معرفی
Nathaniel R Miller is the Laser Ablation and ICP-MS Lab Manager and a Lecturer in the Department of Earth and Planetary Sciences at the Jackson School of Geosciences, The University of Texas at Austin. He specializes in trace element and isotopic analysis using advanced mass spectrometry techniques.
His professional background includes over two decades of teaching Earth Science courses and prior industry experience in hydrocarbon exploration and reservoir characterization with ARCO/Mobil. He currently teaches advanced courses on inorganic mass spectrometry (GEO 391, 390S).
Research Interests:
Miller focuses on sedimentary geochemistry, global change dynamics, and their applications to modern and ancient depositional environments. Key areas include chronostratigraphy, carbonate geochemistry, microbial dolomite formation, high-resolution chemostratigraphy in speleothems and microbialites, and isotopic tracing in systems like the Red River. He employs geochemical, isotopic (C, O, S, Sr), GIS, and field-based methodologies.
Lab and Collaborations:
He oversees the Quadrupole ICP-MS Lab, which supports trace element analysis, 2D chemical mapping (e.g., fish otoliths, stalagmites, carbonate cements), and innovative techniques such as matrix-matched M/Ca ratio determination in carbonate biominerals. The lab emphasizes collaboration and offers analytical services for diverse sample types.
