Laura López-Hoffman is a research professor at the Udall Center for Studies in Public Policy and a professor in the School of Natural Resources and the Environment. She is also an affiliated faculty member of the UArizona James E. Rogers College of Law. López-Hoffman is an environmental scientist working at the intersection of natural science and environmental policy. Her two primary areas of research are: data-science approaches to evaluate the outcomes and performance of U.S. natural resource laws and policies for people and the environment; and governance of endangered and migratory species.

López-Hoffman leads the UArizona team developing NEPAccess.org, a freely available knowledge-discovery and engagement platform, and increasingly a go-to resource for the U.S. National Environmental Policy Act (NEPA). NEPA’s original vision was elegant—that using science leads to better environmental and social outcomes, and better decisions arise from a participatory give-and-take between government and citizens. The data-science revolution of the last decade now allows NEPA’s vision to be implemented. The NEPAccess platform will have tools to assess the environmental and social impacts of federal projects and activities; tools to analyze formal and informal public engagement in decision-making; dashboards to summarize data like timelines to project completion; and most critically, a workspace for all citizens to engage in NEPA.

In North America, many migratory species provide benefits to people, such as controlling crop pests or supporting recreational hunting and viewing activities. Because migratory species depend on habitat in several locations, the benefits provided by the species to people in one country may depend upon habitat conservation efforts of people in other countries­—efforts that are often not compensated or even recognized by decision-makers. López-Hoffman and colleagues work to develop best practices for migratory-species governance that are societally equitable and ecologically sustainable. In 2021, this team was awarded the U.S. Department of Interior’s Natural Resource Conservation Achievement Award for their role in the Monarch Conservation Science Partnership. With colleagues at UArizona, López-Hoffman has also investigated the impact of jaguar critical-habitat designation under the Endangered Species Act on ranchers and landowners in southeastern Arizona

López-Hoffman is Associate Editor in Chief at the journal Ecosphere and leads the Socio-Ecological Systems track. In Fall 2022, she will undertake a sabbatical residence at the German Centre for Integrative Biodiversity Research (iDiv) in Leipzig.
