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.
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
