The Erdős-Rogers function measures how large a K_s-free induced subgraph there must be in a K_t-free graph on n vertices. Good estimates are known when t=s+1, but in general there are significant gaps between the best known lower and upper bounds. We have improved the best known upper bound for s+2<=t<=2s-1. In this talk, I shall describe the construction, and sketch the proof that it has the required properties. This is joint work with Tim Gowers
