Special Interest Options

Students in the Biological Sciences track also have the option of pursuing one of the following special interests. Contact the preprofessional adviser by the end of the sophomore year to be assigned an appropriate faculty adviser.

Clinical Laboratory Science and Medical Technology

Students in any biological sciences major track may choose to enter a clinical laboratory sciences internship provide they have taken Microbiology (BIOS 3210), Immunology (BIOS 4860, 4865), and Human Physiology (BIOS 3450). The internship year in a licensed clinical facility qualifies a student to take the American Society of Clinical Pathologists registry exam to become a registered medical technologist. The program prepares students to work in hospitals, public health facilities, forensic biology organizations, and medical diagnosis laboratories, or to go on to graduate or professional education. Students registered at Ohio University may count courses taken during this period toward total credit hours in Biological Sciences.

Exercise Physiology

Students interested in exercise physiology may take courses designed to prepare for graduate studies in exercise or applied physiology. These students should take Human Anatomy (BIOS 3010), Human Physiology (BIOS 3450, 3455), and Physiology of Exercise (BIOS 4450, 4455). Biomechanics and Applied Kinesiology (EXPH 3200 and 3205) is also highly recommended.

Neuroscience

Students interested in graduate study in neuroscience or neuroscience research in conjunction with a health professional career should consider this option. Specialized neuroscience courses are required in the junior and senior years. Students are strongly encouraged to pursue undergraduate research, since neuroscience careers almost exclusively involve research. Stipends and support for research are available, by application, during the summer of the third year.
