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

This project aims to develop new curatorial models to enable Australian art galleries to respond effectively to changes in the medium of photography wrought by digital technologies. By conducting the first comprehensive analysis of nearly five decades of Australian photography curating and comparing it to curatorial approaches in related institutions locally and internationally, the project seeks to: identify the crucial role of photography exhibitions in the shaping of Australian visual culture; and develop opportunities for curators to better engage with the current proliferation of images, including new forms and practices of photography enabled by the Internet.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
Economic efficiency and the provision of incentives for information acquisition and disclosure: a mechanism design approach. By uncovering what determines information acquisition, highlighting what allows experts and insiders to manipulate market outcomes, and studying the efficiency gains obtainable with the use of a variety of incentives schemes, this research will provide valuable insights for public policy concerning information diffusion and market transparency.
Tertiary admissions: towards a healthier university system. The project aims to identify the demand for university places, quantify the gains from the Australian semi-centralised admissions system and propose measures to increase these gains. The effectiveness of any tertiary education system depends critically on the quality of the match between students and courses, with mismatches resulting in millions of dollars of wasted public resources and life dissatisfaction of graduates in occupations ....Tertiary admissions: towards a healthier university system. The project aims to identify the demand for university places, quantify the gains from the Australian semi-centralised admissions system and propose measures to increase these gains. The effectiveness of any tertiary education system depends critically on the quality of the match between students and courses, with mismatches resulting in millions of dollars of wasted public resources and life dissatisfaction of graduates in occupations misaligned with their interests. Using an Australian tertiary admissions dataset containing both student preferences and rankings of students by courses, the project aims to empirically assess the trade-off between the efficiency of a match, an equitable welfare distribution and equal access to higher education. It then plans to propose the best system to balance these objectives.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
