Senior lecturer is an academic rank. In the United Kingdom and Australia, lecturer is a faculty position at a university or similar institution. Especially in research-intensive universities, lecturers lead research groups and supervise research students, as well as teach. After a number of years, lecturers might be promoted to senior lecturers with increasing research, leadership, and administrative responsibilities. A senior lecturer position is between a lecturer and a reader.
However, in the United States, Canada, and other countries influenced by their educational systems, the term is used differently, generally denoting academics without tenure who teach full or part time but have few or no research responsibilities.
