Excellence and leadership in conservation, water and watersheds, and healthy ecosystems by bridging environmental science and public policy

ESP is a growing academic and professional force spanning the twin domains of the natural and social sciences. We are focused on understanding and implementing science and public policy to address and solve complex environmental issues that challenge the integrity and sustainability of global systems.

ESP students who are trained in environmental policy, conservation sciences, climate change, aquatic ecology, wildlife management or one health, go on to professional careers in government agencies, non-profit organizations, and the private sector.
