My research focuses on human behavior and the role of governance institutions in solving collective action problems and facilitating cooperation. The collective action problems associated with environmental policy provide a laboratory for my research. My current projects include watershed management, environmental activism, agricultural best management practices, and institutional change in local governments. I also dabble in experimental economics and simulation techniques to further explore collective action theory. See a recent talk at Yale here:

We know relatively little about the conditions under which scientific knowledge is integrated into the public policy process. My research addresses this gap by examining how decision-makers obtain, interpret, and apply scientific knowledge to real-world environmental policy problems. I pay particular attention to the decisions of ground-level government officials whose day-to-day work shapes policy, analyzing how their institutional contexts affect their information and choice opportunities. Much of my current work focuses on the regulation of hydraulic fracturing (fracking); I am also interested in wetland and water policy. I use a variety of methods in my work, including surveys, interviews, social network analysis, and statistical analysis.

Ryan is a behavioural economist with CSIRO's Ecosystem Sciences, Australia. He studies social behaviours that are shaped by key environmental processes, with a particular interest in institutions for managing variability and uncertainty. He spent many years exploring the mechanisms for coping with variability in arid and semi-arid Australia. More recently he has examined the distribution of the economic winners and losers from climate adaptations, how this impedes action, and the institutions that help overcome inaction. Ryan's main approaches include game and network theory. For publications see

I am interested in the interactions between people and agricultural and semi-natural systems which they attempt to manage. In particular, I am interested in the role of plant disease in these interactions as both a target for action and a stimulus for the adoption of particular courses of action. My research group is located in the Plant Pathology Department at UC Davis. We study a range of applied and theoretical issues concerning plant diseases, usually in collaboration with other researchers and typically with some broadly economic angle to the work.

Postdoctoral Researcher

I'm a postdoctoral researcher in the department of Environmental Science and Policy. I use approaches from evolutionary ecology to study the social and cultural processes that shape individual behavior in environmental contexts. I’m particularly interested in how behavior and policy interact to shape sustainability. I use theoretical models, behavioral experiments and observational data collection using surveys and interviews to examine these issues.

I'm a post-doctoral researcher who specializes in networks science. For the Rangeland project, I wrote an interactive, electronic survey that asked Ranchers, Environmentalists, and Rangeland Professionals what they would do with a specific rangeland property. Using those surveys, and data collected from group discussions on the same topic, I am mapping individuals' cognitive networks and how these change during the group discussion. I'm also working on other projects around the lab from organizational to semantic network projects.
