Master of Science in Toxicology

The Master of Science in Toxicology is designed for students who hold a bachelor’s degree in clinical laboratory sciences, biology, chemistry, or other related discipline from an accredited institution in the United States. The program offers a specialization in forensic/analytic toxicology. There are thesis and non-thesis options. The minimum number of semester credit hours for graduation is 36.0. Research opportunities in specialized laboratories are available at the Health Science Center and throughout Texas.


The Master of Science in Toxicology is a graduate degree program administered by the Graduate School of Biomedical Sciences (GSBS). All coursework is completed at the Health Science Center, except for a maximum of 6 semester credit hours of transfer courses that may be completed at another institution. Students in the program follow policies and procedures of the GSBS.

Frequently Asked Questions

Do I have to be a Clinical Laboratory Scientist (medical technologist) to enroll?

Students who have a baccalaureate degree in biology, chemistry, Clinical Laboratory Science or other science fields may enroll in the Toxicology track. Students who are interested in the Immunohematology track must be a CLS with experience in the blood bank.

Do I have to go full time?

The curriculum was designed for part-time as well as full time students. Students have 6 years to complete the program.

Are there stipends or teaching assistantships?

The M.S. program does not offer stipends or teaching assistantships. Those students who are not employed full time but who are clinical laboratory scientists may be able to find part-time work in clinical laboratories in the medical center area.

How many students are accepted each year?

We generally accept only 2-3 students per year because of limited practicum sites.
