The work involves responsibility for performing the more technical and complex procedures required in scientific analysis of physical evidence which may include the chemical analysis and identification of drugs and trace evidence. An employee in this class sets up, operates and maintains a variety of scientific instruments in performing chemical analyses. Under the technical supervision of a more senior technical member of the Center for Forensic Science staff, with administrative direction from the Director of Laboratories, an employee in this class is responsible for providing guidance to less experienced forensic chemists including training in methodology and procedures and for technical review of analysis. An employee in this class typically reduces conclusions and findings to writing in the form of reports and appears as an expert witness during litigation. General supervision is received from the Senior Forensic Chemist (Criminalistics). Does related work as required.
