Abstract：

Since its invention by Grothendieck in the early60's etale cohomology has undergone a fantastic development and its applications to algebraic geometry and number theory are innumerable. Some challenging problems posed at the beginning are still actively studied today. I will report on some recent progress made in several directions. I will mainly focus on Gabber's finiteness and uniformization theorems for quasi-excellent schemes, solving foundational questions raised in Grothendieck's seminars SGA 4 and 5.
