Welcome to the GEOPIG Lab website! GEOPIG (Group Exploring Organic Processes In Geochemistry) is a lab group headed by Professor Everett Shock at Arizona State University that researches geochemical processes in Earth systems.
Geology - Thermodynamic Modeling - Environmental Geochemistry - Hydrothermal Ecosystems - Extremophiles - GIS - Ocean World Habitability
Everett Shock has joint appointments in the School of Molecular Sciences and also the School of Earth and Space Exploration at ASU. He earned a B.S. degree in earth sciences at the University of California, Santa Cruz, and a Ph.D. in geology at the University of California, Berkeley, working with Harold Helgeson. He is a fellow of the Geochemical Society and European Association for Geochemistry, a fellow of the American Geophysical Union (AGU), and has received the Geochemistry medal of the American Chemical Society and the Eunice Newton Foote medal for Earth-Life Science from AGU. He has research interests that span environmental chemistry, geochemistry and geobiochemistry, with current projects in hydrothermal ecosystems, hydrothermal organic chemistry, the deep biosphere, serpentinization, submarine hydrothermal systems, the geochemistry of ocean worlds, aqueous alteration of meteorite parent bodies and environmental biogeochemistry. He is a co-investigator on the MASPEX instrument on NASA's Europa Clipper mission.
Hot Springs - Serpentinization - Microbiomes in Mixing Gradients - Oceanic Crust - Hydrothermal Organics - Planetary Geology
Everett Shock and his students in the GEOPIG lab explore life as a planetary process. They combine field and lab measurements with thermodynamic models and experiments to evaluate the flow of energy and matter between geochemistry and biochemistry. The results yield quantitative predictions about how planets support life that are tested in hot-spring and serpentinizing ecosystems where reactions between water and rock supply energy and nutrients to microbial communities.
