Program Overview

The Department of Biological Sciences offers research-oriented Master of Science (MS) and Doctor of Philosophy (PhD) degrees in two areas: Biochemistry and Biological Sciences. A major goal of the faculty in Biological Sciences is to provide training for graduate students who are interested in independent careers in the biological sciences and biochemistry. Biological sciences graduate students prepare for careers that emphasize an interdisciplinary approach to biology and undertake their degrees in one of the three divisions within the department. Biochemistry and Molecular Biology (BMB) offers research opportunities in areas such as the analysis of structure and function of complex carbohydrates, lipids, nucleic acids, and proteins; DNA repair; and study of extremophiles. In Cellular Developmental and Integrative Biology (CDIB), faculty conduct research in sensory and endocrine systems at the molecular, cellular, and systems level; developmental biology and cell differentiation; transcriptional regulation; intra- and inter-cellular signaling; functional and comparative morphology; neurobiology; comparative and environmental physiology. The interests of the Systematics, Ecology and Evolution (SEE) division facilitate advanced study of the ecological and evolutional processes of a broad range of organisms and habitats across the globe. Our biochemistry graduate degrees prepare students for professional careers in biochemical research and teaching in the areas of cell and molecular biology; virology; plant biochemistry; enzymology; protein/DNA interactions, structural biology and biophysics.

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 for admission are received and evaluated by the department in early January for fall admission and in early May for spring admission. Applicants must adhere to the application deadlines established by The Graduate School. It should be noted the department deadlines are earlier than those of The Graduate School. It is suggested that applications for fall admission be submitted by December 31. The spring admission deadline is April 30.

Students seeking admission must be admitted to The Graduate School at LSU and have earned one of the following degrees: BS, BA or MS in biology, biochemistry, chemistry or related fields. Candidates holding other degrees (e.g., DVM or MD) may also apply. Three letters of recommendation are required, and a minimum GPA from the undergraduate program of 3.0 on a scale of 4.0 is expected. Prospective students are required to take the GRE general test, and a score of 316 (verbal and quantitative combined) or better is expected. International students whose native language is not English must also submit an acceptable TOEFL or IELTS score.

Financial Assistance

Financial assistance is available to all fulltime students in the form of research or teaching assistantships or fellowships. To ensure consideration for financial aid, all application materials should be submitted in accordance with deadlines established by the LSU Graduate School.
