Tom Ling heads up the evaluation team at RAND Europe, based in Cambridge. His research is focused on multi-faceted and sometimes complex interventions. Much of this is on health interventions where current work includes studies of integrated care, clinician engagement in quality improvement, and the interconnections linking research with practice. These are frequently and necessarily interdisciplinary. He is also interested in how evaluative evidence is (or is not) used to support learning and accountability. On a related issue he is interested in scenario thinking in supporting both strategy and evaluation.
