Research Fellows

Dr Edith Arndt

Edith Arndt Edith is an alpine ecologist and research fellow at the University of Melbourne.  Her past research focused on investigating soil nitrogen pools and transformations in alpine ecosystems, as well as root nitrogen uptake, in relation to temperature and fire.  Working in the Victorian government in the areas of environmental monitoring, evaluation and outcome reporting, remote sensing, and data management have equipped her with an understanding of government processes and land management.  Her current work includes developing measures for assessing the health of the Australian biosecurity system and determining the level of confidence for the absence status of plant pests.


Dr Chris Baker

Chris is an applied mathematician with an interest in invasive species. He has worked across government and academia on a variety of topics. This includes researching models for managing antimicrobial resistance, invasive species management and COVID preparedness. He has a particular interest in the overlap between ecology and epidemiology and how decision science can be better used to inform epidemic management.


Dr John Baumgartner

John is a computational ecologist with a research background exploring the potential impacts of climate change on biodiversity. His research involves developing software tools and applying quantitative methods to support conservation and biosecurity decision-making. John has a keen interest in data analysis, and enjoys nice maps and code golf.


Nathaniel Bloomfield

Nathaniel holds a Bachelor of Philosophy from the Australian National University, majoring in theoretical chemistry. He has two and a half years experience working in the plant health monitoring team and completed the graduate program at the Australian Bureau of Agricultural and Resource Economics and Sciences (ABARES).


Dr Richard Bradhurst

Dr Richard BradhurstRichard Bradhurst is interested in the fusion of multiple modelling approaches (equation-based, agent-based and cellular automata), to produce epidemiologically authentic and computationally tractable simulations of the spatiotemporal spread and control of emergency animal diseases. He collaborates with the Australian Department of Agriculture, Water Resources and the Environment, the New Zealand Ministry of Primary Industries, ANU, CSIRO and the EuFMD Commission within the Food and Agriculture Organisation of the United Nations. Previously, he spent over 20 years as a software/firmware engineer on large mission/life critical projects in both Australia and North America. Projects included SCADA, a submarine combat system, civilian and military automated air traffic control systems, and tactical communication systems for the Canadian, British and United States military.


Dr James Camac

James is a quantitative ecologist. His research has focused on examining how climate change and fire influence Australian alpine vegetation dynamics and how plant traits influence growth, mortality and fire recovery. James is currently working on: 1) developing statistical tools for quantifying confidence in pest freedom; and 2) developing risk maps of pest establishment.


Dr Aaron Dodd

Dr Aaron DoddAaron is an ecologist applying concepts drawn from ecology, epidemiology, risk analysis, decision theory and economics to inform biosecurity service delivery.  Aaron is currently working on potential approaches for estimating the value of complex biosecurity interventions with a view to informing large-scale resource allocation decisions.


Associate Professor Jane Elith

Dr Jane ElithJane is a Senior Lecturer in the School of BioSciences at the University of Melbourne. She specialises in species distribution models, statistical models that describe relationships between the occurrence or abundance of species and the environment. Jane has made outstanding original academic contributions to species modelling by authoring highly cited guides to methods, helping develop and extend methods appropriate for typical data types, and testing methods and exploring their uncertainties. Her current projects include conservation and invasive species applications, and explorations of model tuning, evaluation and uncertainties.


Dr Anca Hanea

Anca HaneaAnca is an applied mathematician and a research fellow at the University of Melbourne. Her research interests and experience lie in high dimensional dependence modelling, risk analysis, decision theory, probabilistic graphical models, and structured expert judgement. Her current research is focused on structured expert judgement elicitation and aggregation methods for Bernoulli distributed random variables.


Dr Sean Haythorne

Sean is a multidisciplinary researcher and educator with a background in computer science and ecological modelling. As well as having experience as an IT teaching academic, he has been collaboratively developing computational solutions for biological science for several years. In his role as a research software engineer at CEBRA he is helping develop cloud-based software tools for the biosecurity research and operational science community.


Martina Hoffmann

Martina HoffmannMartina Hoffmann is a statistical research assistant, communications officer and tutor at the University of Melbourne. She holds a double degree in actuarial studies and science (mathematics and statistics). After completing the graduate program at the Australian Bureau of Agricultural and Resource Economics and Sciences (ABARES), Martina worked in Border Compliance at the then Department of Agriculture, Fisheries and Forestry. As well as conducting statistical research, she also manages the communications at CEBRA. She is interested in science communication and data visualisation.


Christine Li

Christine is an environmental economist and holds an honours degree in economics from the University of Melbourne. She has experience in policy and analysis from working at Deloitte Access Economics, the Department of Treasury and Finance and Department of Environment, Land, Water and Planning. Her current work involves creating tools for biosecurity decision-making and estimating global crop yield damage functions for climate impact modelling.


Dr Libby Rumpff

Libby is a leader in the field of structured decision making for natural resource management and conservation. Her work focuses on applying tools and techniques to help resolve the uncertainty that hampers decision-making. She brings together skills in plant ecology, decision theory, risk assessment, expert elicitation, facilitation, and model development.


Dr Raphael Trouvé

Raphael is a forest modeller and research fellow at the University of Melbourne. His past research focussed on developing methods to quantify the interactive effect of management and climate change on forest dynamics. His current work includes developing robust forest dynamic models to forecast stand trajectories under future conditions, exploring alternative statistical inference frameworks for biosecurity border inspection, and using statistical and machine learning methods to gather intelligence about the biosecurity risk associated with different plant import pathways.
