Abstract: After surveying the problem of computing the zeta function and l-adic coho- mology of Shimura varieties in the context of the Langlands program, I will report on joint work with Mark Kisin and Yihang Zhu to establish a stabilized trace formula computing the cohomology of abelian-type Shimura varieties at primes of good reduction, building upon earlier work by Kisin.
