The University of Aberdeen has a long-established international reputation for excellence in theological research, publication and teaching, and a flourishing community of graduate students from the UK and overseas.

Systematic Theology in Aberdeen

Systematic theology is a major research concentration. The department has one of the largest groups of post-graduate research students in the field in the UK, attracted by the publications of its teachers and by its positive ethos; many students come to study topics in constructive Christian doctrine or the theologies of classical and modern Christian thinkers. Students can expect rigorous training in the history and contemporary articulation of Christian doctrine through attentive supervision and an extensive programme of seminars. 

There are close working relations with those undertaking research in other theological fields, especially moral, philosophical and practical theology, the history of Christianity, and the study of Scripture.


We are interested in hearing from students wishing to undertake postgraduate level work on Systematic Theology at the doctoral level. Please contact one of the supervisors below if you are thinking about applying for a PhD in their subject area.
