Traditionally, the trees studied in infinite graphs are trees of height at most omega, with each node adjacent to its parent and its children (and every tree branch inducing a path or a ray). However, it  has become apparent over the previous decade that the structure of infinite graphs is in fact much more closely governed by the theory of well-founded order trees. In this talk, I will describe these connections and discuss some of the key results in the field.
