Dr. Fisher develops, evaluates, and applies technologies and methods for addressing under-recognized health concerns in water and sanitation, both in the US and internationally. This work focuses on three areas: 1) monitoring and evaluation of water and sanitation processes, infrastructure, and service delivery; 2) improving water and wastewater treatment; and 3) applications of implementation science and quality improvement methods to improving the performance of water and sanitation systems. Topics of particular interest within these areas include improving the monitoring and control of antimicrobial resistant (AMR) organisms, as well as pathogens (such as some protozoan cysts and enteric viruses) that are resistant to conventional disinfection methods, in water and wastewater. Overall, this research contributes to a greater understanding of the determinants of effective and beneficial water and sanitation service delivery, and to innovations and evidence that can be used to improve these services.
