This is a $1,953,008 grant awarded by the National Aeronautics and Space Administration (NASA) to Arizona State University (ASU) to conduct research on the early history of the solar system. The objective is to better understand processes in the solar nebula and on planetesimals through investigations of radiogenic isotope systematics, stable isotope systematics, and trace element geochemistry of primitive and differentiated meteorites. The research addresses NASA's Emerging Worlds program goals...
This $704,133 NASA grant was awarded to Arizona State University (ASU) to conduct research related to the global redox state of the mid-Proterozoic oceans and its relationship to the evolution of early eukaryotes. The research aims to refine the use of uranium isotopes as a proxy to better constrain oxygen levels during this critical period in Earth's history. The work involves experimental studies, analysis of modern analogue environments, and integration with ASU's existing dataset on...
This is a $358,750.01 grant awarded by the National Aeronautics and Space Administration (NASA) to Arizona State University for research on the chemical mechanism responsible for the mass-independent fractionation of sulfur isotopes seen in Archean sedimentary rocks.

This is a $114,846.10 training grant awarded by the National Aeronautics and Space Administration (NASA) Shared Services Center to Arizona State University (ASU) to study the role of oxidative weathering in the Great Oxidation Event, a key event in the oxygenation of Earth's atmosphere. The grant supports experiments to measure the kinetics of oxygen consumption by various rock types at low oxygen levels relevant to the Archean eon, prior to the oxygenation of the atmosphere. The goal is to...
This is a $298,433.31 research grant awarded by the National Aeronautics and Space Administration (NASA) to Arizona State University (ASU) to conduct a study on nanoprecipitates within meteoritic metals as tracers of early solar system processes. The proposed research aims to use transmission electron microscopy (TEM) and micro-particle-induced X-ray emission (micro-PIXE) techniques to characterize the nanoscale phase petrology of metal systems in iron meteorites and metal-rich breccias. This...
Arizona State University was awarded a $374,620.96 grant from the National Aeronautics and Space Administration (NASA) to conduct research related to oxygen isotope fractionation and self-shielding in the solar nebula. The research aims to improve understanding of how carbon monoxide (CO) self-shielding can explain enrichment of oxygen-17 and oxygen-18 in terrestrial planets and meteorites compared to the solar photosphere. The grant involves analyzing high-quality ultraviolet absorption cross-section data for CO isotopologues, measuring quantum yields, developing coupled-channel models, and integrating the results into solar nebula models. No set-aside designation was indicated. This research builds on previous NASA-funded efforts and involves collaborations with researchers in the U.S. and France.
