We know that microbes are the most abundant organisms on the planet and are found in every conceivable habitat. However, we know very little about what microbes are actually doing. My goals are to understand the roles of bacteria in biogeochemical cycling of important compounds in numerous habitats, from the deep sea and coastal ocean to the Arctic tundra.
The emphasis in my lab is to use genomics and transcriptomics of populations combined with measuring environmental parameters in order to understand the importance of microbes in the environment. I presently have five ongoing projects funded by national agencies (NSF, DOE, NOAA) in my laboratory: 1) measuring bacterial activity and growth rates using molecular approaches and relating activity to the environment (see Campbell et al., PNAS, 2011); we are currently examining activity in relation to biotic and abiotic factors in stream, estuarine and coastal environments (Ludovic Besaury, Nattasha Vinas, Keith Thompson); 2) using metagenomics/metatranscriptomics to investigate temporal bacterial community and activity changes in coastal and open ocean bacterial communities (Ludovic Besaury); 3) using metagenomics/ metatranscriptomics to investigate the roles of Lucinid (clams) endosymbionts in pristine and impacted coastal environments (recruiting a student); 4) developing high-throughput sequencing approaches to investigate the presence, persistence and activity of fecal indicator bacteria and potential pathogens such as Helicobacter and Campylobacter in aquatic environments (see Twing et al., Water Research, 2011, Matthew Mallard, Rachel Weber, Lillian Jones); and 5) characterizing a novel nitrogen assimilation pathway in a thermophilic deep-sea Epsilonproteobacteria isolated from hydrothermal vents as well as in human-associated campylobacters (see Campbell et al., PLoS Genetics, 2009, Caleb Ahrns, Marco Valera).
The lucinid endosymbiosis project is newly funded and in collaboration with Dr. Annette Engel, University of Tennessee, Knoxville and Dr. Laurie Anderson, South Dakota School of Mines and Technology. I am looking for a PhD student that is interested in field and laboratory work as well as bioinformatics for this project.
