The most recent data fellows

Understanding the healthcare journey of high-cost patients

Robin Stevenson — Department of Health 

Robin’s project will bring together data from the Medical Benefits Scheme, the Pharmaceutical Benefits Scheme and hospital admissions. Diagnostic and treatment information will be used to find associations between the codes that doctors, pharmacists and other medical professionals assign to this data. This will then be used to understand the healthcare journeys of high-cost patients and to support evidence-based policy development.  

Robin is a data scientist and physicist and works at the Department of Health. Robin has a Bachelor of Philosophy (Honours) in physics and a PhD in physics.

Modelling household and family income from tax returns

Sam Bye — Australian Bureau of Statistics

It is known that income is most often shared at a household/family level. However, at the moment administrative income data is only available at the individual level. Sam will use the (de-identified) information collected on tax returns to model household and family income. This information can then be used to make policy decisions such as where to spend public money in areas such as health, education and social welfare. 

Sam is an Analyst at the Australian Bureau of Statistics. He has also worked in international banks and holds a Bachelor of Commerce and a Graduate Diploma in Applied Finance and Investment. 

Encouraging the productivity of Australian exporters

Shea Houlihan — Department of Prime Minister and Cabinet

Shea will encourage the productivity and competitiveness of Australian exporters by:

  • identifying a sub-set of low-performing businesses and
  • designing a behavioural intervention to help improve their performance.

The project will identify businesses that are most likely to respond to behavioural intervention, and aims to integrate behavioural science and machine learning to understand exporter behaviour.
 
Shea is a statistician at the Department of Prime Minister and Cabinet, in the Behavioural Economics Team of the Australian Government – BETA for short. Shea has also worked for the government in the UK, is a trained economist and has a PhD in policy evaluation.

Applying machine learning to intelligently impute missing values

Marcus Suresh — Department  of Industry

Datasets with missing values is a common and often unavoidable problem which can bias research. Marcus will develop an application to alleviate this bias by using machine learning to intelligently estimate missing values and substitute them into datasets used to forecast the trajectories of Australian firms through the economy.

Marcus is currently an economist at the Department of Industry and Innovation and Science, and has previously worked at the Commonwealth Treasury, Prime Minister and Cabinet and at the ANZ Bank. Marcus has a Bachelor of Economics (Honours), a Bachelor of Commerce (Accounting) and a Master of Public Policy (Economic Policy).

Using supervised machine learning to assign national Major Vegetation Groups to data

Jeremy Groves — Department of Environment and Energy

The way that the states and territories collect and supply native vegetation data, to the commonwealth, differs from state to state. This project will use supervised machine learning to assign national Major Vegetation Groups (MVGs) so there will not be the need for the states and territories to standardise their data. This project uses the NSW database, to keep the scope limited to start with, but model will be used on all state and territory data. This would mean that the states and territories won’t have to spend time standardising their data to the national system as consistency will be automated. The data is used for national and international legislation and vegetation maps.

Jeremy works in Environmental Resource and Information Network (ERIN) at the Department of the Environment and Energy. He has also worked in universities and the mining sector. He has an Associate Diploma in Geoscience, a Bachelor of Science (Environmental Science) and a PhD and Post-Doctoral research in freshwater ecology.

Past data fellows

Checking financial condition reports

Todd Campbell — Australian Prudential Regulation Authority

Todd looked at how to use text analytics to help identify insights and risks in prudential supervisory reviews of insurance companies’ financial condition reports. He also looked at identifying efficiencies and compiled an overview of the industry to assist supervisors.

These documents are currently reviewed manually to identify issues and feed into other risk assessments. Specialist teams also review the documents to help supervisors, and more systematic analysis could assist this process.

Todd is responsible for delivering an Innovation Centre Lab for the Australian Prudential Regulation Authority. 

The goal of the lab is to test modern analytics approaches that could provide new insights and support decisions relating to the authority’s prudential supervision role.

Automating land-use delineation

Rakhesh Devadas — Australian Bureau of Agricultural and Resource Economics and Sciences (Department of Agriculture and Water Resources)

Rakhesh developed techniques to automate the way agricultural land uses are mapped at a national scale.

His project improved methods for building the Land Use of Australia data series for understanding current and long-term changes in Australian land use. 

He did this by developing advanced geospatial data-analysis and modelling techniques. These techniques combine satellite-derived information and various national datasets.

Rakhesh has post-graduate qualifications in agricultural economics and a doctorate in spatial data applications.

His 16 years’ of professional experience include implementing operational projects for the NSW and Queensland state governments and research projects involving satellite time-series data at RMIT University in Melbourne and University of Technology Sydney.

Analysing government buying patterns

Patrick Drake-Brockman — Digital Transformation Agency

Patrick’s project provided data about the way government agencies buy products and services and the sellers they buy from.

He used longitudinal network analysis to look at datasets held by AusTender, the website where many contract details are posted. This analysis showed the effects policy changes have on forming networks between government agencies and sellers.

Patrick is a senior adviser in the Digital Transformation Agency’s investment office, providing advice to the government on ICT procurement proposals.

He’s spent 19 years in the Australian Government in roles including ministerial ICT support, critical infrastructure policy and national security information sharing policy.

Detecting non-compliance in regulatory schemes

Gabriella Duddy — Clean Energy Regulator

Gabriella used machine learning to help the Clean Energy Regulator (CER) detect non-compliance in its regulatory schemes.

She developed a process for the Small-Scale Renewable Energy Scheme to help the CER to use its resources more efficiently and strengthen the integrity of Australia’s Renewable Energy Target.

Gabriella has worked across the CER’s intelligence and analytics functions, helping to develop the agency’s approach to increasing data capability.

She’s in her final semester of a Master of Energy Change at the Australian National University in Canberra.

Targeting biosecurity risks at airports
