Biographical details

David Hamer's primary research interest is in the law of evidence. He takes an interdisciplinary approach, interrogating the law - and the proof process more broadly - using tools drawn from probability theory, narrative theory and psychology. His interest in evidence law often flows over into areas of substantive law and broader issues, in particular law's continuing struggle with the notion of causation, criminal justice, and the causes of and solutions to wrongful convictions.
