The Department of Biology offers degrees leading to the B.S. in Biology and M.S. in Biology. The B.S. in Biology program has two tracks; the Comprehensive track and the Pre-Health track. The goals of these programs are to support and prepare students for careers in the biological sciences, entrance into professional schools, or in education. Programs within the department encompass levels of biological organization from molecular to the ecosystem, with emphases on molecular toxicology at the graduate level. Students are encouraged to draw upon academic offering of other departments in the sciences, as well as departments in the Colleges of Health Sciences, College of Science, Engineering and Technology, among others. In addition, close liaisons are maintained with NASA, the University of Texas M. D. Anderson Cancer Center, the University of Houston and other research and academic institutions within the greater Houston area.
