External faculty members are leading national and international researchers who actively develop long-term collaborations with the IAS research community. They work from their home university or research institute but regularly participate in or organise IAS activities in Amsterdam. Appointments are by invitation only.
Professor of Theoretical Physics, UvA.
External faculty member, Santa Fe Institute, New Mexico.
My work focuses primarily on problems in theoretical (high-energy) physics: from quantum field theory to string theory. I have made interesting excursions to adjacent fields, like condensed matter theory and physics of the early universe. My collaborators and I have studied and solved numerous problems concerning topological defects.
Professor of Social and Organisational Psychology, Leiden University
Professor of Behavioural Economics, University of Amsterdam
Distinguished Research Fellow at the University of Oxford
My research focuses on the neurobiological and psychological underpinnings of cooperative decision making, conflict regulation, group decision making, and creativity.
For his work De Dreu received several awards. In 2018, he has been awarded a Spinoza Prize, the top science prize in the Netherlands.
Director of the Complexity Economics programme at the Institute for New Economic Thinking, Oxford Martin School.
Professor in the Mathematical Institute, University of Oxford.
My main research interest is in developing quantitative theories for social evolution, in particular for financial markets (which provide an accurate record of decision making in a complex environment) and the evolution of new technologies (whose performance through time provides a quantitative record of human achievement).
Professor of Theoretical Biology and Bioinformatics, University of Utrecht.
The aim of my research is to understand biotic systems as dynamic information processing systems at many interconnected levels. Currently my main focus is on multilevel evolution, including eco-evolutionary processes, RNA worls, genome evolution and evolution of genotype to phenotype maps. Therewith I study “evolution of evolution".
Professor of Ethics and Technology, Delft University of Technology.
My research interests are in the field of Ethics and Information Technology. I have been working on ways to make ethical considerations part of engineering design, by construing moral values as non-functional requirements that can be decomposed and specified. I have also been instrumental in putting the idea of ‘responsible innovation’ on the EU research agenda.
Director and Distinguished University Professor, Urban Studies Institute, Georgia State University, Atlanta.
My research is in global comparative urbanism, particularly the relationship between urbanization and economic development across different historical and geographical contexts. I try to reconcile the essence of urban theory with a range of empirical realities, past and present and in different world regions. As a geographer, I am interested in the spatiality of urban systems and networks at various scales.
Professor in Geriatric Medicine, Radboud University Medical Center, Nijmegen
My research focuses on complex, multicausal health problems in older people, such as dementia, and on the interventions that may improve their wellbeing. Dynamical assessment of resilience, and improvement of recovery potential is currently our target, as this plays an important role in the outcomes of all interventions we offer to older patients in our Radboud UMC.
Professor of Aquatic Ecology and Water Quality Management, Wageningen University.
I am interested in unraveling the mechanisms that determine the stability and resilience of complex systems. Although much of my work has focused on ecosystems, I also worked with scientists from other disciplines to address issues of stability and shifts in natural and social systems (e.g. the collapse of ancient societies, inertia and shifts in public opinion, and the onset of depression in humans).
Director of Research at the Italian National Research Council, Rome.
Visiting Professor of Computational Science, Harvard University.
My research focuses on the mathematical and computational modelling of complex systems at the interface between physics and biology, with special focus on flowing matter across scales, from macroscopic turbulence to micro and nanoflows, all the way down to quantum and subnuclear scales.
Professor of Public Administration and Policy, Wageningen University.
My research addresses the governance of wicked problems in the interrelated fields of food, agriculture, climate, water and energy. My theoretical work focuses on transformational change through accumulating small wins; tensions between historically grown institutions and new emerging forms of governance; and connectivity across boundaries and scales.
Full professor for Science of Complex Systems, Medical University of Vienna.
External professor, Santa Fe Institute
Part-time senior researcher, IIASA.
My research focus is on understanding of complex systems. My work ranges from fundamental physics, applied mathematics, network theory, evolutionary systems, life sciences, economics and finance and lately social sciences.
Professor of dynamics in emotion regulation and psychopathology, University Medical Center Groningen.
I study mechanisms of psychopathology and particularly dynamic patterns in emotions and behaviours in daily life. I use personal time-series models to test predictions from complex system theory and to unravel mechanisms underlying transitions in symptoms. I work with health care professionals to use this type of patient data to improve diagnostics and treatment.
