The paper develops an SIS model for multi-strain epidemics with co-infection on host contact networks, showing that network heterogeneity increases dynamics speed and stabilizes strain coexistence.

The paper develops a spatial SIS model with coinfection and multiple strains to study how spatial structure and host movement affect pathogen dynamics in heterogeneous environments.

The paper develops a framework to quantify fitness differences between two co-invading strains using the replicator equation and applies it to antibiotic-resistant E. coli in the gut microbiota.

The paper infers pairwise bacterial strain interactions from population frequency data across multiple settings using a replicator dynamics framework applied to Streptococcus pneumoniae serotypes.
