This includes novel strategies of improving patient room cleaning and disinfection, including human factors engineering approaches, and conducting robust clinical trials to examine effectiveness of “no touch” novel technologies such as UV-C light. She has particular interest in carbapenem-resistant Enterobacteriaceae transmission in the hospital environment, including outbreak management, and transmission and epidemiology of Clostridium difficile. Her other area of interest is diagnostic stewardship, and the behavioral, cultural and human factors aspects of implementation of initiatives to enhance appropriate use of diagnostic tests. She leads a national initiative, as part of the High Value Practice Academic Alliance, examining strategies for appropriate testing for Clostridium difficile.
