The Department of Biological Sciences is functionally divided into three divisions. More information and faculty listings can be found on the BMB, CDIB and SEE pages.

Biochemistry & Molecular Biology (BMB)

The Biochemistry and Molecular Biology division offers the opportunity to obtain degrees in either Biochemistry or Biological Sciences. The diverse interests of the faculty facilitate advanced study of prokaryotic and eukaryotic molecular biology, molecular genetics, enzymology and physical biochemistry. Bioinformatics, proteomics and metabolomics, are important components of many of these investigations. Physical structure studies may include working at the nearby Center for Advanced Microstructures and Devices (CAMD), a synchrotron research center which is the only such university-owned facility in the United States.  Some more specific areas of research include:

  • Regulation of prokaryotic and eukaryotic gene expression 
  • Photosynthesis, bioenergetics and chloroplast biogenesis
  • Structure and function of carbohydrates, lipids, nucleic acids and proteins
  • DNA repair and mutagenesis
  • Enzyme mechanisms

Cellular, Developmental & Integrative Biology (CDIB)

The Division of Cellular, Developmental and Integrative Biology comprises a faculty with diverse research interests employing a broad range of approaches to study organisms across plant and animal taxa. Experimental approaches include biochemistry, molecular biology, molecular genetics, electrophysiology, live cell imaging, morphometrics, light and electron microscopy. Faculty are conducting research in the following areas:

  • Endocrine systems at the molecular, cellular and systems level
  • Organelle function, cellular differentiation and signaling
  • Comparative functional morphology and biomechanics
  • Comparative and environmental physiology
  • Neurobiology at the molecular, cellular, system and behavioral levels

Systematics, Ecology & Evolution (SEE)

The Division of Systematics, Ecology and Evolution includes faculty working with a diverse set of organisms, from microorganisms to plants and animals. Research in this area often combines field studies with laboratory work, and molecular methods and bioinformatics are standard tools of the trade. The faculty participate in a variety of projects that are aimed at a better understanding of the world in which we live, interactions among organisms and their environments, and evolutionary processes. Some of the research at LSU is centered on terrestrial tropical and sub-tropical ecosystems and coastal environments. Some examples of research areas include:

  • Classical and molecular systematics and organismal biology of prokaryotes, fungi, plants and animals
  • Evolutionary biology including population genetics, evolutionary ecology, and molecular evolution
  • Population and community ecology of temperate and tropical aquatic and terrestrial systems
  • Quantitative ecology and ecological modeling
  • Ecotoxicology and conservation biology

The Department maintains modern facilities, has access to the collections of the Museum of Natural Science and the LSU Herbarium, and is a member of the Organization for Tropical Studies. Louisiana Universities Marine Consortium (LUMCON) provides support for marine/estuarine research. LSU is one of only nine universities in the country designated as both a land-grant and sea-grant institution, and one of only a select number of universities designated as a Doctoral/Research - Extensive University by the Carnegie Foundation.
