Arthur Petersen
Arthur Petersen (1970) is Director of the Methodology and Modelling Programme of the Netherlands Environmental Assessment Agency (Milieu- en Natuurplanbureau, MNP). In this capacity, he leads the agency's efforts in methodology for sustainability assessment and methodology for uncertainty assessment and communication. Besides his job, he is Treasurer of Pugwash Netherlands. After obtaining Master's degrees in theoretical physics (1993) and philosophy of science (1995) from the Vrije Universiteit Amsterdam, he wrote a dissertation in atmospheric science entitled "Convection and Chemistry in the Atmospheric Boundary Layer" (Utrecht University, 1999). From 1999-2001 he was postdoctoral research associate in the Faculty of Philosophy, Vrije Universiteit Amsterdam, and started writing a book (and second dissertation) on the role of computer simulation in science and politics, with a case study on climate change. This book is titled "Simulating Nature: A Philosophical Study of Computer-Simulation Uncertainties and Their Role in Climate Science and Policy Advice" (2006). In 2003, he published two edited books: "Sharing the Planet: Population - Consumption - Species. Science and Ethics for a Sustainable and Equitable World" (co-edited with Bob van der Zwaan ) and "Niet bang voor onzekerheid" ["Not Afraid of Uncertainty", in Dutch] (co-edited with Marjolein van Asselt).

Juan Pablo Pardo-Guerra
Juan Pablo Pardo-Guerra (1980) is Chair of the Executive Board of International Student/Young Pugwash and a graduate student at the Science Study Unit of the University of Edinburgh. Educated as a physicist, Juan Pablo developed a deep interest in the problems posed by the inclusion of complexity in the analysis of economic systems. This interest led him to work with Christopher Stephens and Jose Luis Gordillo of the Universidad Nacional Autonoma de Mexico (UNAM) on an artificial stock market which allowed the research team to study the effects of learning, adaptation and microstructural changes on the macroscopic evolution of the system. This line of research led to the development of a statistical measure of market inefficiency based on the behaviour of the system’s agents. Furthermore, it has prooved to be an important tool in unveiling some insights into the origin of fat-tailed distributions in real financial data. The most recent results of this team's research are detailed in two papers, one on the dynamics of learning and adaptation in an artificial financial market (2004), and a more extensive one which consists of a study of Neo-Austrian economics using an artificial stock market (2004).
On a different level, Juan Pablo is currently involved in the ongoing debate on the nature of scientific knowledge and its connection with culture, politics and society in general. Juan Pablo's special interest is finding new ways to implement succesful scientific research agendas in the South not only through a reorientation of science's goals but in fact through its complete redefinition at the local level. In this respect, some of Juan Pablo's comments can be seen in publications such as the Post Autistic Economics Review and Physics Today.
