The Department of Biology values teaching and research as equal and essential components of the education of our students and seeks to integrate research with teaching at every possible opportunity in the curriculum. Housed in the Ivan Hilton Science Center, students enjoy modern laboratories and instrumentation. 


Resources and Facilities
The department is housed in the new Ivan Hilton Science Center. Modern laboratory research spaces with state-of-the-art safety and teaching features provide students with hands-on, student-centered learning environments. Chemical instrumentation includes a high-field nuclear magnetic resonance spectrometer, X-ray diffraction equipment, gas and liquid chromatographs, mass spectrometers, IR, UV, and visible spectrophotometers, and laser spectroscopy facilities. Students who major in chemistry are expected to become fully competent in the use of the instruments by the time they graduate. Students gain a practical perspective on chemistry through involvement with research projects. Graduates of the program are prepared to pursue exciting careers in industry and government, or advance to doctoral studies.
