Program Description
The bachelor of science (BS) degree is designed for students who seek a rigorous, cross-disciplinary education in the physical sciences. Additional coursework is taken in the areas of biology, chemistry, physics and mathematics, providing the student with a broad scientific foundation suitable for careers in biotechnology, medicine, science-based research, health-related professions, chemical and molecular disciplines and advanced graduate studies.
Students can earn the BS in biological sciences alone, or with one of four emphases: chemistry, bioinformatics, health and medicine, or research and technology.
Learning Outcomes
Students who complete the bachelor of science in biological sciences will be able to:
- Integrate biological, chemical, physical and math principles to develop and carry out an independent research project.
- Communicate current scientific ideas effectively in both oral and written formats to a diverse audience.
- Think critically and quantitatively assess innovative, global research in a scientific discipline.

BS in Biological Sciences (80 hours)
The general degree offers the greatest flexibility, allowing students to select 16 hours of electives from any of the department's 2000+ level BIOL, CHEM or PHYS courses in addition to the 64 credits of core coursework in biological sciences listed above. No more than four hours can be applied from independent research credits, including Independent Biology Research (BIOL 4700, 4710, 4720 and/or 4730) and Independent Chemistry Research (CHEM 4700, 4710, 4720 and/or 4730).Â
Emphasis in Chemistry (82 hours)
The emphasis in chemistry is designed for students who desire to further expand and deepen their knowledge in the field of chemistry. It is particularly well-suited for students who are interested in pharmaceuticals and for those pursuing laboratory positions or graduate studies in areas involving chemical techniques. This track requires additional coursework in mathematics and advanced chemistry courses, and the electives include biology courses that contain a significant chemical component. In addition, students pursuing the chemistry track are expected to develop a senior thesis research topic that has a significant chemical basis.
Emphasis-Specific Learning Outcomes
In addition to the general learning outcomes, students who complete the emphasis in chemistry will be able to:
- Explain the molecular structure of chemical substances and the connection between molecular structure and chemical behavior.
Degree Requirements for the Emphasis in Chemistry
In addition to the 64 credit hours of core coursework in biological sciences, the following courses are required for the emphasis in chemistry:
- CHEM 3110 Biochemistry II (3 hours)
and CHEM 3111 Biochemistry II: Lab (1 hour) - MATH 1620 Calculus II (5 hours)
- Minimum of 9 credit hours of 3000+ level CHEM electives. No more than three hours can be applied from Independent Chemistry Research (CHEM 4700, 4710, 4720 and/or 4730) for this emphasis.
Emphasis in Bioinformatics (79 hours)
The emphasis in bioinformatics prepares students with a diverse scientific foundation in biology, math and computer languages, to prepare students for careers in bioinformatics that use data analysis skills, such as: biotechnology, computational biology, academic research labs, medicinal chemistry, pharmaceuticals research, agriculture technology, personalized healthcare, or any biology-related field that involves data analysis.
Emphasis-Specific Learning Outcomes
In addition to the general learning outcomes, students who complete the emphasis in bioinformatics will be able to:
- Use computational and bioinformatics methods to analyze data for studying biological processes, and relate results back to core principles in biological sciences.Â
Degree Requirements for the Emphasis in Bioinformatics
- MATH 2200 is the required statistics courses in place of STAT 3100 or PSYC 2750
For students completing a dual degree in mathematics, or a minor in mathematics that incorporates MATH 1610 Calculus I and MATH 2200 Statistics, these courses will not be required for the BS in biological sciences with an emphasis in bioinformatics. If the student drops the mathematics major or minor, the courses will be required and counted toward the BS in biological sciences.Â
In addition to the 64 credit hours of core coursework in biological sciences, the following courses are required for the emphasis in bioinformatics:
- BIOL 2000 Bioinformatics (3 hours)
- COSC 1800 Python Programming (3 hours)
- CSIS 2500 Introduction to Data Science (3 hours)
- CSIS 3300 R Programming for Data Analytics (3 hours)
