The mission of the Biology Program is to provide students with a high-quality education that includes experience with research and field projects. The program provides a scientific and technical background that empowers students to successfully pursue science and technology careers or proceed to advanced graduate studies. Faculty strive to make each student’s educational experience challenging and rewarding.
The Biology Program prides itself on its ability to place students into bioscience careers. Data suggest that our graduates are highly successful in being admitted to and completing medical, dental, and veterinary schools and graduate programs nationwide. The department attributes this success to intensive biology laboratory and field experiences with cutting-edge technology and instructors committed to individual student progress. Facilities include laboratories in physiology, microbiology, molecular biology, plant biology, and a greenhouse, as well as nearby field sites for ecological research. A computer laboratory with bioinformatics software is available for classroom and student use. Graduate students in biology are taught the practical use of common scientific instrumentation they will encounter in their careers.

The mission of the Master’s program in Biology is to provide graduate students with a high-quality science education that includes experience with research and field projects. We offer a Thesis Track MS Program centered on an individual research project guided by a graduate faculty adviser and advisory committee and a Non-Thesis Track MS Program. Our Master’s Programs provide a scientific and technical background that empowers students to successfully pursue science and technology careers, or proceed to advanced graduate studies.
The Biology Department is situated in the Ivan Hilton Science Center. Our laboratory research is fully supported with modern and continuously updated facilities including molecular and cellular lab space and equipment, a teaching and research greenhouse, and organismal wet labs. Field research in evolution and ecology is comprehensively supported by a long-term research station at the Rio Mora National Wildlife Refuge and the surrounding ecosystems of the Sangre de Cristo Mountains and Great Plains. Our teaching labs are fully equipped for inquiry and research-based biology exploration.
