Ellie's voice actress' name is Ashley Johnson. As far as live action roles go, I'd say she's most recently known for her work with Joss Whedon films, including The Avengers:

and Chrissy Seaver from Growing Pains:
But here's the most interesting bit for me: she also played this girl:
Gretchen Grundler, from Recess.
