We are a multi-disciplinary association of professionals dedicated to improving decision making under deep uncertainty. Deep uncertainty exists when parties to a decision do not know, or cannot agree on, the system model that relates action to consequences, the probability distributions to place over the inputs to these models, which consequences to consider and their relative importance. Deep uncertainty often involves decisions that are made over time in dynamic interaction with the system.

We invite decision makers, practitioners, analysts, researchers, academics, and students to join us.

Our Goals

  • Research. Improve understanding and advance the capabilities of theory, methods, and tools for decision making under deep uncertainty.
  • Practice. Help public and private sector organizations make better decisions by encouraging widespread practical application of the knowledge, methods, and tools for decision making under deep uncertainty.
  • Education and Training. Provide training and training materials for scholars, practitioners, decision makers, and the public.
  • Dissemination. Disseminate knowledge about decision making under deep uncertainty methods and tools, and their applications in practice.
  • Career Development. Help members to pursue and develop their careers in decision making under deep uncertainty.
  • Community. Provide a community and a professional network where members can share ideas, foster collaboration, benefit from support and feedback, and be inspired and energized through interactions with their peers.

SONY DSC Jan Kwakkel is an associate professor at Delft University of Technology. His research focusses on model-based support for decision making under deep uncertainty. He is the lead developer of the exploratory modelling workbench, an open source toolkit for scenario discovery and related deep uncertainty techniques. He has applied his work in various domains, including climate and water, and transport.

judylawrence Judy Lawrence is Senior Research Fellow at the New Zealand Climate Change Research Institute at Victoria University of Wellington, New Zealand. She leads research programmes on climate change impacts and implication, on resilience governance and the adequacy of institutions for climate change adaptation decision making. She has developed, in partnership with Deltares, the Netherlands, the application of the Dynamic Adaptive Policy Pathways (DAPP) planning for decision making under conditions of uncertainty. She currently is Co-Chair of the New Zealand Governments Climate Change Adaptation Technical Working group preparing a national adaptation response. She previously held senior management positions in the New Zealand government and received her PhD in Public Policy from Victoria University of Wellington, New Zealand.


julierozenberg Julie Rozenberg is economist with the Chief Economist of the World Bank Sustainable Development Group. Her research includes climate change mitigation and adaptation policies, green growth and disaster risk management. She also supports World Bank teams and clients with operations research to take climate change constraints and other long-term uncertainties into account in the preparation of projects and strategies in infrastructure sectors like energy, transport, water or urban.


SAMSUNG CAMERA PICTURES Kim Smet is a PhD researcher at Harvard University in Water Resource Engineering. Her research focuses on long-term infrastructure planning under uncertainty, exploring how we can design physical systems that have greater flexibility to adapt to future changes. She has applied elements of Adaptation Tipping Points and Engineering Options to the question of reinvesting in ageing water management systems in the United States and the Netherlands.


laurabonzanigo Laura Bonzanigo is a Policy Analyst at the World Bank, where she specializes in decision support. In particular, she helps teams use analysis and stakeholder engagement to design good long term plans and projects, despite uncertainty about climate change and other factors, and amid complex stakeholder interests. Prior to joining the World Bank, Laura was a researcher at the Fondazione Eni Enrico Mattei in Italy and before that, she worked on several irrigation management and rural development projects in the Middle East, Africa, and Central America. Laura holds a PhD in Climate Change Economics from the Ca’ Foscari University of Venice, Italy, a MSc in Irrigation and Water Management from the University of Wageningen, and a MA in Social Anthropology from the University of Edinburgh.

lkaatz Laurna Kaatz is the climate scientist and adaptation program manager for the Planning Division at Denver Water. Her primary responsibility is to coordinate climate investigations and implement the findings into the planning process. Laurna’s work incorporates many areas of water resource planning, including climate and drought planning, operational and water rights analysis, and long range integrated resource planning. Before her career at Denver Water, Laurna was a Professor of Physics at Sweet Briar College, and then went on to work as a climate science researcher with Aurora Water.
