My primary scientific interests include different aspects of aquatic microbiology with emphasis on the role of microorganisms in the biogeochemistry of aquatic sediments, microbially induced diseases of aquatic animals and connection between the processes in sediments and epidemiology of human and aquatic animal pathogens. My students and I use both cultivation-dependent (enrichment and pure cultures) and cultivation-independent (16S rDNA and metabolic gene libraries) techniques to study various microbial communities.

The role of microorganisms in the coupling of the carbon and sulfur cycles at oxic-anoxic interfaces is of particular interest for me. My research has focused on two distinctive marine environments: the Cariaco Basin, the world's second largest permanently anoxic basin and mobile tropical deltaic muds characterized by physically reworked layers dominated by suboxic processes. I am also planning to study the role of microorganisms in the biogeochemistry of sediments from the Gulf of Mexico and Louisiana coastal marshes.Functioning of redox interfaces in coastal marine sediments may be important in understanding local ecological problems, such as anoxia in the Gulf of Mexico and Long Island Sound. Recent spread of shell diseases in Long Island Sound lobsters is triggered by several factors of which anoxia is perhaps the most important. We are working on identification of pathogens of shell disease, and physiological changes in lobsters caused by the disease. I am also planning to study diseases of several fish species commercially important for Louisiana.Environmental genomics is a new direction for microbial ecology, bacterial genomics and me. Its goal is to characterize genomes of environmentally important yet non-culturable bacteria. Genome sequencing data will demonstrate a full metabolic potential of microorganisms in question and indicate their possible involvement in biogeochemical processes in their environment. Currently we have targeted several genomes of non-cultured and cultured bacteria for sequencing. The next step will involve microarray technology and proteomics to investigate expression of genes in these bacteria in their environment.

Graduate student projects are expected to work in agreement with the general directions of the research in my laboratory. Although the work of a microbiologist is generally in the laboratory, we are going to the field for collection of samples. Students interested to work with diseases of fish will be involved in maintenance of lab-reared animals. Financial support of research projects may be available under my research grants. Graduate students are expected to publish project results in peer-reviewed journals and present data at professional conferences.
