I'm interested in how conceptual structure (such as metaphor, metonymy, mental spaces, and category structure) is communicated using language. I believe that in order to understand how conceptual processes are expressed, we need a theory of grammar that recognizes constructional meaning, such as Construction Grammar; a better understanding of how conceptual structures surface in gesture, in artwork, and across various genres of language use; and a model of semantic change that integrates metaphoric extension and inference-based extension.
