background

Earth sciences

Mark Conrad

geophysicist

As head of the Geochemistry department, Mark Conrad focuses his research on using stable isotope measurements of groundwater and soil gas to identify areas of microbial activity, especially pertaining to bioremediation.

Don DePaolo

geologist

Don DePaolo's research interests focus on using naturally occurring isotopes to explore questions such as origin of the deep-source Hawaiian plume and other hotspots. Applications of this research also include tracing contaminants, understanding life cycles of volcanoes and isotopic evidence that may lead to detecting life on other planets.

Susan S. Hubbard

environmental engineer / geologist

Susan’s research focuses on advancing the use of geophysical methods for shallow subsurface characterization and monitoring and the use of integrated datasets to investigate environmental problems. In 2013 she was named Director of the Lab's Earth Sciences Division.

Burton M. (Mack) Kennedy

geochemist

Mack Kennedy is applies isotope techniques to further our understanding of the origin, history, and current processes acting on the earth and solar system.  Research areas include geothermal energy, fossil energy, and basic energy sciences.

Ernie Majer

geophysicist

Ernie Majer's research focuses on utilizing geophysical methods for recovery of conventional and alternative energy sources, environmental cleanup, nuclear waste disposal and CO2 sequestration.

Gregory Newman

geophysicist

Gregory Newman's research focuses on large-scale, multi-dimensional, inverse and forward modeling problems arising in exploration geophysics, parallel computation and electromagnetic geophysics.

Margaret S. Torn

ecologist and biogeochemist

Margaret Torn studies climate change impacts on ecosystems and the services they provide to society.  Her work focuses on the influence of the land surface on climate, including the potential for ecosystem-climate feedbacks to contribute to abrupt climate change.
