The graduate program in Environmental Toxicology offers a Master of Science degree with a major in Environmental Toxicology and a combined degree leading to a joint J.D.Master of Science degree in cooperation with the Texas Tech School of Law.

Because of the multidisciplinary nature of environmental toxicology, prospective students should contact the graduate advisor for the program to discuss prerequisites and prior training. Generally, strong background in the natural, physical or health sciences will provide the necessary preparation. Students interested in pursuing a degree must complete applications to the the Graduate School and the Environmental Toxicology Graduate Program.

The M.S. program is composed of 36 yours of course work beyond the bachelor's level, emphasizing the principles of toxicology, the environmental fate of chemicals, statistical approaches to study design and data handling, and seminars in environmental toxicology. Supplemental course work and research and thesis hours are chosen by the student with the guidance of their committee, allowing for focus on the student's particular research emphasis. Students pursuing the M.S. degree must perform an original research project, prepare a written thesis, and defend the work in a public defense.
