Doctoral Degree in Toxicology and Cancer Biology
Who is this program for?
A doctorate in toxicology and cancer biology is ideal for individuals interested in studying the molecular and cellular mechanisms of cancer development, as well as the impact of environmental and chemical exposures on health. Graduates often pursue careers as research scientists, regulatory toxicologists, or academic faculty, working in pharmaceutical companies, government agencies, or research institutions to develop cancer therapies, environmental health policies, and new methods for cancer prevention and treatment.
Program Overview
The Ph.D. in Toxicology & Cancer Biology prepares students to investigate the molecular and cellular mechanisms underlying toxic responses and cancer development. Through interdisciplinary coursework and hands-on research, students explore areas such as environmental toxicants, carcinogenesis, drug development, and cellular signaling pathways. Working alongside faculty experts in state-of-the-art laboratories, students gain the skills to conduct impactful biomedical research. Graduates are well-prepared for careers in academia, government, pharmaceutical and biotech industries, and other health-related research institutions.
The Department of Toxicology and Cancer Biology is a multidisciplinary unit for research and graduate education in the broad areas of toxicology and cancer biology. Our mission is to provide students with an education in toxicology and cancer biology that is based on an understanding of biochemistry, physiology, molecular biology, cell biology, genetics and systems biology. This is coupled with in-depth research experience on the mechanisms by which environmental agents cause disease, with primary emphases in the areas of cancer, cardiovascular disease, and neurodegeneration.
