About SIET

We are a platform of young researchers at Delft University of Technology. We are working on research projects on energy transition projects that are inherently multidisciplinary - i.e. on the boundary of technology, engineering and social sciences - and focus on manifestation of social innovation therein. We facilitate researchers within and outside Delft University of Technology who also conduct research in this field. Currently, our team consists of the following persons: Dr. Anatol Itten, Dr. Thomas Hoppe (chair), Dr. Gerdien de Vries, and Twan Kramer.

Thomas Hoppe has a PhD in Public Policy from the University of Twente. He works at TU Delft as Associate Professor per April 2016. His research line is about governance of energy transition, focusing mostly on low carbon cities and regions, and community energy. In 2011 Thomas was awarded the ‘G.A. van Poelje Jaarprijs‘ (annual award for best dissertation in the in the field of Public Administration in the Netherlands and Flanders) on behalf of the ‘Vereniging voor Bestuurskunde’ (Dutch-Flemish Association for Public Administration).

Thomas is involved in four PhD projects as a daily supervisor or promotor, and has succeeded in successfully supervising five others. He has supervised more than 90 students working on Bachelor’s and Master’s assignments, and has published over 50 articles in refereed academic journals. Thomas is involved in multiple EU projects.  

Thomas Hoppe holds a membership of the NIG (Netherlands Institute of Government studies) Advisory Council, and leads a research colloquium about energy and climate governance (since 2012). Internationally, Thomas participates in the ECPR (European Consortium for Political Research), STRN (Sustainable Transitions Research Network) and ESEIA (European Sustainable Energy Innovation Alliance). He is in the editorial board of the academic journal Energy, Sustainability and Society (ISSN: 2192-0567)

Director of the TPM Energy Transition Lab

Gerdien de Vries

After graduating cum laude from the Research Master programme Social and Organisational Psychology at Leiden University in the Netherlands, Gerdien de Vries continued to get her PhD degree in behavioural sciences at the same university. She wrote her PhD thesis on pitfalls in communications about environmental technologies. She tested – experimentally- how framing effects in these communications influence citizen perceptions. Since 2015, dr. De Vries continued her research on the interplay between psychology, technology, and public administration at Delft University of Technology. She holds the position of associate professor since 2021. With predominantly quantitative research methods including surveys and experiments, she identifies psychological mechanisms (such as cognitive biases and heuristics) that affect decision-making in complex, multi-actor settings, mainly in the “green” (energy and climate) domain. For example, she found that hassle perceptions are important reasons why people refrain from green behaviour. Furthermore, dr. De Vries designs and tests techniques that can moderate these psychological mechanisms with the use of persuasion such as framing and nudging. These techniques are applied for the design of policies, products, and systems.

Dr. de Vries is one of the founders of the SIET Platform and she holds a position as scientific director of the TPM EnergyTransition Lab. In 2020, the Dutch government appointed dr. de Vries as the Dutch expert for the international platform for energy sector behavioural insights from the IEA (International Energy Agency). She is regarded as an expert in this field due to her participation in numerous research projects on energy behaviour and her international publications on this topic. 

Dr. De Vries is often invited as a (keynote) speaker for seminars, webinars, and conferences. She also regularly vlogs and blogs about her work on climate psychology, as she finds it important to disseminate research findings to a large, international audience. Her blogs are for instance published via the London School of Economics.

Postdoctoral Researcher

Anatol Itten

Anatol Itten is a post-doctoral researcher in co-creation in sustainability transitions and mass participation of citizens in government decisions. His focal point at the Social Innovation in the Energy Transition (SIET) platform is the issue of polarization and new ways of collaboration between citizens and governments. Anatols research is further contributing to the EU Interreg SHIFFT research project, the Dutch NWO project on Participatory Value Evaluation (PVE). Anatol also teaches political theory at the University of Stuttgart. Furthermore, Anatol is a co-founder of the Disrupted Societies Institute. At the 2017 United Nations Climate Conference in Bonn, Anatol managed stakeholder engagement processes and was a citizens’ participation advisor for the German Ministry for the Environment. He is the author of Overcoming Social Division and numerous articles, amongst others, in the Negotiation Journal.

Student assistant

Twan Kramer

Twan Kramer graduated for the bachelor systems engineering, policy analysis and management with technology specialization energy and industry at Delft University of Technology. Currently, Twan started a Master of Science in Complex Systems Engineering and Management with the specialization Energy. Twan chose this specialization because of his intrest in the energy transition and in particular the transition to renewable energy.

Since 2020, Twan is working as a student assistant for Social Innovation in the Energy Transition. Twan is assisting in organizing events and he maintains the website.
