The CRC overall brings together expertise from the University of Bonn and IDOS to study relationships between diversification at various food system levels (e.g., agriculture, markets, diets) and planetary health in Germany and Ghana, in close cooperation with the University of Ghana. The researchers come from various disciplines (e.g., agronomy, agricultural economics, sociology, environmental sciences, ecology, nutrition, human health) and are integrated into 21 different CRC projects (see www.zef.de/fooddiverse).

We invite candidates who aspire to combine the acquisition of professional experience with the preparation of a PhD dissertation in the context of the IDOS dual PhD Programme. The PhD-research is designed as part of ‘FoodDiverse’ and specifically the sub-project focusing on ‘Behavioural Strategies to diversify Food Consumption’. At its center stands empirical research in Ghana and Germany around plant-based protein intake in different social groups, discourse and policy analyses around transformational consumption behaviour. The PhD will be supervised by Prof. Dr. Anna-Katharina Hornidge at IDOS and the University of Bonn, Faculty of Social Sciences as degree-holding institution.

In its semi-structured PhD program, IDOS combines a focus on both research and policy advice and offers a blend of: a) group mentoring and training activities, b) self-organized peer mentoring among the PhD group, and c) one-on-one mentoring with the PhD supervisors and mentors. The programme ensures excellent working conditions for the successful and timely completion of the PhD studies, as well as an effective combination of project and dissertation work. As a general rule, at least 50% of the working time is envisioned to be dedicated exclusively to working on the dissertation.
