Chemical Biology and Pharmacology, B.S.

Saint Louis University's Bachelor of Science in Chemical Biology and Pharmacology is an interdisciplinary degree in which students gain a strong foundation in chemistry, biology and pharmacology. The degree is customizable to align with students' interests in medicinal chemistry, pharmacology or molecular biology.

Chemical biology is the application of chemistry toward solving biological problems, and pharmacology is the study of the action of drug molecules. The B.S. in chemical biology and pharmacology provides excellent preparation for students seeking employment in industry (biotechnology, pharmaceutical, agriculture, etc.), as well as for those who want to continue their studies in professional school (medical, pharmacy, dental, veterinary, law, etc.) and graduate school. 

Program Highlights

  • A rigorous program that makes graduates competitive for employment in STEM areas.
  • Opportunities for students to strengthen their scientific communication skills through research activities that pair an undergraduate with a faculty researcher.
  • A mentoring program that runs freshman through senior year and provides guidance and support to students.

Curriculum Overview

This program places a great emphasis on undergraduate research. Students have ample opportunity to pursue research projects under the close mentorship of a full-time faculty member in the Department of Chemistry, Department of Biology and the School of Medicine’s Department of Pharmacology and Physiology. Students use a variety of specialized equipment and computers in their laboratories and in their research. Students in upper-level courses enjoy small classes and personalized attention.

  • First year: General Chemistry I and II with labs, Principles of Biology I and II with labs, Calculus I and II
  • Second year: Organic Chemistry I and II with labs, Analytical Chemistry I with lab, Physics I and II with labs
  • Third year: Human Physiology, Biochemistry I and II with labs, Molecular Pharmacology, Physical Chemistry, Undergraduate Research, Chemistry Literature
  • Fourth year: Chemical biology electives (three selected from upper-level chemistry, biology and pharmacology coursework), Undergraduate Research, Medicinal Chemistry

Fieldwork and Research Opportunities

Benefits of this program also include career opportunities. Undergraduate students work with faculty in undergraduate laboratories as laboratory assistants.

Undergraduates who study chemical biology at SLU can attend professional meetings and present their research results. In recent years, SLU students have presented numerous talks and poster presentations at regional and national meetings of the American Chemical Society and other scientific conferences.

Careers

Career options in chemical biology and pharmacology include:

  • Education
  • Chemical research and development in industry or government laboratories
  • Pharmaceutical research and drug development
  • Biotechnology
  • Pharmacy
  • Management and administration in the pharmaceutical and biotechnology industries and health care
  • Chemical, pharmaceutical, biotech and scientific instrumentation sales

This degree provides excellent preparation for medical, veterinary and pharmacy school. Other graduates continue through law school and specialize in patent law. The public health sector is also a common area to work.

Admission Requirements

Begin Your Application

Saint Louis University also accepts the Common Application.

Freshman

All applications are thoroughly reviewed with the highest degree of individual care and consideration to all credentials that are submitted. Solid academic performance in college preparatory coursework is a primary concern in reviewing a freshman applicant’s file.

To be considered for admission to any Saint Louis University undergraduate program, applicants must be graduating from an accredited high school, have an acceptable HiSET exam score or take the General Education Development (GED) test. 

Transfer

Applicants must be a graduate of an accredited high school or have an acceptable score on the GED.

Students who have attempted fewer than 24 semester credits (or 30 quarter credits) of college credit must follow the above freshmen admission requirements. Students who have completed 24 or more semester credits (or 30 quarter credits) of college credit must submit transcripts from all previously attended college(s).

In reviewing a transfer applicant’s file, the Office of Admission holistically examines the student’s academic performance in college-level coursework as an indicator of the student’s ability to meet the academic rigors of Saint Louis University. Where applicable, transfer students will be evaluated on any courses outlined in the continuation standards of their preferred major.

International Applicants

All admission policies and requirements for domestic students apply to international students along with the following:

  • Demonstrate English Language Proficiency
  • Proof of financial support must include:
    • A letter of financial support from the person(s) or sponsoring agency funding the time at Saint Louis University
    • A letter from the sponsor's bank verifying that the funds are available and will be so for the duration of study at the University

Scholarships and Financial Aid

There are two principal ways to help finance a Saint Louis University education:

  • Scholarships: Scholarships are awarded based on academic achievement, service, leadership and financial need.
  • Financial Aid: Financial aid is provided through grants and loans, some of which require repayment.

Saint Louis University makes every effort to keep our education affordable. In fiscal year 2023, 99% of first-time freshmen and 92% of all students received financial aid and students received more than $459 million in aid University-wide.

For priority consideration for merit-based scholarships, apply for admission by December 1 and complete a Free Application for Federal Student Aid (FAFSA) by March 1.

For more information on scholarships and financial aid, visit the Office of Student Financial Services.

Non-Course Requirements

All undergraduate majors must complete an exit interview with the department chair during their final semester. B.S. majors are required to submit an undergraduate thesis and present their research prior to graduation.

Continuation Standards

The following standards apply to all new freshmen and transfer students:

  • Students must earn "C-" or better in CHEM 1110 General Chemistry 1 or CHEM 1130 General Chemistry 1 for Majors) and a "C-" or better in CHEM 1120 General Chemistry 2 or CHEM 1140 General Chemistry 2 for Majors, or the equivalent in transfer.
  • Students must earn a "C-" or better in Analytical Chemistry 1 (CHEM 2200 Analytical Chemistry 1).

Students who do not earn a "C-" in any of the identified courses must retake the course at SLU in the following semester. If a "C-" is not earned on the second attempt the student will be dismissed from the major. A student who withdraws from one of these courses on the first attempt will only have one more attempt to earn a "C-."

Students must maintain a 2.00 grade point average (GPA) in their major (CHEB or CHEM) and required related courses (BIOL, PHYS, MATH, etc.). If a student falls below a 2.00 major GPA, the student must meet with the program coordinator to review their academic performance. If the student cannot raise the major GPA to 2.00 in two semesters, the student will be dismissed from the major.

Roadmaps are recommended semester-by-semester plans of study for programs and assume full-time enrollment unless otherwise noted.  

Courses and milestones designated as critical (marked with !) must be completed in the semester listed to ensure a timely graduation. Transfer credit may change the roadmap.

This roadmap should not be used in the place of regular academic advising appointments. All students are encouraged to meet with their advisor/mentor each semester. Requirements, course availability and sequencing are subject to change.
