My scientific research broadly focusses on the nexus of land use, food production, biodiversity indicators and conservation planning. Specifically, I am very much interested in

  • (a) how we can bring the best-available biodiversity change estimates into decision making processes and under which circumstances win-win situations arise.
  • (b) the influence of temporal lags in our understanding of biodiversity change and effectiveness of conservation interventions.
  • (c) providing scientists and practitioners with robust environmental datasets and accurate biodiversity indicators.
  • (d) the creation of scenarios and predictions of what-if assumptions and plausible future for humankind and wildlife on this planet.

I enjoy thinking about and implementing novel approaches to better quantify the natural and anthropic world. Here I regularly use and combine remote-sensing, ecology and machine learning techniques.

You can find a full list of my scientific contributions here and key people I often collaborate with at the bottom.


Improving biodiversity indicators

On the ground management and policy practitioners require robust information on whether interventions and changes in behaviour result in measurable differences in biodiversity. Working mainly with the PREDICTS and other global biodiversity databases I have investigated how we if and how we can establish linkages between local biodiversity change and remote sensing data, thus enabling cost-effective monitoring.

Integrated conservation and land-use planning

Given a limitation of funds, it is often a question where conservation management should be implemented to best benefit both biodiversity and ecosystem services. Recently I have used linear programming and optimization tools to derive delineations of cost-effective priorities. Through future projects I am looking forward to expand on this work, particular the intersection between mapping synergies and tradeoffs between stakeholder preferences, ecosystem services and biodiversity benefits.

Mapping of land systems and ecosystems

To make adequate decisions and quantify the influence of environmental change on biodiversity and ecosystem services requires the best-available data. In various research projects I have led or been involved in creating new global and national datasets for the scientific community. Usually these data are created by either intersecting and harmonizing existing datasets or by applying innovative machine learning algorithms on remote-sensing imagery and climate variables. You can find some of the datasets that I created in the Data section.

Scenarios and predictions

In most instances, political decisions and actions have to be undertaken today if we are improve the situation in the future. In terms of policy-advise this equates to the creation of (spatial-explicit) scenarios that highlight the costs and opportunities of actions that can be undertaken. Working at IIASA I have become increasingly interested and involved in the creation of biodiversity-relevant scenarios for policy advise.
