Research Interests

Empirical Foundations of Syntax

I have started the Spoken Syntax Laboratory at CSLI to provide resources for collaborative work on syntax using multiple sources of evidence and modern statistical models.

Linguistic Typology

I am interested in theoretical models of typological variation of languages. I have served as an Associate Editor of the journal Linguistic Typology.

Dynamics of Probabilistic Grammar

I am working with other linguists, psychologists, and computer scientists to develop and test probabilistic models of how grammar varies in the individual and in speaker groups across space and time.

Lexical-Functional Grammar

I am one of the original designers and developers of LFG, the formal grammar system which allows flexible, typologically diverse linguistic description and has been embedded in explicit theoretical models of exemplar-based syntax, optimality-theoretic syntax, and stochastic grammar.
