Richard Kettler

Richard Kettler serves as Associate Professor in the Department of Earth and Atmospheric Sciences at the University of Nebraska-Lincoln, where his research integrates laboratory geochemistry with field studies of diagenetic processes. His work bridges fundamental thermodynamic measurements and applied investigations into ore-forming systems, meteorite parent bodies, and potential origins of life.

Research Interests

Professor Kettler's primary focus involves the geochemistry of polyfunctional carboxylic acids and Fe-C-S systems in geological materials. His investigations span:

• Thermodynamic properties of organic acids for geochemical modeling
• Biogeochemistry of thermoacidophilic microbes in extreme environments
• Sedimentary diagenesis and ocean chemistry controls on ore deposits
• Siderite oxidation mechanisms in Navajo Sandstone concretions
• Carbonatite petrogenesis and rare earth element mineralization

His recent publications emphasize microbial roles in iron mineralization and the application of iron isotopes to decipher diagenetic pathways.

Publication Trends

Kettler's scholarly output reveals an evolution from laboratory-based organic acid thermodynamics (1990s-2000s) to integrated field-laboratory studies of diagenetic systems. Current work (2020-2024) centers on siderite oxidation hypotheses, fracture-controlled fluid flow, and Liesegang phenomena in iron oxide mineralization, while maintaining connections to planetary science through meteorite parent body chemistry. His 2021 DEI publication indicates expanding contributions to geoscience education.

Academic Contributions

Professor Kettler mentors students from geology, chemistry, and biological sciences backgrounds who have successfully advanced in academic and industry careers. His departmental involvement includes leadership in the UNL URGE Pod for diversity initiatives. While specific grant details aren't provided, his sustained publication record across five decades suggests consistent research funding in geochemical and sedimentological investigations.
