Civil and Environmental Engineering
In relation to global change, Dr. Pruden studies the role of microbial communities in dynamic environmental systems. For example, there is currently a boom in the manufacture of nanomaterials, and therefore a need to understand the implications of these new products in terms of biodegradability by and toxicity to microbes in wastewater treatment plants. Similarly, efforts to conserve water and energy result in new “green” building designs that impose atypical water flow regimes in pipes. This will shift the kinds of microbes that reside there and the potential for pathogens to establish. A third example: how will changes in antibiotic use guidelines for livestock impact the actual attenuation of antibiotic resistant bacteria and the antibiotic resistance genes that they carry?
At Virginia Tech, Dr. Pruden teaches CEE 5194 Environmental Engineering Microbiology and an IGEP Course on Interdisciplinary Research, GRAD 5134. She is a core faculty member in three interdisciplinary graduate education programs, Water for Health, Sustainable Nanotechnology, and Interfaces of Global Change.
