The Department of Biological Sciences encourages undergraduate students to work with professors in research laboratories and projects to obtain first-hand information about research in the life sciences. Opportunities are available in many fields including systematics and evolutionary biology, ecology and environmental biology, cell and molecular biology, and in several areas of biotechnology. These research programs have been well received in the past and have proved beneficial to both students and faculty. Students who have been involved in the research projects have received competitive grants, presented papers at scientific meetings, authored papers published in scientific journals, and have gone on to become successful medical doctors, college professors, etc. Interested students should contact faculty members with whom they will conduct research prior to advisement. Brochures describing research interests of the faculty are available from advisors or the department chairperson.
Students majoring in biology or zoology may minor in any other field (major and minor may not be in the same field). Other recommended minors, subject to approval by the department, are in such areas as chemistry, geosciences, physics, mathematics, entomology, animal science, plant and soil science, and range and wildlife management. A chemistry minor is required of cell and molecular biology majors.
For microbiology majors, the chemistry courses required for ASM approval satisfy the requirements for a minor in chemistry.
Two semesters of organic chemistry are required of all majors within this department except for biology majors under teacher education who must have at least one semester of organic chemistry. It is urged that organic chemistry be taken during the second year of study. Students whose area of interest requires a strong background in chemistry should complete a chemistry minor.
All majors must take one semester of either calculus or statistics. Cell and molecular biology majors must take one semester of calculus (MATH 1351). Microbiology majors must take either MATH 1351, 2300, or AAEC 3401.
