About SIET

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

Thomas Hoppe is Associate Professor at TPM-TU Delft (since April 2016). His research line is about governance of energy transition, focusing mostly on low carbon cities and regions, and community energy. Thomas co-chairs a research colloquium about energy and climate governance at the NIG (Netherlands Institute of Government studies). Internationally, Thomas participates in the ECPR (European Consortium for Political Research), IPPA (International Public Policy Association), (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). He has edited multiple special issues in academic journals and a book volume on research related to social innovation in the energy transition.


Director of the TPM Energy Transition Lab

Gerdien de Vries

Dr. Gerdien de Vries is an associate professor in Climate Psychology at the Technology, Policy, and Management faculty at Delft University of Technology in the Netherlands. She also leads the Energy Transition Lab of this faculty and is one of the founders of the SIET Platform. Dr. de Vries has a social psychology background and integrates psychological theories and research methods with other scientific disciplines to unravel human behaviour in the climate and energy domain. Furthermore, she assesses how policy and technology influence this behaviour. Dr. de Vries advocates team science and open science and shares her knowledge and research insights with a large audience.


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.
