Caltech Noble Gas Lab: Personnel

SFT

Ken Farley

Professor

I am the W.M. Keck Foundation Professor of Geochemistry and the chair of the Department of Geological and Planetary Sciences at Caltech. I have conducted research on a range of problems involving noble gas geochemistry during my career. I am currently a Participating Scientist on the Mars Science Laboratory mission.

Peter Martin

Graduate student

My background is in Martian geochemistry and I am working on both radiogenic and stable isotope data coming back from the SAM instrument on the Curiosity rover. I also work on Mars analogue environments on Earth, looking at relative age relationships in weathered arid environments and examining potential age dating applications in planetary settings.

Florian Hofmann

Graduate Student

My research is in helium geochronology of iron-oxides. I'm combining measurements of (U-Th)/He formation age and cosmogenic 3He to study goethite pisoliths of the Bohnerz Formation in Germany and Switzerland. I'm also working on extending these techniques to fine-grained iron-oxides in soils and paleosols. More information is available on my research website.

Stephen Cox

Graduate student

My background is in helium thermochronometry and argon geochronometry. I studied at Columbia University as an undergraduate and worked in the AGES lab. At Caltech, I have continued to work on helium dating while also pursuing the (U-Th)/Ne and cosmogenic neon chronometers and the heavy noble gases krypton and xenon. More information about these systems is available on my personal website.

Hayden Miller

Graduate student

I study the interaction of climate and tectonics over geologic timescales using helium and neon thermochronometry and stable oxygen isotopes of iron oxides. My work includes applying 4He/3He thermochrometry, and (U/Th)-He and (U/Th)-Ne chronometers in hematite; the development of ‘intracrystalline thermometry' in goethite; and studying continent scale climatic changes through traditional stable oxygen isotope measurements and (U/Th)-He ages of goethites.

Forrest Horton

Post-doctoral research scientist

I am developing new methods for analyzing noble gases in volcanic rocks which will improve our ability to characterize the deepest parts of Earth's mantle. My research interests also include high temperature processes in continental crust and the flux of biologic nutrients from flood basalts to the oceans. More information is available on my personal website.
