He joined the British Council and worked for twenty years as an English Language Officer in Iran, Singapore and London. From 1990 to 2000 he worked as a Senior Lecturer at the Centre for English Language Studies, at Birmingham University, working mainly on MA TEFL/TESOL programmes.

He has published widely on discourse analysis, the subject of his PhD thesis at Birmingham, on the description of grammar and lexis for ELT, and on task-based methodology.
