Join the Interdisciplinary Graduate Program in Human Toxicology. Early Priority is mid-December.


Welcome to the Interdisciplinary Graduate Program in Human Toxicology at the University of Iowa!

Toxicology, as recently defined by the Society of Toxicology, is "the study of the adverse effects of chemical, physical or biological agents on living organisms and the ecosystem, including the prevention and amelioration of such largest adverse effects."

The Human Toxicology Program has a long history of providing world class mentoring and research opportunities for its students. First year students participate in three different research rotations to determine their research interests. With only seven required courses, curriculum is tailored towards the student’s interests. Graduates have found immediate employment in industry, government, and academia.
