Topic: Microbes in Weird Places: What Life Is Like Deep in the Earth
“Karen Lloyd studies novel groups of microbes in Earth’s deep surface biosphere, collecting them from disparate remote places such as Arctic fjords, volcanoes in Costa Rica, even deep in mud in the Marianas Trench.
Lloyd applies molecular biological techniques to environmental samples to learn more about microbes that have thus far evaded attempts to be cultured in a laboratory. She has adapted novel techniques to quantify and characterize these mysterious microbes while requiring minimal changes to their natural conditions. Her work centers on deep oceanic subsurface sediments, deep-sea mud volcanoes and cold seeps, terrestrial volcanoes and hot springs, serpentinizing springs, Arctic marine fjord sediments and ancient permafrost. She is currently an Assistant Professor at the University of Tennessee.”
