Molecular Microbiology and Immunology, Ph.D.

Saint Louis University's Department of Molecular Microbiology and Immunology (MMI) offers a graduate program in molecular and cellular virology and immunology leading to a Ph.D. degree. The program's goal is to graduate exceptionally well-trained researchers who are prepared for a career in academic science or biotechnology. Research in the MMI doctoral program is diversified. Areas of research emphasis include cell and molecular biology, virology and immunology.

SLU's state-of-the-art research laboratories are located in the Doisy Research Center and basic science departments in the Saint Louis University School of Medicine

The primary and secondary faculty in the molecular microbiology and immunology department have strong independent research programs funded by the government, research foundations and industry. The faculty serve on national peer-review panels and journal editorial boards and often are invited to present research at other institutions. Their research is published in highly visible scientific journals.

Curriculum Overview

Graduate instruction in the MMI program includes:

  • Advanced coursework
  • Training in scientific writing and oral presentation skills
  • Training in teaching skills for students interested in an academic career
  • Performance of original biomedical research leading to scholarly publications and the Ph.D. dissertation

Each Ph.D. candidate will have a least one primary mentor within the department with whom they will conduct dissertation research.

Students with a bachelor’s degree may enroll in the doctoral program following completion of the year-long basic biomedical sciences core program. This one-year program provides a strong foundation for subsequent specialization in microbiology and/or immunology and allows students to rotate through various laboratories in the medical center before choosing a specific field of study.


Graduates with a degree in molecular microbiology and immunology are prepared for diverse careers in industry, government or academia.

Admission Requirements

A Bachelor of Science, Bachelor of Arts, Master of Science, Master of Arts, or doctoral degree is required, including coursework in the biological sciences, organic chemistry, and mathematics. Most students enter the program following one year in the core program in the basic biomedical sciences, although direct application to the program is possible for applicants with an advanced degree.
