The work involves the use and routine maintenance of sophisticated modern laboratory equipment. The incumbent may oversee and review the work of subordinate laboratory personnel, ensure the reliability of test results, and develop and evaluate methods used in the section. May participate in crime scene investigations and issue reports of analyses performed. The work includes giving testimony at a variety of legal proceedings, and requires the exercise of independent judgment and initiative.
