The M.S. program (36 hours) is composed of coursework emphasizing the principles of toxicology, the environmental fate of chemicals, statistical approaches to study design, data handling, and data analysis, and seminars in environmental toxicology. Supplemental coursework, research, and thesis hours aHuman Factors is that field which is involved in conducting research regarding human psychological, social, physical, and biological characteristics, maintaining the information obtained from that research, and working to apply that information with respect to the design, operation, or use of products or systems for optimizing human performance, health, safety, andor habitability (Stramler, 1993). Human Factors is concerned with the application of what we know about people, their abilities, characteristics, and limitations to the design of equipment they use, environments in which they function, and jobs they perform (Human Factors & Ergonomics Society).re chosen by the student with the guidance of their committee, allowing for focus on the student’s particular research emphasis. Master’s students must perform an original research project, prepare a written thesis, and defend their work in a public defense. Research areas include Aquatic Toxicology, Ecotoxicology, Human Health Sciences, Environmental Chemistry, Biochemical and Molecular Toxicology, Infectious Disease Research, Wildlife Toxicology, Fibers, Protective Textiles, and Countermeasures to Chemical Toxins, among others.
