The aerodynamic response of airborne discs
A study has been conducted to characterize the flow over a free-flying disc. In this study, three types of discs are analyzed in a series of stationary experiments, and a single disc is analyzed in a spinning experiment. Two dimensionless parameters dominate the experiments, the Reynolds number and …

Airborne Dissemination of Antibiotic Resistance Genes Near Farms and Effectiveness of Ionization Against Airborne Bacteria in a Classroom
The Covid-19 pandemic heightened attention to airborne microorganisms and their widespread impacts. This dissertation examines two facets about airborne microorganisms: (1) dissemination of antimicrobial resistance in the environment and (2) ionization for disinfection of indoor air. Antimicrobial …
