Dr. Niemi is a Quaternary geologist who specializes in geoarchaeology, sedimentology, and active tectonics. Her interests include studying active faults, earthquake recurrence in the geologic and archaeological records, paleoenvironmental reconstructions, analyses of high-resolution geophysical data, and characterization of recent hurricane and tsunami deposits. As a field geologist, she and her students collect aerial imagery using drones and stratigraphic data from outcrops, trench excavations, and cores in order to build a deeper understanding of the history and nature of tectonic, climatic, and anthropogenic environmental change through time. Students under Dr. Niemi’s supervision have done research in México, Guatemala, The Bahamas, India, Jordan, Turkey, and on the San Andreas fault and New Madrid Seismic zone.
