Toxicology is the study of the effects of chemicals and other potentially harmful agents on biological systems. The field draws upon the sciences of biology, chemistry, biochemistry, physiology, cell and molecular biology, neuroscience and pathology. The core curriculum provides a comprehensive background in toxicology that is enhanced by elective offerings in the department and the many related basic and health science courses available at CSU. The Ph.D. in Toxicology prepares students for research careers in industry, government and academia. The emphasis is on developing the abilities of the student to progress to a career as an independent scientist.
