General Toxicology PhD Concentration

General Toxicology Concentration Description

The General Toxicology Concentration is designed for students who desire a broad toxicology background and do not desire the specificity of the Environmental or the Molecular and Cellular Concentrations. Students electing this option may want to pursue research in more traditional areas of toxicology including fate and metabolism of toxicants, organ and cellular toxicity, endocrine disruption and analytical toxicology.  Students in the General Toxicology Option may conduct research in any area of Toxicology, but their coursework may reflect a broader base of knowledge than those within the other two subdisciplines.  For a list of faculty and a description of their research programs please visit our research page and click on the Environmental and Molecular Cellular links.
