Dr Paul Carnell

PhD, University of Melbourne, AUS, 2010-2015
Research Assistant, Keough Lab, University of Melbourne, AUS, 2008-2010
BSc (Hons) Marine Biology and Ecology, University of Melbourne, AUS 2004-2008

Paul’s research career has a focus on environmental science that sits at the interface between high-quality research and science-based management of ecosystems. From further developing the science to offset carbon emissions through wetland restoration and protection, to the management of resilient coastal ecosystems. Paul has developed strong skills in experimental design and data analysis that underpins all of his work. Paul also has a strong background in fieldwork on marine and freshwater ecosystems, including seagrass, mangroves, saltmarsh, kelp forests and inland wetlands. It is in these coastal and inland wetland habitats, that Paul has been leading carbon stock assessments in the Blue Carbon Lab over the last couple of years. Through these projects Paul has developed strong relationships with Parks Victoria, Catchment Management Authorities in Victoria and New South Wales, Greenfleet and The Nature Conservancy.

Dr Stacey Trevathan-Tackett
Postdoctoral Fellow

PhD, University of Technology Sydney, AUS, 2012-2016
MSc Biology, University of North Florida, USA, 2009-2011
BSc Marine Science and Biology, Coastal Carolina University, USA, 2003-2007

Stacey’s research interests are in the fields of coastal biogeochemistry and microbial ecology. She currently working on projects to better understand the significance and intricacies of microbial transformation of carbon into greenhouse gases (CO2, CH4) within blue carbon habitats. We aim to identify the factors or processes that limit carbon remineralisation (back into greenhouse gases) and maximise the biosequestration of carbon in seagrass, mangrove and saltmarsh ecosystems. Stacey is also involved in seagrass wasting disease research. The protistLabyrinthula has been found to cause disease and occasional die-backs of seagrass species, however, we know nearly nothing about the distribution and function of Labyrinthula or the host-microbe relationship in Australia.

Carolyn Ewers
PhD candidate

PhD, Deakin University, AUS, 2014-current
MSc Biology, California Polytechnic State University, USA 2009-2013
Internship, Virginia Institute of Marine Science, USA 2007
BSc Marine Biology and Fisheries, California Polytechnic State University, USA 2006-2008

Carolyn’s research interests are in the fields of marine plant and animal ecology, including the effects of climate change on seagrass physiology and the relationships between seagrass and benthic invertebrates. She is currently working on her PhD thesis focused on understanding the dynamics of carbon sequestration in saltmarsh, mangrove and seagrass habitats (‘blue carbon’). Specifically, Carolyn is interested in 1) identifying and modelling factors driving differences in carbon stocks on local and regional scales, 2) investigating how land use changes (i.e., loss of intertidal wetlands due to reclamation) impact existing carbon stocks, sequestration, and greenhouse gas emissions, and 3) assessing opportunities for blue carbon ecosystem restoration along Australia’s southeast coastline.

Jeff Kelleway
PhD Candidate

PhD, University of Technology Sydney, AUS, 2013-current
Research Scientist, NSW DPI (Fisheries) and NSW OEH, 2005-2009
BSc (Hons) Environmental Science, University of New South Wales, 2011-2004


Jeff has over 10 years of experience as a wetland scientist. He has worked on projects investigating the impacts of physical disturbance on complex, fragile and largely understudied intertidal wetlands, as well as mapping and monitoring coastal wetlands and iconic wetlands of the Murray-Darling Basin (NSW). He has also undertaken stints as an ecologist in the northern Canadian wilderness and the private sector in Australia. Jeff is currently completing his PhD investigating the carbon sequestration potential, or ‘blue carbon’, of saltmarshes and mangroves. Jeff’s research aims to improve understanding of the quantity and character carbon stocks in coastal wetlands and their response to environmental change. This includes assessing the importance of geomorphic setting to carbon stocks, as well as identifying contributions of autochthonous (resulting from primary production within the saltmarsh) and allochthonous (imported from adjacent ecosystems or elsewhere in the catchment) sources to carbon stocks. Jeff’s recently published research also highlights large carbon increases associated with encroachment of saltmarshes by mangroves under rising sea level.

PhD, University of Melbourne, AUS, 2014-current
MSc Environmental Studies, University of Pennsylvania, USA, 2010 – 2012
BA Biology, University of Pennsylvania, USA, 2007 – 2012

Saras’ research interests include marine and freshwater aquatic ecology. Saras became interested in working on wetland systems after working for USAID on a wetland rehabilitation initiative for water-stressed Gaza Strip. Her PhD thesis (supervised by Peter Vesk at UMelb, Jane Catford at Univ. of Southhampton and Peter Macreadie) involves looking at the role of vegetation community composition and plant functional traits on carbon sequestration in freshwater wetlands, and how these relationships inform restoration. Her research aims to improve our understanding of the dynamics of carbon sequestration may contribute to better conservation of inland freshwater resources in Victoria.

Alex Thomson
PhD Candidate

PhD, University of Technology Sydney, AUS, 2013-current
BSc (Hons) Environmental Science, University of Technology Sydney, AUS, 2010-2012

Alex’s research interests lie in the areas of coastal and estuarine biogeochemistry and marine ecology, with particular interests in seagrass environments. She has worked to projects aimed to investigate the dispersal potential and establishment success of Zostera nigricaulis asexual vegetative propagules. Currently, Alex’s PhD research involves observing and experimenting with coastal blue carbon cycling in seagrasses, including the biogeochemical and microbial drivers of blue carbon and the effects of bioturbation by marine macrofauna on carbon stocks and fluxes. In addition to research, Alex has also been involved in teaching undergraduate courses as well as science outreach programs that aim to promote science and marine and environmental research to a range of school-aged children (primary and high-school), as well as in more public forums.

Quinn Ollivier
PhD Candidate

PhD Candidate, Deakin University Melbourne, AUS, 2016-current
BSc (Hons, First Class) Environmental Sciences, University of Technology Sydney, AUS, 2015 – 2016
BSc Marine Biology (Dean’s Merit Award 2015), University of Technology Sydney, AUS, 2012 – 2015

Quinn’s research interests lie within the field of whole ecosystem ecology, nutrient impacts on food web community structure and biogeochemical cycling, specifically, carbon sequestration in seagrass, saltmarsh and mangrove ecosystems (blue carbon ecosystems). He is currently working on projects that investigate opportunities for carbon offsetting within blue carbon ecosystems of the Corangamite Catchment region in Victoria. We aim to establish current blue carbon stocks, and identify possible mechanisms for the future management of these ecosystems that will aid in the mitigation of carbon re-mineralisation (CO2 released to the atmosphere) and climate change. Quinn is also involved in trophic cascade research. A large-scale loss of marine predators over recent decades has led to an immense change in oceanic food web structures, exerting flow on effects that are predicted to extend beyond that of faunal alterations, subsequently changing fundamental biogeochemical cycling processes (sedimentary carbon cycling). However, the empirical evidence for these flow on effects is only just coming to light, with research into trophic cascades effects on Australian seagrass carbon storage capacity still required.

Alex Pearse
Honours Student

BSc, Deakin University Warrnambool campus, 2011-2014
Alex’s research interests are in the field of freshwater ecology. He is currently working on his honours project titled ‘Variability in Australian temperate freshwater wetland carbon stocks’. We aim to identify the within wetland variability in carbon stocks to help improve sampling designs for carbon stock assessment projects. This project will also undertake one of the first carbon stock assessments of freshwater ephemeral wetlands in Australia. Alex has also been involved in work looking to identify rapid indicators of freshwater wetland health. Functional processes such as organic matter decomposition can indicate a systems health, but they are time consuming and costly to monitor. This work aims to identify water quality variables which can be used as ‘rapid indicators’ of wetland functional processes.
