Margaret Riley studies the processes and patterns of microbial ecology and evolution. Her research interests range from studies of experimental evolution of microbes to developing novel antimicrobials and redefining the microbial species concept. A focus of her work is determining the origin and evolution of resistance mechanisms in natural isolates of bacteria that can be used in efforts to design more “resistible” antibiotics and to predict future pathways of resistance evolution.
