Instructor: Alicia McCarthy

Course length: 4 hours

The role of the forensic scientist in the criminal justice system is a varied one.  We are asked to process crime scenes, teach evidence collection techniques to non-scientists, analyze evidence in the laboratory, and issue reports on our findings. 

One of the most important roles of a forensic scientist is to effectively communicate scientific findings in layperson's terms to police officers, lawyers, judges, and juries.  The most challenging form of communication is often the process of testifying as an expert witness in court.  This communication process is not straight forward as information the expert witness needs to communicate to the court comes through questions asked by the prosecution and defense attorneys, and the communication is one-sided because the jury (usually) can’t ask questions of the expert.

The skills taught in the Expert Witness Testimony webinar are based on empirical research around jurors' understanding of expert witness testimony.  The participants will gain a real world understanding of the current best practices for communicating forensic science conclusions and opinions to judges and juries.
