Keith Morrison, a SESE doctoral student, received an ARCS scholarship (second year) for his work on antibacterial clays. His work was highlighted on the ARCS National website.
He published a paper in the November 2013 journal of Environmental Geochemistry and Health on antibacterial clay research. The article was titled “Mineralogical Variables that Control the Antibacterial Effectiveness of a Natural Clay Deposit.” Morrison is concerned with the health risks due to the rise of antibiotic-resistant bacterial strains. He is researching finding alternatives to conventional antimicrobials. His paper focused on an antibacterial clay deposit near Crater Lake, Oregon.
