Microbes are key players in the biogeochemical cycles of all the major elements. Most of the research conducted in the Valentine lab focuses on the interactions between microorganisms and their environment (microbial biogeochemistry). Studies in microbial biogeochemistry are highly interdisciplinary, and intersted students from any field of science will be considered. Most of the research in the lab employs modern biological and chemical tools, and many of the projects are based in marine settings.
We perform a variety of studies in order to understand biogeochemcial cycling in natural systems, including:
- Radiotracer/rate studies
- Phylogenetic and microscopy studies
- Enrichment and isolation of novel microbes
- Microbial physiology and bioenergetic studies
- Stable isotope studies
- Geochemical quantification/distribution studies
Many of our projects involve field work
in either marine or terrestrial environments. Some of our recent field
sites include:
Most students in the lab will have the opportunity to participate in ocean going research.
- Skan Bay, Alaska
- Black Sea, Turkey
- Salton Sea, California
- Coal Oil Point Seeps, California
- Hydrate Ridge, Oregon
- Eel River Basin, California
- Mission Tunnel, CA
Funding for graduate work in the Valentine lab comes from a variety of sources including research assistantships, teaching assistantships, and fellowships. The lab will take one student (at most) to start in the Fall of '04, and prospective students are strongly encouraged to apply for fellowships.
