This paper sets out to show how some theoretical concepts derived from Lacanian psychoanalysis might be put to work in the business of reflective practitioner research in education. It seeks to offer a more sophisticated, reflexively produced account of researcher identity built out of the narrative generated within a research enquiry. It illustrates, with reference to examples of writing from a specific research project, carried out within the context of a higher degree, how one teacher-researcher has used the concepts in forging a more productive understanding of her own evolving identity as a researcher through a process predicated on developing her own professional functioning. Shifting perspectives are provided on what the researcher wants from the enquiry as the researcher herself unfolds and analyses the successive phases of her narrative.
