I am co-director of the CEPB. Much of my work investigates the conditions under which scientific knowledge is integrated into the public policy process. I examine 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.
