Medicine lecturers are subject professors, teachers, or lecturers, and often doctors who instruct students who have obtained an upper secondary education diploma in their own specialised field of study, medicine, which is predominantly academic in nature. They work with their university research assistants and university teaching assistants for the preparation of lectures and of exams, for grading papers and exams, for leading laboratory practices, and for leading review and feedback sessions for the students. They also conduct academic research in their respective field of medicine, publish their findings and liaise with other university colleagues.
