Scientists in the courtroom: Basic pointers for the expert scientific witness

Abstract

The need for expert and unbiased participation in legal proceedings by physicians, industrial hygienists, toxicologists, environmental scientists, regulators, and similar professionals is hampered by lack of familiarity with the requirements of expert testimony and lack of opportunities for professional training in this activity. Drawing on material developed in a continuing education course offered by the University of Washington, we describe the role and process of being an expert witness and provide basic information regarding good professional practices pertaining to the testifying expert role.
