Birgit likes exploring nature and using wild plants for cooking and colouring wool.
Name: Dr. Gunnar Dreßler
Keywords: agent-based modelling, mobility, polarization, human decision making, resilience, remote sensing
Gunnar is a Postdoc at the Department of Ecological Modelling of the Helmholtz Centre for Environmental Research. Within POLISES, he focuses on aspects of mobility of pastoralists and livestock and how polarization between different pastoralist groups can arise, respectively how policy instruments can be used to reduce the inequality between poor and rich herders. He is also interested in the representation of human decision making in agent-based modelling.
In 2010 Gunnar joined the UFZ and has since then worked in the collaborative research centre “Difference and Integration” and the EU FP7 research project “emBRACE – Building Resilience Amongst Communities in Europe”. He graduated from the University of Greifswald in 2011 and holds a Diploma in Biomathematics. For his Diploma thesis he worked with researchers of the University of Maryland on an analysis of spatial and temporal patterns of global vegetation dynamics, using remote sensing data. Gunnar loves photography, good coffee and trying out new delicious baking recipes.

Name: Filipp Grcondciel
Position: Master’s student
Keywords: Socio-ecological-economic & agent-based modelling, poverty traps, human decision making
Filipp is a master's student in physics. He is interested in complex systems and system dynamics, particularly the application of mathematical-physical methods to socio-ecological problems. During his training he wants to learn something about the dynamics of poverty traps.
Filipp did his bachelor and is now working as a student assistant in the surface/interface science section in Halle (Saale). A scholarship from the Hans Böckler Foundation gave him the opportunity to study and engage in socio-political areas like intercultural exchange or anti-racism.
Name: Martin Kraus
Position: Research Assistant
Martin has studied Mathematics in Würzburg and Jena. After going deeper and deeper into abstraction for six years, he decided to have a closer look on application now. The topic of his internship at POLISES is how different types of farmer behaviour can change land use. He is strongly interested in methodological questions regarding agent-based modelling as well, and, being still at the beginning of his journey into applied sciences, he will broaden his interest and maybe find a topic and a supervisor for a PhD position afterwards.
In his spare time Martin likes making and listening to music, reading and social activities of any kind.
Name: Hendrik Gelsmann-Kaspers
Position: Master’s student
Duration: December 2016 - December 2017
Hendrik studies Environmental Systems and Resource Management at the University of Osnabrück. In 2017, he wrote his master thesis at POLISES, in which he compares different risk-coping strategies of pastoralists with respect to their long-term ecological and economic impacts. He is interested in modelling human decision-making using the agent-based approach and in searching ways for a system transformation towards a sustainable world.
Hendrik likes football, reading the newspaper with a cup of coffee, and discussions of political and sustainability issues.
Name: Niklas Hase
Position: Research Assistant
Duration: January 2015 - August 2016
Keywords: Social Network Analysis, Risk-sharing Networks, Mathematics
Niklas Hase was a Research Assistant at the Department of Ecological Modelling of the Helmholtz Centre for Environmental Research for 20 months. From 2007 to 2014, he studied Mathematics at the University of Leipzig. Within POLISES, he explored social-ecological side effects of policy instruments in eastern Africa. To do so, he used Social Network Analysis to understand the interplay of informal insurance within risk-sharing networks of pastoralists and formal insurance schemes like index-based insurance.
Name: Falk Hoffmann
Position: Research Assistant
Duration: September 2017 - June 2018
Falk was studying physics in Tübingen when he joined the Department of Ecological Modelling (UFZ) for his Diploma thesis in 2014. Guided by Birgit’s supervision, he investigated polarization among pastoralists due to agent heterogeneity in an agent-based model of Gunnar’s. Afterwards, he left for modelling urban heating systems within the BMBF project “Energy-efficient city Delitzsch” and for gaining experience in evolutionary multi-objective optimization at the Department of Computational Landscape Ecology. Since autumn 2017, he has rejoined to help Birgit prepare an international workshop to be held in March 2018: “Modelling approaches to enhance food security: Synergies from bridging the gap between the micro and the macro scale.”
Apart from that, he is part of a community-supported agriculture project and plays ultimate frisbee. Further fields of interest include philosophy, some politics and alternative forms of society.

Name: Kristian Liebscher
Duration: October - December 2016
I just finished my studies of maths and politics at the Universities of Dresden, Leipzig, and Torino (Italy). Now I wish to better get to know the interaction between these two spheres of science and policy instruments during my internship here at POLISES. Therefore, I'd like to help create an educational game that shows the impact of our consumption behaviour here in the industrialized countries on pastoral-nomadic systems in the global south, and learn more about agent-based modelling as a possibility of simulating unintended political and financial side effects.
In addition, I like to explore alpine passes or abandoned industrial areas by bike, cook pasta fresca, and chop wood.
Name: Jakob Lochner
Duration: October - December 2017
Jakob studies physics at the University of Leipzig and did his Bachelor at the University of Göttingen. In particular he is interested in techniques to teach complex topics from science. Thus he is doing an internship in the POLISES group and develops a concept for a web based learning game, which teaches secondary class students the global links between decisions of themselves as consumers and food security in the global south.
Jakob likes walking through nature, cooking and hiking in the mountains.
Name: Andreas Ruby
Duration: January - April 2016
I study Geography and NwT (natural science and technology) in Tübingen. Normally, with my studies, I'm going to be a teacher in secondary school, but for my orientation and knowledge I prefer to make my experiences outside of the educational system of Baden-Württemberg.
From January through April 2016, I was part of the POLISES group, working on (board) games about the issue of land use by smallholders in developing countries.
