CV Singer June 2021

My research uses high-precision geochronology to resolve fundamental geoscientific problems, mainly in three areas: (1) linking the long-term evolution of volcanoes to current states of activity and unrest, (2) the history of the earth’s magnetic field and geodynamo, and (3) chronostratigraphy and evolution of sedimentary basins. The WiscAr Geochronology Laboratory is sought out by researchers and students both within our Department and from outside of the University of Wisconsin-Madison to address volcanic, igneous, tectonic, and sedimentary processes.

I am leading an international team to explore the impact of ice forcing on arc magma plumbing systems during the next 5 years.  This project will collect new data and develop numerical models of how the rapid loss of the Patagonian Ice Sheet affected the composition and rates of eruptions at 6 volcanoes in the Southern Andes of Chile.
