
