Research Interests
I strive to understand the dynamics of complex social-ecological systems under global change using dynamic modelling approaches. In particular, I focus on:- Uncovering regime shifts and tipping point dynamics in social-ecological systems
- Analyzing the impact of policy instruments and new technologies on local land-use strategies (e.g. pasture use in drylands)
- Emergence of polarization and poverty traps
- Better representing human decision-making in agent-based models
- Developing model upscaling methods
- Improving the usefulness of models to support policy and management
Current Projects
NamTip - Understanding and Managing Desertification Tipping Points in Dryland Social-Ecological Systems – A Namibian Perspective (03/2019-02/2023).
BESTMAP - Behavioural, Ecological and Socio-economic Tools for Modelling Agricultural Policy (09/2019-08/2023).
Past Projects
PostDoc in the Junior Research Group POLISES - Global food security policies and their social-ecological side effects in regions prone to global change (08/2014-10/2019).
PhD Thesis "Analyzing resource use decisions under global change by agent-based modeling." as part of the projects "emBRACE" and "POLISES".
Defended at University of Osnabrück, Institute of Environmental Systems Research on April 04, 2017.
