Valerie’s research focusses on coastal ecosystem conservation and restoration. She holds an AXA-UNESCO research fellowship on mangrove community forestry for resilient coastal livelihoods, endorsed as an action of the UN Ocean Decade. She co-leads a National Environmental Science Program (NESP) project on carbon abatement and biodiversity enhancements from controlling feral ungulates in wetlands in Australia and is developing a framework to measure verified biodiversity benefits in coastal wetland restoration projects in partnership with CSIRO. She recently led a NESP project on coastal wetland restoration opportunities in Australia for blue carbon and co-benefits for biodiversity, fisheries, water quality, and coastal protection and an Australian Research Council linkage project to identify social and ecological conditions that enable effective mangrove conservation over global and regional scales with partners at The Nature Conservancy and Healthy Land and Water. She has published research on the drivers of global mangrove losses and gains and coastal wetland restoration opportunities. She has co-authored international guidelines on mangrove restoration with Conservation International and incorporation of coastal wetlands into national greenhouse gas inventories with the Australian Government International Blue Carbon Partnerships. Valerie is an experienced ecologist and is a board member of the Society of Ecological Restoration Australasia and a representative of Australia’s Restoration Decade Alliance.
Sreekar’s research focuses on using ecological theory to inform conservation decision making. He is interested in a broad range of topics, including spatial conservation planning, evidence-based conservation policy, community assembly rules, extinction synergies, and land-use management. A big question that drives his research is how to address the twin crises of climate change and biodiversity loss. His current research is centred around studying the environmental risks associated with mining and mineral processing.
He serves as an Associate Editor for the Journal of Applied Ecology and has spent the past 15 years at universities across Australia, China, Czechia, India and Singapore. Sreekar is an avid birder and enjoys this aspect of his work both professionally and recreationally.
RESEARCH INTERESTS Fire Ecology, Ecological Genomics, Wildlife Ecology, Conservation Biology, Invasive Plants
My research group studies fire ecology and conservation biology. Currently, we are working on:
Managing interactions between changing fire regimes and invasive plants
Influence of changing fire regimes on plant-animal interactions
Restoration of native grassland
Biodiversity in agricultural landscapes
Platypus distribution & conservation
We have a special interest in plants and animals living in fire-prone areas because of the fascinating fact that these ecosystems are never static but continually re-shaped by cycles of fire and regeneration. While being grounded in fundamental biology and ecological theory, our research is always aimed at improving knowledge for biodiversity conservation. Our work has applications in fire management, biological invasion and threatened species conservation.
TECHNICAL APPROACHES: POPULATION GENETICS | SPATIAL LANDSCAPE GENETICS | DEMOGRAPHIC SIMULATION MODELLING | STATISTICAL MODELLING OF POPULATIONS & COMMUNITIES | BIOINFORMATICS | SPATIAL ANALYSIS IN R | We also know how to drop a hand-made 1 x 1 m polypipe quadrat on the ground and do good old-fashioned field work.

I'm a quantitative community ecologist with broad experience across terrestrial and marine systems, modern and geological time, local and global scales with both theoretical and practical focus. I'm driven by discovery, interested in myriad topics on how communities form and function, but particularly how we measure and make comparisons between communities.
Translating anomaly detection to ecology: In a world experiencing climate change, biodiversity loss and other human impacts, detecting anomalous ecological systems accurately and early potentially offers vast benefits to conservation and ecosystem management. Anomaly detection is a fast-moving area of research applied in fields as varied as banking fraud detection, cybersecurity and cancer diagnosis. These fields deal with data as complex and incomplete as ecology, but we haven't plumbed this expertise for benefits to ecology. This is the primary focus of my DECRA.
Grounding ecological novelty for practical use: Ecologists have been talking about novel systems for twenty years, and related topics (such as "no-analog systems") for even longer. Despite well-cited work on how "novel" can be a useful label for ecological restoration, there's a mismatch between management frameworks, which often use ad-hoc qualitative criteria, and quantitative novelty research, which has been mostly performed at global scales. Understanding how to measure novelty, how analytic choices affect measurements, and how to downscale our inferences to be practicable, has been a focus for me and my colleagues.
The linguistic evolution of programming languages: The use of scientific programming languages like R, Python and Julia are becoming not only popular, but mandatory skills for researchers. The utility of these languages has been improved by new versions and a plethora of community-created addon packages. This approximates features of natural language evolution, where lexicon changes over time. Understanding the speed and direction of how programming languages evolve can give us a unique insight into how humans learn and alter languages, and how we might ensure they remain understandable into the future. I am currently using GitHub as a vast repository of time-stamped programming “texts”, ripe for linguistic analysis.
Community ecology through the lens of functional traits: It doesn’t matter who you are, it matters what you do. That applies to organisms too. Despite decades of research into how physiology and life history strategy, often proxied through easy-to-measure “functional traits”, functional ecology is still more niche than it should be. Currently my colleagues and I are exploring how a functional lens alters ecological novelty, but I am always thinking about ecology in the light of how organisms live.
