Prof Tom Marshall, CLAHRC WM Co-Director, will be giving his inaugural lecture on Wednesday 2 March, 16:30-17:30, at the Leonard Deacon Lecture Theatre, University of Birmingham – 'The Knowable and the

Unknowable: Reflections on Health Services Research'. A fundamental difference exists between clinical practice and science. Clinicians diagnose, make prognosis and decide on treatment, generating apparent certainty from uncertain symptoms and situations. But science is driven by doubt. In this lecture, Professor Marshall will explore some of the paradoxes of knowledge and its absence in relation to his own research.
