My work explores the constraints on microbial niche breadth and the extent to which niche breadth can be modified by new environmental pressures. This research has fundamental implications for microbial biogeography, as well as the fitness and functional costs of different types of generalism. It also has numerous applications, including microbial product development, the limits of directed evolution for biotechnology, and the detection and management of microbial invasions.
