Professor Yadvinder Malhi CBE FRS
Professor of Ecosystem Science and
Academic Director, MSc in Environmental Change and Management

As Professor of Ecosystems Science at the School of Geography and the Environment, and Programme Leader of the Ecosystems Group at the Environmental Change Institute, Yadvinder’s research interests focus on understanding the functioning of ecosystems and how it is altered by processes of local and global change.  He has a particular interest in tropical forests.

The broad scope of Yadvinder’s research interests is the impact of global change processes such as atmospheric change and direct human modification on the ecology, structure and composition of terrestrial ecosystems, and in particular temperate and tropical forests. This research addresses fundamental questions about ecosystem function, diversity and dynamics, whilst at the same time providing outputs of direct relevance for conservation and adaptation to climate change. His group applies a range of techniques including field physiological studies, intensive and long-term ecological monitoring, quantitative and qualitative social science methodologies, satellite remote-sensing and GIS, ecosystem modelling, and micrometeorological techniques. He coordinates an extensive and expanding research programme in Asia, Africa and particularly across the Amazon and Andes region. He also runs an active research programme at Oxford University’s Wytham Woods research site. He was co-founder of the Amazon Forest Inventory Network (RAINFOR) which has resulted in over 50 publications. In recent years he has developed an international research network (GEM: gem.tropicalforests.ox.ac.uk) collecting data on ecosystem function in a number of research sites across the tropics.

Dr Imma Oliveras
Departmental Research Lecturer in Ecosystems Science/Deputy Programme Leader

Imma’s research interests are to decipher how and why tropical vegetation structure and dynamics change across abiotic gradients and the consequences of these changes are at the community and ecosystem scale. As such, her work focuses on exploring how changes in the abiotic conditions driven by global change – and particularly increases in extreme drought events and modified fire regimes – affect plant functional traits and how this aggregates to diversity and ecosystem functioning using remote sensing approaches. She has ongoing projects in several countries of the tropics, including Brazil, Colombia, and Ghana.

Dr Constance McDermott
Jackson Senior Research Fellow in Land Use and Environmental Change
Ecosystem Governance Group Leader


Connie’s research addresses the governance of forests and land use change at multiple scales. It examines both "new" and “old" governance institutions, from market-based initiatives such as forest and carbon certification to sovereign state-based and traditional community-based approaches, to better understand how dynamics of trust and power shape environmental and social policies and facilitate or inhibit desired outcomes. Connie’s work at ECI and the Oxford Centre for Tropical Forests has focused on the multi-scale enactment of a range of international initiatives, including Reduced Emissions from Deforestation and Degradation (REDD+) initiatives, the EU Forest Law Enforcement and Governance (FLEGT) Action Plan, and government and private sector ‘zero deforestation’ pledges addressing the role of global commodities in driving land use change.

Course Director of the MSc/MPhil in Environmental Change and Management

Mark is interested in addressing inter-linked social and environmental challenges through interdisciplinary research and teaching. He is broadly engaged with research that investigates issues of well-being, inequality and justice with respect to climate change and natural resource governance. He is interested in how different values and knowledges interact with institutional and cultural contexts in driving the governance decisions which underpin environmental and social change across a range of scales. Previously Mark worked as a post-doctoral researcher working on the Ecosystem Services and Poverty Alleviation (ESPA) ECOLIMITS project. This interdisciplinary project investigated the linkages between ecosystem service provision and the multiple dimensions of poverty in coffee- and cocoa-dominated agricultural settings, focusing on Ethiopia and Ghana respectively.

Dr Nicola Stevens
Trapnell fellow in African Environments

Nikki’s research interests are centred around understanding vegetation dynamics in African savannas and how they are likely to change given increasing global change pressures like altered fire and herbivory regimes against a backdrop of changing CO2 concentrations. Along this vein I have become particularly interested in the phenomenon of woody encroachment where open ecosystems across the tropics are being invaded by native woody species. It has also driven me to improve our ability to predict future species ranges under global change by improving our mechanistic understanding of range edges in disturbance limited systems. She has ongoing projects in Southern Africa with the hopes to expand this research to other tropical savannas.

Jesus Aguirre 2.jpg

Dr Jesús Aguirre Gutiérrez
Post Doctoral Researcher

Fulford Junior Research Fellow

Somerville College

Jesús is a post doctoral researcher interested in understanding how historical and present environmental conditions shape the current distribution of species at local and global spatial extends and how species traits help them adapt or shift towards suitable locations. To investigate this, Jesús uses different field collected data on plant and insect functional traits, vegetation censuses and statistical modelling approaches. Currently, Jesús is investigating the effects of a changing climate on the distribution of plant functional traits in Latin American forests under de ‘Arboles’ NERC-funded project. In this project he also uses drone and satellite (Sentinel-2) multispectral remote sensing to track plant functional types across broad spatial extents.

Dr David Bauman      
Post Doctoral Researcher

David is a postdoc researcher working on the way climate and soil variability influence tropical tree growth and mortality rates at multiple spatial scales.  During his PhD (Université libre de Bruxelles), he focused on the spatial analyses of ecological data, and contributed to the optimization of the statistical performances of

multiscale spatial eigenvector-based analyses and variation partitioning. The overall aim of this research was to address the processes of tree community assembly and species coexistence in spatially-explicit ways. David also studied the impact of fine-scale soil heterogeneity on tree community assembly in African dry woodlands (Miombo).

His interest in forests’ response to changes in their environment brought him to the Ecosystems Lab, to investigate how tree demographic performances, or vital rates (i.e. growth, survival, and recruitment) are influenced by the interplay of species functional traits, climate, topography, and soil, in the tropical rainforests of Australia. This work is part of the ‘Tropical Forests in the Changing Earth System’ project.

Dahsjo, Cecilia.jpg

Dr Cecilia Dahlsjö
Post-Doctoral Researcher 

Cecilia is a NERC funded postdoc with 10 years’ experience of field based ecological research in both tropical and temperate forest ecosystems. Her main focus is on bottom-up approaches to ecosystem functioning with a particular interest in invertebrates as drivers of habitat stability. She is currently managing an interdisciplinary project examining the ecological impact of ash dieback in Wytham Woods. The majority of the European ash tree (Fraxinus excelsior) is disappearing across the continent due to the introduced fungal pathogen Hymenoscyphus fraxineus. This mass mortality event is expected to have a major effect on woodland habitat structure, nutrient cycling, and animal connectivity and behaviour. With an increase in global trade and climate change, pathogen driven mortality events like this are likely to become more frequent. Through long-term monitoring and experimental set-ups, this project will enable better understanding of mass mortality events and enhance management practices to both prevent and improve future scenarios.

Dr Guillaume Delhaye

Post-Doctoral Researcher

Guillaume is a plant ecologist working in community assembly and dynamics. His main focus is the coordination between functional traits and how it changes along environmental gradients. In particular, he looks at how inter-specific functional trade-offs vary in response to climate and determine the composition of tropical tree communities. During his PhD, he studied the ecological processes acting in plant communities of copper rich ecosystems in the Democratic Republic of Congo. He investigated the variation in functional and phylogenetic diversity along metal gradients, with a special focus on the relationships between traits at the inter- and intra-specific and inter population levels. He completed his PhD thesis in 2018 at the Université Libre de Bruxelles where he was also a teaching assistant in ecology, botany and biology for six years.

Dr Elizabeth Le Roux

Royal Society Newton International Fellow

I am a Royal Society Newton International Fellow from South Africa, working on large mammal communities and their impact on ecosystem processes in African savannas. My work addresses questions in trophic ecology, foraging ecology, animal-plant interaction, predator-prey dynamics and conservation biology.  I am particularly interested in the ways in which large mammals transport nutrients, such as nitrogen and phosphorus, across the landscape. I explore how this function may be modified by aspects such as the functional diversity within species assemblages and the vulnerability to and fear of predation. Currently I am working on estimating and characterizing system-wide large mammal nutrient movement through the use of an agent-based model of a virtual mammal community in a simulated savanna environment.

Dr. Jeppe A. Kristensen

Postdoctoral Researcher

Carlsberg Foundation Visiting Fellow

Jeppe is a physical geographer currently interested in how animals regulate ecosystem biogeochemistry and climate change feedbacks. In times of climate change, much research is on biological responses to abiotic drivers, however, Jeppe is particularly fascinated about how animals themselves modulate their physical and chemical (abiotic) environment as ecosystem engineers. Most of his research has been centered around soils in the interface with landscape ecology, geoarcheology, and geochronology. Jeppe’s scientific contributions include the use of burial mounds in Scandinavia as paleoarchives for prehistoric soil C content, quantification of termite biotubation in African savannahs and forests using sediment dating techniques, and the impact of insect herbivores on biogeochemical cycling in the Subarctic. During his fellowhip in Oxford, Jeppe will assess how large herbivore introduction (megafauna rewilding) affects soil C dynamics, with his primary field site being the Pleistocene Park in Siberia (project: HERBIVARC). He has previously worked at the University of Copenhagen (Denmark), Wageningen University (Netherlands), and Lund University (Sweden).
