Earth Evolution

Samantha Stevenson

My research goals relate to understanding how large-scale climate variability responds to changes in climate, how we can improve our inferences of those changes using paleoclimate archives, and using that information to improve the representation of climate variability in climate models.

My research covers several aspects of structural seismology, with a focus on answering fundamental questions about tectonic processes using seismic tools. I have worked on research projects in Papua New Guinea, Iceland, Greece, Cascadia, and Ethiopia. My primary areas of expertise are seismic tomography, anisotropy, and attenuation.

Stanley Awramik

My research interests center on understanding the early history of life on Earth. The major focus is on the fossil record during the Archean and Proterozoic, specifically on microbial fossils and stromatolites.

Roberta Rudnick

My research focuses on the origin and evolution of the continents, including the continental lithospheric mantle. Emphasis is placed on integration of data from a wide diversity of sources, including petrography, petrology, major and trace element geochemistry, isotope geochemistry, and geophysics in order to determine the bulk crust composition of the crust, the processes that have influenced its composition through time and why the Earth has continents. I have also been investigating the lithium isotope system as a tool for tracing fluid flow, continental weathering and crustal recycling.

Phil Gans

My interests lie in the general fields of structural geology and tectonics and are focused on deformational and thermal processes within the continental lithosphere. My research is mainly in the field of Extensional Tectonics and is focused on exactly how continents rift and the relationship between extension and magmatism. I make most of my observations and draw much of my scientific inspiration from field-based investigations.

Understanding Quaternary climate change, geomorphic processes, landscape evolution, and tectonic processes through integrated studies involving cosmogenic radionuclide dating, recent and past climatic records, remote sensing, numerical modeling, and field observations

Matthew Jackson

Professor Jackson uses the isotopic and chemical composition of lavas erupted at plume-fed hotspot volcanoes to gain insight into the make-up of the Earth’s deep interior. In particular, he is interested in understanding the origins (recycling of subducted material, metasomatism, etc) and length scales (hemispheric to micron-scale) of heterogeneities in the mantle. He employs innovative in situ techniques to get at the composition of lavas, phenocrysts and the melt inclusions they host.
