Toxicology PhD Program

tox word boxThe Rochester Toxicology Program provides state-of-the-art graduate and postdoctoral training in the environmental health sciences and toxicology. Our mission is to educate and train the next generation of talented, independent toxicologists and environmental health scientists who are able to conduct innovative research and transform their research findings into information, resources, and tools that will be used by public health and medical professionals, as well as the public, to improve overall human health and well-being.

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...

Alyssa Merrill

"In my training, I have enjoyed the breath of information the coursework exposes you to. Having a broad interdisciplinary coursework aids in the determination of where to rotate as a first-year student by allowing you to find labs that align with interests you might have not been aware of or even known was an active area of research."
