Tom Roeper gave two talks in Germany a couple weeks ago. He presented joint work with Jill de Villiers at a conference on Recursion, Complexity and Typology at Konstanz. The title of their talk was "Avoid Phase: wh-infinitives and movement in acquisition." And he gave a paper titled "Internal Merge vs Topic Shift in Acquisition" at the ZAS conference on Discourse Cohesion in Berlin.
Congratulations Tom!
