My main research interest is to understand the distribution of life on earth (e.g. species, biodiversity, vegetation types, ecosystems) through space and time. I am particularly interested in interactions between climate and the terrestrial biosphere. This includes potential impacts of climate change on species, ecosystems and associated ecosystem services, as well as the role of the biosphere in the earth climate system (e.g. carbon and water cycling). Methodologically, vegetation and ecosystem modelling at local to global scales has been at the core of my work.
Examples of current research projects:
– EarthShape: Earth Shaping by Biota
– Ecosystem Management Support for Climate Change in Southern Africa (EMSAfrica)
– The open Climate Impacts Encyclopedia (ISIpedia)
– Developing dynamic regional to global vegetation models
– Accounting for habitat characteristics and biotic interactions in biodiversity models
– Modelling the role of fire in the functioning of the terrestrial biosphere
– Effects of plant trait variability on ecosystem stability and resilience
– Assessing the impacts of climate change on biodiversity and ecosystem Services
– Causes and ecosystem impacts of megafauna extinctions
– Impacts of climate change and air pollution on mountain ecosystems in Scandinavia, France and Spain
Examples of environmental impact assessments:
– Intergovermental Platform on Biodiversity and Ecosystem Services (IPBES), ongoing
Policy support tools and methodologies for scenario analysis and modelling of biodiversity and ecosystem services
– North Sea Region Climate Change Assessment (NOSCCA, chapter Terrestrial Ecosystems)
My work is focused on understanding the dynamics of tropical forests, its natural spatial and temporal patterns, and its response to anthropogenic pressures. In order to embrace its complexity, I use forest modelling and remote sensing as tools for tropical forest research, ultimately aiming for future applications in order to halt biodiversity loss in a future with strong human tropical presence.
I have a Bachelor’s degree in Environmental Sciences (2006), Master’s degree in plant ecology (2009) in Pernambuco Federal University and PhD (2017) in Ecological Modelling from the University of Osnabrück. I have experience in the field of ecology, with emphasis in forest ecology; ecological modelling, with focus on forest dynamics of fragmented landscapes and geographical information systems, climate change with focus on the carbon and hydrology cycles.

• RESPECT – A4: Integration of ecophysiological processes and biotic interactions within a dynamic vegetation model (LSMBio): tree hydraulics, trait diversity, tree recruitment and insect herbivory
• GEOESSENTIAL – WP4.5: Evaluate the application of EO products to inform dynamic models
The main focuses of my research are vegetation and ecosystem processes and the role of vegetation in the Earth system. To study these topics I use process-based models (primarily the Dynamic Global Vegetation Model LPJ-GUESS) applied to spatial scales ranging from regional to global. Whilst much of my work involves improving the vegetation simulations for the present day and recent past (in particular utilising the wealth of remote sensing data made available by satellites) I also study vegetation in past geological ages (the Miocene) and simulate the effects of climate change on a vegetation and ecosystem functioning in the forthcoming century.
• Climate Change Impacts in Turkish Vegetation – A BMBF-funded project in collaboration with Turkish and British partners. The overall goal is to produce a high-resolution environmental-risk map of the consequences of climate change in Turkey. Our role is to adapt the global version LPJ-GUESS to better describe the Turkish vegetation and then project the future changes to vegetation and productivity using climate data from a regional climate model. The study is performed at a 1km resolution and makes use of both remotely sensed data and field observation from Turkish partners. In particular the very high spatial resolution (1km) and the use of locally-gathered soil depth information (novel for LPJ-GUESS but critical for calculating plant-available water in arid zones) are of particular value for this regional impacts study.
• Vegetation in the Miocene – Using the output from a palaeoclimate model to provide meteorological data for LPJ-GUESS we are reconstructing the vegetation in Late Miocene (~10 million years ago) and investigating CO2 concentrations and some of the atmosphere-biosphere interactions that shaped our planet’s evolution.
• Coupling LPJ-GUESS to an Atmospheric Chemistry enabled GCM – With support from MPI Chemistry in Mainz I am working to couple LPJ-GUESS to the EMAC atmospheric chemistry model utilising the powerful MESSy interface. This work will enabled investigations of many atmosphere-biosphere interactions and feedbacks including: trace gas emissions from vegetation and fire, changing vegetation structure and function, tropospheric ozone damage to plants and Nitrogen fertilisation and emissions.
• Fire in the Earth System – I am also working to improve the process-based representation of wildfire (in particular the SPITFIRE model) in vegetation models. Fire is key in shaping the functioning and structure of large areas of the terrestrial land surface and is responsible for large carbon dioxide and other trace gas fluxes.
I am also the BiK-F liaison with the Frankfurt Cloud, a collaborative venture between Goethe University of Frankfurt and sponsors including Deutsche Bank AG and Interxion Deutschland GmbH.
As is apparent from my CV and previous publications, I am new to the area of Earth Systems Science, my previous research life was in the field of Experimental Particle Physics. I hope to bring ideas and techniques from Physics to my new endeavours.
Outside of science I enjoy playing football, various games of skill and chance, music and devil’s advocate. I also like to get out into the world and spend slightly too much time worrying about the state of things.

I am basically fascinated by the spatial and temporal dynamics of ecological processes and the anthropogenic influence on natural systems. The main focus of my current work is the macroecology of alien species with a special emphasis on the spatio-temporal dynamics of alien species spread. Together with many other invasion biologists, I establish and analyse the networks of global spread of alien species and develop models to explain the observed dynamics. But I also worked on the dynamics of global cargo ship movements and its potential changes under climate change, the analysis of long-term dynamics of planktonic species and the analysis of complex networks.
Here are some of recent topics:
– Marine bioinvasion caused by global shipping
– The global spread of vascular alien plants
– Biogeography in the Anthropocene
– Metacommunity dynamics
– Analysis of complex networks

My main interest is in the response and feedback of the carbon cycle in the land vegetation to climate change, with a special focus on boreal and temperate forest ecosystems. I am particularly interested if increases in plant respiration and forest mortality due to rising temperatures and more frequent and severe climate extremes may outweigh gross productivity increases in the future. In order to address these research questions, the monitoring of vegetation characteristics and dynamics therein by remote sensing technologies will be of vital importance. I am using remote sensing-based information on the spatial distribution of forest carbon stocks (biomass) in synergy with field data in order to evaluate, calibrate and improve global vegetation models.

My research interests are in the field of climate-vegetation interactions and human influences. This matches well with the research concept ‘Adaptive Resilience of Ecosystems’ of the BMBF-funded SPACES project ARS AfricaE (www.ars-africae.org). ARS AfricaE focuses on the effect of disturbances like land use (change) and climate change on semi-arid ecosystems and ecosystem adaptation and resilience. Within the scope of this project I am working with the dynamic vegetation model aDGVM2 with a focus on Southern African savannah. With my research I am trying to improve the representation of ecosystem fluxes (eddy covariance) and carbon cycling as well as the modelling of plant water relations, plant phenology and plant ecophysiology in the model.
