Implementation, context and complexity and the study of introducing health care innovations.

An important part of Professor May’s work over the past two decades has been the development of middle-range theoretical models that identify, characterise and explain the mechanisms that motivate and shape implementation processes (Normalisation Process Theory). Building on this, Professor May has developed theoretical models of the ways that socio-technical transformations and policy restructuring in healthcare systems affect patients and caregivers (Burden of Treatment Theory).
