Curriculum Vitae

My areas of specialization include cognitive linguistics, semiotics, discourse analysis, and rhetoric. These areas of specialization provide the frameworks and methods for tracing the micro-cognitive and phenomenological bases of attention as they make their presence felt in the higher-order activities of social awareness, discourse, and persuasion. Human minds are "rhetoric machines."
