Stability can be defined as how well the community handles change. Stable communities are able to resist a change in the nutrient supply or an invasion of a new species. Less stable communities are prone to change in the face of these disruptions.

Sergei Maslov, a Bliss Faculty Scholar, professor of bioengineering, and a faculty member in the Biocomplexity theme at the Carl R. Woese Institute for Genomic Biology, and Akshit Goyal, a visiting scholar from the Simons Centre for the Study of Living Machines at NCBS, in Bengaluru, India, have previously collaborated on a predictive model to measure microbial community stability based on an economic concept called the "stable marriage problem" as published in The ISME Journal. They recently created a mathematical model to further understand how microbial communities function and maintain stability.
