Interface between Corpus linguistics & Theoretical Linguistics
Perhaps, for many modern theoretical linguists, E-languages are 'amorphous' and are too marginal an issue to examine.
But, at the same time, it is only through the investigation of E-languages which we understand the I-language. Without a robust methodological reflection on E-languages, we could not perfectly understand the nature of the language.
One of my research topic is to cross a bridge between the tradition of theoretical linguistics and a data analysis of E-languages.
Once linguistic expressions are quantified and are represented as a vector, we will inevitably discuss their distribution in higher dimensions. If you are also interested in learning the nature of the manifold, or if you are curious about the geometrical understanding of their distribution, let us start a new joint-project!

Dynamic Pragmatics
Selected papers
Interface between Dynamic Pragmatics & Statistics
If the discourse is consistent, the information state shrinks in a monotonic way as the conversation goes ... yes, such an idea is quite useful in modeling the informative component (and the inquisitive aspect) of the context. But ... does the same idea apply to other aspects of the context change?
In order to capture the expressive dimension of the discourse, I have been proposing that we should incorporate a statistical structure. Especially, Bayesian approaches seem to provide us fruitful insights both in practice and in our understanding of natural language inferences. One of my on-going project is to extend this view to cross a bridge between well-established formal semantic and pragmatic approaches and mathematical theories.

Project 3 Syntax-phonology Interface
Interface between Morpho-Phonology & Syntax
How does the syntax interact with morpho-phonology? In the mainstream Minimalist Program, it has been assumed that "Syntax is Syntax" and "Phonology is Phonology."
But there are some data that seem to suggest that phonological operations precede some syntactic operations. If so, what would be the best architecture for the syntax, morphology and phonology? Based on some prosodic data in Japanese, I have been proposing a model in which the strict division of labor is loosened between the (narrow) syntax and the phonology.
