Overview

Key Features

Students can specialize in Human-Environment Interactions as part of their PhD in Ecology degree plan. The Ecology – Human Environment Interactions program from Colorado State University aims to develop students as scientists and policy makers with interdisciplinary problem-solving skills focused particularly on social-environmental approaches to addressing global challenges in the ecological sciences from local to global scales.

Students specializing in Human-Environment Interactions engage in independent and collaborative research guided by advisors in the program.

Our unique interdisciplinary program allows students a variety of learning and networking opportunities. GDPE is jointly administered by CSU’s eight Colleges to engage students with expert faculty across multiple departments. As a Special Academic Unit within the university, GDPE offers a distinct graduate experience through both the breadth and depth of training that helps our graduates excel professionally.
