My study reports on a case study of a Spanish native speaker’s academic writing in
English regarding his identity expression. I use Ivanic’s (1998) framework on
writer’s ‘discoursal identity’. I also included the writer’s mini-autobiography and a
semi-structured Skype-interview for an in-depth analysis of the writer’s authorial
representation and autobiographical self. This triangulation of data shed light on the writer’s identity construction. I therefore also reflect on the use of a case study
approach when analysing a writer’s ‘identity construction’.
