DARE 2023 Symposium Program

Data. Domains. Decisions.

10.00am | Welcome & Acknowledgement of Country

Willem VervoortWelcome: DARE Director, Professor Willem Vervoort (University of Sydney)

Willem has a PhD in field hydrology from the University of Georgia in the US and Agricultural Engineering undergraduate degree from Wageningen University. He is the leading hydrologist at The University of Sydney and an expert in quantitative Hydrology and Catchment Management and simulation modelling. His main research focus is on sustainable water management to balance climate and human impacts. He has a specific interest in agricultural management and impacts.

Willem combines remote sensing, field data and simulation modelling to develop quantitative tools scaling from the field to the continent. Current projects include Bayesian model optimisation, multi-objective model optimisation, understanding model uncertainty in relation to observed water quality and quantity, and the use of satellite data to improve model structures and predictions. Recent work developed soil moisture predictions for Australia and water accounting tools from the field to the landscape.

Fabian LealAcknowledgement of Country: DARE PhD Candidate, Fabian Leal (University of Western Australia)

Fabian is a DARE PhD student at the University of Western Australia. His current focus is on developing machine learning methods and statistical approaches that are capable of capturing uncertainty and ambiguity in data and models to improve decision making in the mining sector.

Fabian completed a Masters degree in Operations Research at the University of Chile, where his research consisted of applying mathematical programming to spatial conservation planning (SCP), a branch of ecology traditionally focused on strategically selecting the best areas for biodiversity conservation in a territory that, in recent years, has started to also take into consideration ecosystem services. Fabian formulated the first mixed integer programming (MIP) model capable of incorporating these additional variables, and applied it to the Daly River, in Australia, besting state-of-the-art heuristic Marxan with Zones’ results.

1.05pm | Keynote: ``Mind your Ps and Qs when analysing data`` (Professor David Warton)

David Warton

Professor David Warton (University of New South Wales)

When deciding how to analyse data, two key things we should always keep front of mind are the Properties of the data and the Question we are trying to answer – that is, we should mind our Ps and Qs. We will discuss some key data properties which, when not accounted for, can lead to substantial artefacts in analyses. We will also see the importance of the research question by looking at an example dataset and seeing that it could be analysed many different ways depending on the research question. Then we shall discuss a few projects where my research group is proposing new approaches in biodiversity research so that we can better mind our Ps and Qs: when monitoring the effects of ecological restoration efforts; automatically detecting and classifying wildlife from underwater videos and camera traps; and mapping species as a function of their environment in a changing climate.

David Warton is a Highly Cited Researcher at the interface between data science and ecology. At the University of Sydney, he completed an Honours project in plant ecology and a coursework Masters degree in statistics, before doing a PhD at the interface between the two at Macquarie University.

Since 2003 David has had an academic appointment at UNSW, where he leads the Eco-Stats group and has attracted over $4M in competitive research project funding. His cross-disciplinary research involves evaluating the methods for data analysis currently used in ecology, and where necessary, developing new methodologies to assist ecologists answer key research questions, with a special focus on multivariate techniques that can be used to understand ecological communities, and point process models that can be used in species distribution modelling. David is also the founding director of Stats Central, the UNSW statistical consulting and collaboration unit.

1.50pm | Dr Andrew McPherson from Geoscience Australia

Dr Andrew McPherson (Geoscience Australia)

Andrew is a senior geoscientist at Geoscience Australia, with 18 years experience across natural hazard and risk assessment, pre-competitive mineral exploration, environmental geoscience and hydrogeology. He has undergraduate qualifications from the University of Canberra in ecology and soil science, with an Honours degree in regolith geology. His PhD in Earth Sciences from the Australian National University focused on assessing sources and stores of salt in the landscape with applications to salinity management. He also has a Certificate IV in Asset Management (GIS Practices) from the Canberra Institute of Technology, and has recently completed a Graduate Certificate in Data Science at RMIT.

In collaboration with many colleagues, Andrew’s recent work has focused on using geophysical techniques (specifically airborne electromagnetics) to provide insights into geological variability within the recharge beds of the Great Artesian Basin in Queensland. Similar techniques are now being employed in the Upper Darling River floodplain region of western NSW, as part of the Australian Government’s Exploring for the Future program.

Clara’s research focuses on Bayesian modelling and computational aspects. In particular, she is interested in Bayesian clustering through mixture models, and the study of properties of prior distributions for clustering problems, and in dependence models such as copula models, when the interest lies on functional of the dependence. Part of her research is focused on computational algorithms to efficiently estimate Bayesian models, such as MCMC, ABC and variational Bayes. She has developed extensive applied collaborations, including modelling animal behaviours, association studies in genomics, portfolio optimization models in finance, long memory processes, machine learning for cybersecurity, modelling air pollution and its effect on vegetation and human health, modelling preferences.
