Valentine Lab


The Valentine lab at UCSB studies the interactions among microbes and between microbes and the Earth system.  Our projects probe the global methane and hydrogen cycles, microbial physiology, and hydrocarbon biogeochemistry, with field sites from Alaska to southern Chile.  Much of our work is carried out in the natural lab just offshore from campus:  the Coal Oil Point seep field, the world’s most spectacular marine hydrocarbon seeps.

We are affiliated with the UCSB Department of Earth Science and the Marine Science Institute.
