Student working in a lab

The Biology Department offers students opportunities to study in the field or in modern facilities with up-to-date instrumentation and resources, including a DNA-sequencing unit, an integrated microscopy facility, high-speed digital networks and computing centers, a GIS lab, greenhouses, wet labs, and extensive plant, animal and paleobotanical collections.

Graduate study in biology integrates classroom and field or laboratory experience to help meet the current and future scientific needs of society.

“The degrees I received from Texas State prepared me well, in terms of basic knowledge and professional development, for a long career in the health professions, as well as my present teaching position. Even today I count professors in the department among my close friends.”

— Kort A. Angerstein, A.P. Biology Teacher, Victoria I.S.D.

Course Work

Students can pursue either the master of science (M.S.) in biology (thesis or non-thesis) or the master of arts (M.A.) in biology (thesis-based). Students who choose the 30-credit-hour, thesis-based M.S. program are usually preparing for professional careers, advanced graduate work, or advanced training for technology-related industries. The thesis-based M.A. program also requires 30 hours but permits non-science minors. Students who choose a non-thesis degree, such as secondary science teachers, may prefer to receive broad training in biology without a formal research experience. The non-thesis M.S. degree requires a minimum of 45 semester hours, including at least one semester of a supervised research course.

Degree Hours Thesis Option Minor Option
M.A. 30–31 Thesis Minor from outside College of Science
M.S. 45–46 Non-Thesis Minor required
M.S. 30–31 Thesis Science or Geography minor required
M.S. 30–31 Thesis No minor
M.S. 45–46 Non-thesis No minor
