Extracting energy from air: mechanism of a bacterial hydrogenase. The atmosphere has recently been shown to be a key source of energy for diverse soil bacteria. Bacteria use complex enzymes, namely Huc-type hydrogenases, to harvest atmospheric hydrogen directly from air to support growth and survival. However, little is known about how Huc functions within and outside cells. By synergising expertise in microbiology, biochemistry, and chemistry, we will resolve the mechanism, assembly, and integr ....Extracting energy from air: mechanism of a bacterial hydrogenase. The atmosphere has recently been shown to be a key source of energy for diverse soil bacteria. Bacteria use complex enzymes, namely Huc-type hydrogenases, to harvest atmospheric hydrogen directly from air to support growth and survival. However, little is known about how Huc functions within and outside cells. By synergising expertise in microbiology, biochemistry, and chemistry, we will resolve the mechanism, assembly, and integration of Huc, including the basis of its remarkably high affinity and oxygen insensitivity compared to previously studied hydrogenases. This project will enable biotechnological applications, as the first study of an enzyme that extracts energy from air, and has broad ecological and biogeochemical implications.Read moreRead less
Decentralised assets trading, centralised clearing and systemic risk. This project aims to study the effect of regulating over-the-counter (OTC) financial markets on economic performance. The lack of transparency of OTC financial markets may have exacerbated the severity of the 2007-09 financial crisis. In response, regulators around the world decided to mandate centralised clearing of derivatives traded OTC, believing this would reduce system-wide risk. This project will study the regulatory ch ....Decentralised assets trading, centralised clearing and systemic risk. This project aims to study the effect of regulating over-the-counter (OTC) financial markets on economic performance. The lack of transparency of OTC financial markets may have exacerbated the severity of the 2007-09 financial crisis. In response, regulators around the world decided to mandate centralised clearing of derivatives traded OTC, believing this would reduce system-wide risk. This project will study the regulatory change’s effects on market participation, volumes of trade and prices, and the behavioural effect of shifting risk from market participants to clearinghouses. It expects to suggest remedial policies clearinghouses could implement to control market participants’ risk appetite. These can help enhance future productivity and reduce unemployment in Australia.Read moreRead less
Incomplete Information Models for Industrial Organisation. Mergers, acquisitions, and collusive conduct take place in imperfectly competitive environments where firms have incomplete information about others. Despite this, standard workhorse models for analyzing the associated competitive effects assume that firms have complete information and typically only accommodate imperfect competition on one side of the market. This project aims to remedy this deficiency by developing the economic theory ....Incomplete Information Models for Industrial Organisation. Mergers, acquisitions, and collusive conduct take place in imperfectly competitive environments where firms have incomplete information about others. Despite this, standard workhorse models for analyzing the associated competitive effects assume that firms have complete information and typically only accommodate imperfect competition on one side of the market. This project aims to remedy this deficiency by developing the economic theory and associated practical tools for the analysis of competitive effects in settings with incomplete information and market power on both sides. The project work will be presented at seminars and workshops around the globe to both academic audiences and to practitioners at competition authorities. Read moreRead less
The production, use and effect of social work research. This project aims to reform social work research to improve the quality and effectiveness of human services. The human services industry is vital to many people’s quality of life, but lacks innovation and struggles to demonstrate its effectiveness. Crucially for social work, research expands thinking about how to respond to social disadvantage. This project intends to examine the scope and quality of Australian social work research in child ....The production, use and effect of social work research. This project aims to reform social work research to improve the quality and effectiveness of human services. The human services industry is vital to many people’s quality of life, but lacks innovation and struggles to demonstrate its effectiveness. Crucially for social work, research expands thinking about how to respond to social disadvantage. This project intends to examine the scope and quality of Australian social work research in child protection, disability services, and aged care; assess the use of this research to the human services sector and its effect on generating innovation; and develop strategies to advance the production, uptake, and effect of social work research.Read moreRead less
Living on air: how do bacteria scavenge atmospheric trace gases? This project aims to determine the molecular and cellular basis of atmospheric trace gas oxidation by bacteria. Bacteria have a remarkable ability to adapt to resource limitation and environmental change by entering dormant states. Our research has shown they survive in this state by using atmospheric hydrogen and carbon monoxide as energy sources. This interdisciplinary project will determine how bacteria achieve this by elucidati ....Living on air: how do bacteria scavenge atmospheric trace gases? This project aims to determine the molecular and cellular basis of atmospheric trace gas oxidation by bacteria. Bacteria have a remarkable ability to adapt to resource limitation and environmental change by entering dormant states. Our research has shown they survive in this state by using atmospheric hydrogen and carbon monoxide as energy sources. This interdisciplinary project will determine how bacteria achieve this by elucidating the regulation, mechanism, and integration of the three uncharacterised enzymes that mediate this process. Outcomes and benefits include understanding of the processes that facilitate bacterial persistence, regulate atmospheric composition, and in turn support resilience of natural ecosystems.Read moreRead less
Wicked defaults: how to overcome the dark side of choice architecture. This project aims to investigate how defaults and product complexity might be used to exploit consumers in environments like private insurance where consumers are prone to making systematic errors. Defaults are used to nudge individuals into socially beneficial actions such as increasing their retirement savings and joining organ donor lists. However, in the hands of firms, defaults can also be used to exploit consumers by en ....Wicked defaults: how to overcome the dark side of choice architecture. This project aims to investigate how defaults and product complexity might be used to exploit consumers in environments like private insurance where consumers are prone to making systematic errors. Defaults are used to nudge individuals into socially beneficial actions such as increasing their retirement savings and joining organ donor lists. However, in the hands of firms, defaults can also be used to exploit consumers by encouraging choices that help the firm but disadvantage consumers. The project intends to study experimentally whether exploitation can be reduced via competition and reputation building systems based on consumer feedback.Read moreRead less
Testing an Integrative Model of Interpersonal Partner Aggression. The project aims to conduct: 1) a developmental test (i.e., from childhood to adulthood), and 2) a dyadic longitudinal test of an integrative model of intimate partner violence (IPV). The project is significant as it addresses 4 key IPV research limitations. These are the lack of: 1) focus on relationship dynamics; 2) longitudinal research on couples; 3) developmental tests of IPV; 4) research on same-sex couples. Expected outcome ....Testing an Integrative Model of Interpersonal Partner Aggression. The project aims to conduct: 1) a developmental test (i.e., from childhood to adulthood), and 2) a dyadic longitudinal test of an integrative model of intimate partner violence (IPV). The project is significant as it addresses 4 key IPV research limitations. These are the lack of: 1) focus on relationship dynamics; 2) longitudinal research on couples; 3) developmental tests of IPV; 4) research on same-sex couples. Expected outcomes include a comprehensive suite of assessments to effectively detect and support couples at risk of IPV and self-help resources to combat IPV. Benefits include the development of an integrative framework to identify couples most at risk of IPV and guide the development of interventions and policy to reduce IPV.Read moreRead less
Building trust and sustainability by promoting a moral frame to nature. The collective benefits of sustainable behaviour tend to be abstract and less obvious compared to the immediate benefits of self-interest. This project aims to examine an avenue through which to make these benefits more concrete and personal – by providing a moral frame to nature. The studies aim to explore how this may be achieved, the socio-ecological factors that might limit such attempts, and the downstream implications ....Building trust and sustainability by promoting a moral frame to nature. The collective benefits of sustainable behaviour tend to be abstract and less obvious compared to the immediate benefits of self-interest. This project aims to examine an avenue through which to make these benefits more concrete and personal – by providing a moral frame to nature. The studies aim to explore how this may be achieved, the socio-ecological factors that might limit such attempts, and the downstream implications for generalised trust and cooperation amongst human groups. We expect the findings will offer insight into an important avenue through which we can leverage human cooperation and trust and promote the value of the common good. Read moreRead less
