About 60 faculty members belong to the Molecular Toxicology and Environmental Medicine Cluster and also participate in the Ph.D. Program in Toxicology.

Primary mentors serve as thesis advisors; their names are in red.

Resource mentors contribute to the program through teaching, serving on thesis advisory committees or seminar committees, by contributing to the training of postdoctoral fellows, and by providing research resources, but do not currently serve as primary mentors for Ph.D. students.

They include faculty with a clinical emphasis or major administrative or research support responsibilities, more senior faculty who no longer wish to serve as primary mentors to Ph.D. students, as well as more junior investigators whose independent research programs are not yet fully established.
