ResearchMy research focuses on the co-evolution of cognitive, institutional and ecological processes. I am interested how people, their institutional rules and the environment they live in fit together. In the past, present and the future, from local scales to the global scale. I mainly use computational models, like agent-based models, in combination with laboratory experiments, surveys, case study analysis and stakeholder workshops. I worked on quite a number of topics, as you can see in my list of publications. At the moment my main research interests can be divided into five categories: - Resilience and Robustness of Social-Ecological Systems (SESs) SESs experience internal and external disturbances. What are configurations of institutional rules that maintain resilience of a SES, and creates sufficient incentives for people to experiment with new practices of using natural resources? Elinor Ostrom, Marty Anderies and I use formal models to understand the interactions of resource users, public good providers and ecological dynamics. Public goods might increase efficiency of the system, but how does it affect resilience? We also start working with electrical engineers to apply robust control techniques to natural resource problems. Another approach is using a network approach to study resilience of social-ecological systems. With Jacopo Baggio, Kenny Salau, Orjan Bodin and Michael Schoon we are using an agent-based model of predators and preys on a landscape network to study effect of network structure on resilience, and how management strategies affect the resilience of these social-ecological systems. Recent papers include:

Institutional rules are not fixed, but change over time. How do people know how to change the rule and anticipate better outcomes? What kind of institutional structures might evolve given certain cognitive and ecological processes and constitutional rules? I combine agent-based models, laboratory experiments and field experiments in Thailand and Colombia. For more information on this research area I refer to the website on the virtual commons: http://commons.asu.edu/ and a project website: HSD project: Dynamics of Rules in commons dilemmas - Model-based Archaeology Why do complex societies collapse? What make people move around in the ancient american south-west? Initial work related to the collapse of one settlement. In current work, as part of a large NSF funded project at ASU, I develop stylized models to study the movement between settlements, the role of exchange networks and spatial/temporal heterogeneity of resources in the landscape.

6. - Diffusion processes People imitate behavior of others, and this can affect the way innovations spread in a population. How does the structure of social interactions, social networks, affect these diffusion processes? Wander Jager, Alessio Delre and I study the effect of the imitation processes and the structure of social networks on market dynamics. We applied this work to the success of movies using survey data and macro-level statistics. Related publications

- Health, Cooperation and Networks
As part of a project with Magdalena Hurtado, Kim Hill and Gerardo Chowell-Puente I study institutional aspect of public health, especially of indigenous communities. With Alhaji Cherif I am combining analytical and computational models from game theory with epidemiological models to study the conditions in which agents contribute to health game (instead of free-riding on the contributions of others).
