I am interested in broad aspects of igneous petrology, the earliest history of our planet, and how these processes relate to other Earth systems. Below are examples of research directions that I am currently pursuing.
The main thrust of my research has been, and will continue to be using integrated petrology, isotope geochemistry, and new mass spectrometry techniques to answer fundamental questions about when and how the continental crust formed, with emphasis on the early Earth.
Ultimately, I am interested in developing projects and collaborations in the areas listed below as well as any other areas. If you have questions, comments, or other ideas please get in touch!
1) Understanding the formation and uplift of ancient continents using the rock and mineral record, with a focus on the Meso-NeoArchean transition (~2.8 Ga)
2) Developing a novel type of mass spectrometer for high precision isotopic analyses of terrestrial and extraterrestrial samples
3) Enhancing the petrologic interpretations of the zircon record and developing new techniques for utilizing zircon trace-element and isotopic datasets. These projects are focused on developing novel approaches, both analytically and statistically, to elucidate magmatic processes throughout Earth history
4) Development of new geochronological tools for understanding fluid flow in sedimentary basins.
