Language production, psycholinguistics, cross-linguistic analysis, and cognition in general are my primary interests. Current work ranges from basic processes of word production, especially the roles of sublexical units, to sentence level planning and the conceptual-lexical interface. Recent collaborations include studies of the productive phonology of Mandarin Chinese and of Spanish, Chinese speakers' conception of time, and dynamic processes in concept-to-word mappings.
