How do farmers, resource users, and consumers make decisions? What is the impact of institutions, and social norms on decision-making? How can we devise better tools and methods to understand human behavior? These are some of the questions I am addressing in my research.
I am the course leader and examiner for "Experimental Methods for Economics and Business Studies" (NA0185) and "Quantitative Finance" (FÖ0459). I am teaching parts of the course "Value Chains and Networks in the Bio-Economy" (FÖ0454). From 2019 to 2021, I was the thesis examiner for B.Sc. and M.Sc. theses in Economics (EX0903, EX0905, EX0907), and I regularly supervise theses in Economics and Business Studies.
Before joining SLU, I have taught different courses at Bachelor and Master level at Humboldt-Universität zu Berlin, e.g., "Introduction to Microeconomics" or "Behavioral and Experimental Economics of Agriculture and the Environment." I have also supervised several graduate theses, and I have been a frequent member of PhD committees at Humboldt-Universität zu Berlin, Germany.
Primary research fields: Experimental Economics, Behavioral Economics, Economic Psychology, Agricultural Economics
Secondary research fields: Environmental Economics, Institutional Economics, Non-market Valuation, Renewable Energy, Cooperatives
Externally funded projects: I coordinate a work package on consumer demand in a project on the potential of protein crops in Sweden (IMPULSE) (funded by Formas), and I also co-lead a work package on behavioral aspects of agri-environmental contracts in the project Contracts2.0 (funded by the EU). I lead a work package on farmers' behavior and coping strategies in a project on climate-resilient agriculture. I coordinate a work package in the project "Economic policy instruments to reduce greenhouse gas emissions from the Swedish food sector" coordinated by Sarah Säll, a work package on preferences for renewable energy investments in real estate in a project funded by the Swedish Energy Agency (coordinated by Erik Gråd), and a work package on a field experiment on household waste (coordinated by Efthymia Kyriakopoulou).
I received my Master's and PhD degrees in Agricultural Economics from Humboldt-Universität zu Berlin (in 2010 and 2015). Before taking the position at SLU, I was a Postdoc at the Leibniz Centre for Agricultural Landscape Research (ZALF). I have also worked as a research fellow at the Leibniz Institute of Agricultural Development in Transition Economies (IAMO) and the Department of Agricultural Economics at Humboldt-Universität zu Berlin.
