Lecturer is the name given to universityteachers in most of the English-speaking world (but not at most universities in the US or Canada) who do not hold a professorship.
United Kingdom
Lecturers are generally divided into Lecturers, Senior Lecturers, and Principal Lecturers/Readers and are permanent positions in a university which involve carrying out both teaching and research. These positions are generally comparable to "Assistant", "Associate", and "Full" Professors, respectively, under the US system, with the title "Professor" being reserved for only the most senior academics in the UK, and roughly equivalent to a chaired professorship in the US. Most lecturers have Ph.D.s, and in many fields this is a pre-requisite of the job.
United States
Some American universities have Lecturers whose responsibility is undergraduate education, especially for introductory courses that attract hordes of students. These lecturers generally do not have research duties, and the position is sometimes regarded as less prestigious than a professorship. It may not require a doctoral degree, depending on the university (see the article, "professor")
Lecturer is the name given to universityteachers in most of the English-speaking world (but not at most universities in the US or Canada) who do not hold a professorship.
Lecturers are generally divided into Lecturers, SeniorLecturers, and Principal Lecturers/Readers and are permanent positions in a university which involve carrying out both teaching and research.
Hence Senior Lecturer/Reader are essentially the same rank with the former position having a higher emphasis on teaching and the latter position having a higher emphasis on research at some institutions.
Seniorlecturers shall be appointed annually (or for a longer period with the approval of the Vice President for Academic Affairs) at a salary appropriate for their qualifications, responsibilities and department.
Lecturers fulfilling these criteria may be nominated for the position of seniorlecturer by their department chair, or a faculty member or seniorlecturer in their department.
Lecturers and seniorlecturers are all strongly encouraged to attend college meetings and to participate in the discussions.
