A Top 5 Toxicology Graduate Program

Our program is one of the oldest (running for 50+ years) and strongest research-oriented toxicology programs in the nation. We are ranked among the top 5 toxicology graduate programs in the USA, according to the National Academy of Science’s NRC Assessment of Graduate Education.

This program is housed within the Department of Environmental Medicine, but our focus is multidisciplinary and interdisciplinary. As such, faculty mentors come from over 10 different basic science and clinical departments.

Trainees who come to Rochester are able to work with a team of dedicated faculty, who are internationally recognized, well-funded, and deeply committed to education and mentoring students and postdoctoral fellows. Faculty research programs span the entire spectrum of toxicology, from molecular mechanisms and cellular processes to whole organisms and human populations.

Our program alumni have assumed significant leadership positions in academia, government, industry and other occupations related to toxicology, environmental health and public policy, and are making important contributions to research and education in these fields.

What Our Students Say...

Kristina Fenner

"My lab is interested in understanding how the environment can affect the way the immune system responds. We study this through the aryl hydrocarbon receptor, which acts as an environmental sensor. My project is focused on studying how environmental ligands, mediated through the aryl hydrocarbon receptor, can affect the response of the hematopoietic stem and progenitor cells to viral infections."
