The theory of expander graphs has seen increased interaction between mathematics and computer science in the last 50 years with a high dimensional theory emerging in recent years that has shown unexpected applications in both areas.

In October 2019 the Simons Foundation held a first-of-its-kind meeting on high dimensional expanders, which promoted more interest and interaction around this subject. This current workshop will again bring mathematicians and computer scientists, with a wide range of interests, to report and hear about the developments over the last two years and to discuss future directions of research.
