The mission of the Department of Biological Sciences is to instill in students an understanding and appreciation of the common thread that connects modern biological study at all levels, from molecules to ecosystems. We strive to actively engage students in the process of scientific investigation, develop their spirit of inquiry, strengthen their ability to explore in both field and laboratory, hone their analytical and quantitative skills, and foster their capacity to communicate effectively with professional peers and the public. By helping students become independent thinkers and intellectually vibrant individuals, we hope to enable them to achieve a lifetime of personal and professional success and service to society.

Biology today encompasses a very broad range of knowledge, from atoms and molecules to large-scale ecological interactions. As a result, the department supports a variety of life science programs at Moravian: biochemistry, environmental studies and sciences, neuroscience, nursing, and rehabilitation sciences. The program in biology at Moravian College emphasizes the importance of gaining appreciation for, and some mastery of, all aspects of modern biology as well as the interdisciplinary connections across the sciences. This broad base of knowledge gives our majors the ability to succeed in all arenas calling for biological expertise: teaching at all levels; academic, government, private, and industrial research; science journalism and law; professional fields such as medicine, veterinary medicine, dentistry, and optometry; allied health areas such as physical and occupational therapy; and graduate study.

Biology majors use contemporary methodological approaches in laboratories, learn about the intricacies of the subject in class, and discuss recent research findings in seminars and other upper-level courses. All students are encouraged to participate in an independent study or Honors project, in which they work closely with a member of the biology faculty on an original research topic. In addition, students may participate in internship opportunities to see how they might put their education to use after graduation.

The Major in Biology

The major in biology consists of nine course units, including Biology 112, 119, 210, either 265 OR 328, and 370. The remaining four courses are selected by the student in consultation with the major advisor; at least three of these courses must be at the 200-level or higher. Students also may earn elective credits by taking Special Topics, Independent Study, Internship, and Honors in Biology. At least three of the student’s elective courses must have an associated laboratory and/or scientific research component. Only one external internship can count as a biology elective. Biology 100, 102, 103, 104, 107, 205, 206, and 209 do not count as courses in the major or minor. The student who majors in biology must take Mathematics 106–166 or 170 or 107, Chemistry 113–114 and Chemistry 211–212. Students considering graduate work in biology or medical sciences should take Physics 109–110 or 111–112.

The Minor in Biology

The minor in biology consists of five course units: Biology 112 or 119 and four additional courses, three of which must be at the 200-level or higher. Biology 100, 102, 103, 104, 107, 205, 206, and 209 do not count toward the minor.

The Interdepartmental Major

The six courses that compose Set I of the interdepartmental major in biology include Biology 112 or 119. The remaining courses in biology and the six courses of Set II are selected by the student with the approval of the advisor.

Departmental Recommendations

Students considering graduate work in biology or the medical sciences should consider courses in economics, statistics, and computer science.

Students seeking certification to teach biology in secondary school must complete the requirements for a departmental major with a GPA of at least 3.00. Students also must complete the requirements for certification described under education and science education. Students interested in combining biology and general science certification should consult the requirements for general science certification under science education.
