Allison G. Caster

Teaching Associate Professor, Department of Chemistry

Allison CasterAllison Caster joined Mines as a Teaching Assistant Professor of Chemistry. Allison earned her BS in Chemistry at the University of South Dakota (2004), and her Ph.D. in 2010 from the University of California – Berkeley, where she was a National Science Foundation Graduate Research Fellow. This was followed by a Postdoctoral Fellowship at the University of Colorado Anschutz Medical Campus in Bioengineering. Allison has developed non-invasive, laser and X-ray based microscopy techniques for probing the chemistry of both natural and man-made structures. The applications of these techniques are, for example, to improve the production of smaller integrated circuits, or to identify and sort cancerous from non-cancerous cells in human blood. With a shift in focus to undergraduate eduction, Allison strives to highlight the applications of modern, interdisciplinary research in the classroom and laboratory, and to implement more active-learning strategies which improve student engagement, excitement, and retention.
