Interdepartmental Undergraduate Progams

Environmental Science provides an integrated, quantitative, and interdisciplinary approach to the study of environmental systems. The magnitude and complexity of environmental problems are creating a growing need for scientists with rigorous, interdisciplinary training in environmental science. The Environmental Science program is designed to prepare students for positions of leadership in this rapidly changing discipline. Environmental Science graduates have a solid foundation in biological and physical natural sciences and the specialized training necessary for integrated analysis of environmental systems.

Undergraduate Study

The Environmental Science undergraduate major is offered through both the College of Agriculture and Life Sciences and the College of Liberal Arts and Sciences.  Environmental Science majors complete foundation courses in biology, chemistry, earth science, geology, physics and mathematics, plus a major consisting of an integrated course of Environmental Science courses in the first two years of the curriculum. The upper level course courses emphasize a dynamic systems approach that provides a framework for integrating physical, chemical, and biological aspects of environmental systems.

Students seeking an Environmental Science major complete the following:

1. A foundation of approved supporting courses in science and mathematics including biology, chemistry, earth science, physics, calculus, and statistics.

2. 27 credits of course work in the major, including the Environmental Science core:

ENSCI 110Orientation to Environmental Science1
ENSCI 201Introduction to Environmental Issues2
ENSCI 250Environmental Geography3
ENSCI 381Environmental Systems I: Introduction to Environmental Systems3
ENSCI 382Environmental Systems II: Analysis of Environmental Systems3
Approved Environmental Science coursework15
Total Credits27

A combined average grade of C or higher is required in courses applied in the major.

Graduate Study

Environmental Science offers an interdisciplinary graduate program leading to the M.S. and Ph.D. degrees with a major in Environmental Science. Faculty from the colleges of Agriculture and Life Sciences, Engineering, and Liberal Arts and Sciences cooperate to offer courses and research opportunities covering a broad array of environmental topics.

Applicants should have completed an undergraduate or masters degree in one of the biological, chemical, physical, or engineering sciences or should have equivalent preparation.

The Environmental Science graduate program emphasizes fundamental concepts and research, which at the same time address major environmental issues. The curriculum is designed to provide the interdisciplinary approach needed in Environmental Science education and research. In addition to work in their chosen area of specialization, students are afforded a broad exposure to the biological, chemical and physical aspects of environmental systems and the specialized training necessary for integrated analysis of these systems.
