The Selkin lab group in the Sciences and Mathematics Division at UW Tacoma explores the geological history of the deep and surface Earth using magnetism and other geophysical techniques. The focus of much of our work is on understanding transport processes in sedimentary and magmatic systems. Our research projects have criscrossed the geologic time scale, from investigating magnetic materials in recent (human-made) smelter dust to analyzing magnetic records of crystallization in a 2.7 billion-year-old magma chamber. We have active research projects in the areas listed here.
