Dr. Alan Rooney [assistant professor]
I am interested in understanding the interactions between tectonics, climatic processes and geochemical cycles on a range of time scales. I use radiogenic isotope geochemistry, in particular the rhenium-osmium (Re- Os) geochronometer, Sr and Nd isotopes combined with field-based mapping, sedimentology, stratigraphy and mineralogy to interrogate the rock record of critical transitions in Earth history.

Dr. Tim Gibson [Post-doc]
I am broadly interested in reconstructing Earth history from its sedimentary record. Specifically, my research aims to decipher how interactions between the geosphere and biosphere regulated the Proterozoic environment from 1.2 to 0.8 billion years ago. I am currently investigating various sedimentary basins in Svalbard, arctic Canada, and Greenland through the lens of geobiology. This means that I implement a combination of sedimentology and stratigraphy, hydrocarbon biomarker, stable and radiogenic isotope geochemistry, and geochronology to reveal the geochemical and evolutionary landscape leading up to many pivotal climatic, tectonic, and evolutionary events.

Erica Evans [graduate student]
My research focuses on understanding the connections between glaciations, weathering substrate composition and global climate. Currently, I am using the Re-Os geochronometer, osmium and neodyumium chemostratigraphy to investigate perturbations in weathering in the Ordovician and Pleistocene.

Sierra Anseeuw [Lab Manager]
I manage day-to-day lab operations in the Rooney Lab. I recieved my BS in Environmental Geology from Beloit College and my MS in Geology from University at Buffalo. My research background is in isotope geochemistry and contaminant hydrogeology

Gone but not forgotten:
Dr. Anne Bauer [Faculty at U Wisconsin]
My research focuses on the geochemical record and tempo of atmospheric and oceanic oxygenation, Hadean and Archean crustal production and preservation, and analytical technique development in radiogenic and stable isotope geoscience. With new projects I am applying the Re-Os geochronometer to refine temporal constraints and evaluate the nature of continental weathering during the Paleoproterozoic Lomagundi-Jatuli carbon isotope excursion.
