The graduate academic and research programs of the Department of Pathobiological Sciences (PBS) are designed to develop intellectual abilities and research skills through investigations of infectious diseases of humans and animals. The interdisciplinary faculty—with expertise in molecular biology and biotechnology of infectious diseases, bacteriology, parasitology, immunology, virology, vector borne diseases, epidemiology, and pathology—along with well-equipped laboratories and animal facilities, provide a stimulating environment for graduate training.
Depending upon their interests, students choose courses with an emphasis on immunology and molecular virology, bacterial or viral pathogenesis, parasitology and parasite-induced diseases, or epidemiology and community health. Communication skills are fostered through active research discussion groups, interdisciplinary seminars, oral examinations, presentation of papers at scientific meetings, and publication of research findings. This academic and scientific program develops scientists who are able to contribute to the improved health of humans as well as food producing, companion, laboratory, and aquatic animals.
The department offers a residency program along with a graduate degree program in both anatomic pathology and clinical pathology. A residency program in laboratory animal medicine is available through the Division of Laboratory Animal Medicine within the School of Veterinary Medicine.
Applications and supporting materials for all graduate study must be submitted through the online application site for the LSU Graduate School. Official transcripts, official test scores, and other materials that come from third-party sources must be mailed to: Graduate Student Services, 114 West David Boyd Hall, Baton Rouge, LA 70803. These paper documents are stored electronically and departments have access to all materials submitted by and/or on behalf of a student applying to graduate study.
Applications are accepted at any time but are evaluated only after all supporting documents and credentials have been received. Application should be initiated at least six months prior to anticipated entry. By the time of admission, applicants should have earned a minimum of a baccalaureate degree that includes training in general biology, microbiology, biochemistry, genetics, and inorganic, organic, and analytical chemistry. Statistics is also recommended.
Students must meet the acceptance criteria outlined by the LSU Graduate School and the following PBS requirements (GPAs are rounded to nearest tenth). Applicants must score at least 150 on both the verbal and quantitative portions of the GRE and have an overall GPA of at least 3.2 or at least 154 on both the verbal and quantitative portions of the GRE and a GPA of 3.0. Non-English speaking foreign nationals must have a TOEFL score of at least 550 on the paper-based test, 213 on the computer-based test, or 79 on the Internet-based test, an IELTS score of at least 6.5, or PTE score of at least 59. Application must include a curriculum vitae, statement of interest, transcripts, GRE scores, TOEFL/IELTS/PTE scores (for international students), and three letters of reference.
Stipends, fellowships, and assistantships from various sources are available on a competitive basis for both masters and doctoral students. Applicants seeking stipend support should submit their application by February 1 for matriculation in the fall semester and September 1 for the following spring semester.

This department offers the MS and PhD in Veterinary Medical Sciences with an emphasis in Pathobiological Sciences. Exceptional students may work toward the PhD without first earning an MS. Complete course requirements for the MS and PhD degrees in the Pathobiological Sciences are stated in a document titled “Graduate Program Guidelines” that is provided to each prospective student admitted to the program. This document is available for download on the departmental website and contains significantly more details. A synopsis of classes, etc. for the MS and PhD degree is listed below.
