Hans Broekhuis has worked as a researcher and assistant professor at the University of Amsterdam, the University of Tilburg, University Leiden and, currently, the Meertens Institute in Amsterdam. His theoretical work is mainly conducted within the principles-and-parameters framework.

He mainly works within the framework of generative grammar, focusing on syntax and its interfaces with semantics and phonology, and their modeling within optimality theory. More recent work is dealing with the syntax-prosody interface and with the integration of advanced methods of empirical linguistic research with grammatical theory. He is co-editor of Minimality Effects in Syntax (with Artur Stepanov and Gisbert Fanselow, Mouton de Gruyter, 2004) and Gradience in Grammar: Generative Perspectives (with Gisbert Fanselow, Caroline Fery and Matthias Schlesewsky, Oxford University Press, 2006).
