Loewen, Matthew

Matt has worked as a Research Geologist for the U.S. Geological Survey working at the Alaska Volcano Observatory in Anchorage, AK, since 2017. His research utilizes igneous petrology, geochemistry, field mapping, stratigraphy, physical volcanology, and remote sensing techniques to study the geologic history and magmatic system of Alaska volcanoes.
