Answer:
Expert witness
Explanation:
Forensic expert testimony would be testimony grounded within and concerning the field of forensic science, which, in turn, is a branch of science which is specifically designed to assist with answering important questions that might arise within a given trial. A forensic expert witness thus might be a specialist in any of a number of fields of forensic science, including forensic anthropology, forensic archaeology, forensic chemistry, forensic dactyloscopy, and forensic computer science.
