The central algorithmic problem in coding theory is the construction of explicit error-correcting codes with good parameters together with fast algorithms for encoding a message and decoding a noisy received word into the correct message. Over the last decade, significant new developments have taken place on this problem using graph-based/combinatorial constructions that exploit the power of <i>expander graphs</i>. The role of expander graphs in theoretical computer science is by now certainly well-appreciated. Here, we will survey some of the highlights of the use of expanders in constructions of error-correcting codes.
