Short CV

Sonja Geiger studied psychology at Humboldt-Universität zu Berlin and received the related diploma in 2004. She then did her doctorate in cognitive psychology at Universität Potsdam in 2007 with a subsequent Post-Doc employment at the Cognitive Science Lab of the University of Western Australia, Perth Australia.

She embarked on the path towards environmental psychology when she was working several years for the NGO „Amigos de la tierra“ (FOEI Argentina) in Buenos Aires, Argentina, where she lived from 2008 to 2012 and contributed with her experience in environmental issues in South America to a first research project on environment and psychology at the UBA (Universidad de Buenos Aires).

At various universities Sonja Geiger gained teaching experience between 2011 and 2014 (UIA, Buenos Aires, SRH Berlin) in socio-empirical quantitative methods, the fundamentals of General Psychology as well as courses on environmental psychology with regard to sustainability and society.

Since March 2015 she works on the research project Education for Sustainable Consumption through Mindfulness Training (BiNKA) funded by the Federal Ministry of Education and Research (BMBF). Since March 2015 she has also been working for the Department of individual differences and psychological assessment of the University of Ulm in the living lab "Sustainable transformation of the textile industry in Dietenheim"

Research areas:

  • psychological factors for sustainable behavior environment knowledge, time perspective, attitudes and values
  • measurement theory and construction of scales for psychological constructs
  • judging and taking decisions (behavioral economics) --> environmental issues as fraught with risk, complex issues
  • current environmental issues in the global context
