The Natural Resources and Earth Science Systems Ph.D. Program offers limitless opportunities to explore ideas and conduct research at a Carnegie Classification R1 university.

In an effort to foster deeper interdisciplinary understanding of environmental and natural resource challenges and solutions at local, regional and global levels, our students integrate life, physical and earth sciences with sociology, psychology and philosophy (College of Liberal Arts), environmental policy and ethics (Carsey School of Public Policy), and economics, social entrepreneurship and sustainability (Paul College of Business and Economics).

NRESS Ph.D. dissertations reflect the wide range of research topics related to environmental and earth system science and policy. The program is very flexible, facilitating interdisciplinary research, but not requiring it.  Guidance and Dissertation Committees work with each student to develop his or her own Ph.D. research project.  These committees draw on NRESS faculty and professors from other departments, institutes, schools and colleges across the university, as well as outside expertise.

The NRESS Ph.D. Program is very proud of the over 80 UNH faculty members who advise, mentor and serve on numerous guidance and doctoral committees for nearly 65 NRESS students. NRESS faculty are drawn from the entire university, currently comprised from UNH's research groups, departments, schools and cooperative extension.
