PhD in Environmental Toxicology


The goal of the Toxicology program is to provide education in the development, interpretation, and utilization of toxicological data for solving environmental health problems. This requires training in basic biomedical and public health sciences such as Biochemistry and Molecular Biology, Physiology, Epidemiology, and Biostatistics, as well as more specialized studies in Toxicology, Risk Assessment, and Risk Communication. Focus on identifying, understanding, and analyzing toxic agents and their effects on human health. Research areas include neurological, hepatic, renal, and respiratory systems; prenatal and neonatal development; and carcinogenic and genetic effects of toxicants. The program also offers a strong focus on risk assessment.

Likely Careers

PhD graduates find employment opportunities in biotechnology, academic research, the pharmaceutical industry, and government laboratories.


Requirements: Baccalaureate degree, generally in science or engineering, with coursework in Physics, Chemistry, Biology, and Mathematics. GPA of 3.5 or above recommended. GPA minimum of 3.0 for last 90 credits of study. No specific subject area tests are required. Competitive applicants usually have Graduate Record Examination (GRE) scores above the 65th percentile. 
Although students may enter the program with a BS degree, a Master of Science degree in toxicology or a related discipline is strongly recommended. 

Application Deadline:  Dec. 1 for first priority review


Upon satisfactory completion of the PhD in Toxicology, graduates will be able to:

  • Meet the learning objectives for the MS degree in Toxicology ;
  • Conceive, develop and conduct original research leading to significant advances in the knowledge of mechanisms of toxic action or in the assessment of risk deriving from exposure to toxicants;
  • Apply advanced methodology to research projects in environmental health and develop new research methods to address environmental or occupational problems; and
  • Demonstrate written and oral skills by preparing papers and presentations for peer scientists and the community at large.
