Ilonka is passionate about sustainability transitions and social innovation as well as natural building and urban planning. She holds a master’s degree in Industrial Ecology, an interdisciplinary master program focused on sustainable development in all areas of society. Her master’s thesis was on envisioning and practicing sustainability transitions in Dutch ecovillages, for which she conducted extensive empirical research in five ecovillages, focused on social innovation.


Ilonka’s passion for natural building and urban planning comes from her bachelor’s degree in Architecture, Urbanism and Building Technology. During her bachelor, Ilonka got inspired by building with only local and natural materials using simple or traditional techniques. She studied sustainable building technologies, energy systems and water solutions. For her bachelor thesis she developed a self-sufficient earth-bag dome construction using local (waste) materials.


Ilonka started working at Drift since the beginning of 2017 as a junior researcher on the research project ‘Amsterdam Builds a Coalition’. This project aims to understand how a zero-emission neighborhood can be realized in Amsterdam with the collaboration and part-ownership of the (future) inhabitants. Consequently, the project aims to implement a strategy to mobilize citizens and realize such a neighborhood.


Through working at Drift she aspires to contribute to sustainability transitions by performing action-research around sustainability topics.
