Research

My students, postdocs, collaborators and I study natural and anthropogenic processes that are important to the evolution of our planet and that impact the health and sustainability of our communities. We use geophysical methods (usually magnetic techniques) in combination with field observations and microscopy to explore processes that operate on global, tectonic, outcrop, and nanometer scales. Our research has uncovered new discoveries about the behavior of the Earth’s magnetic field, tracked environmental change through time, compiled paleoflood histories from speleothems, monitored groundwater quality in the Twin Cities, and characterized novel magnetic materials. Please explore the examples below!
