Core Responsibilities

Primary Functions

Conduct complex qualitative and quantitative chemical analyses on physical evidence, including suspected controlled substances, pharmaceuticals, and unknown chemicals, using established scientific protocols.
Perform detailed analysis of trace evidence such as paint chips, glass fragments, gunshot residue (GSR), fibers, and hair to establish links between suspects, victims, and crime scenes.
Analyze fire debris and samples from suspected arson scenes to identify the presence or absence of ignitable liquid residues.
Operate, maintain, and troubleshoot a wide array of sophisticated analytical instrumentation, including Gas Chromatography-Mass Spectrometry (GC-MS), Liquid Chromatography-Mass Spectrometry (LC-MS), Fourier Transform Infrared Spectroscopy (FTIR), and Scanning Electron Microscopy with Energy Dispersive X-ray Spectroscopy (SEM-EDX).
Meticulously document all analytical procedures, observations, and results in a Laboratory Information Management System (LIMS) and prepare comprehensive, detailed case reports that are scientifically sound and admissible in court.
Provide clear, impartial, and effective expert witness testimony in legal proceedings, including depositions and court trials, explaining complex scientific principles and findings to non-scientific audiences like judges and juries.
Strictly adhere to a stringent chain-of-custody protocols for all evidence, ensuring its integrity and security from receipt to final disposition.
Participate in a robust quality assurance and quality control program, including performing routine performance checks, calibrations, and successfully completing internal and external proficiency tests.
Independently interpret complex analytical data, form scientifically valid conclusions, and be prepared to defend those conclusions under cross-examination.
Conduct peer reviews of casework, reports, and data generated by other chemists to ensure technical accuracy, adherence to protocols, and quality standards.
Maintain a safe and organized laboratory environment by following all safety guidelines, handling hazardous materials correctly, and maintaining chemical inventories.
Develop, validate, and implement new analytical methods and technologies to improve the efficiency, accuracy, and capabilities of the laboratory.
Handle and prepare a diverse range of chemical reagents, standards, and control samples required for analytical testing.
Respond to crime scenes, when required, to provide scientific guidance and assist in the identification, documentation, and collection of chemical evidence.
Manage a demanding caseload, prioritizing tasks effectively to meet deadlines set by the judicial system without compromising the quality of work.
Stay current with the latest scientific advancements, methodologies, and legal precedents in the field of forensic chemistry through continuous education, literature review, and professional development.
Prepare detailed photographic and microscopic documentation of evidence as part of the analytical record.
Perform chemical analysis on non-routine evidence types, requiring adaptability and strong problem-solving skills to develop appropriate analytical schemes.
Author and revise Standard Operating Procedures (SOPs) and technical manuals for laboratory methods and instrumentation.
Train and mentor junior chemists, technicians, and law enforcement personnel on evidence handling, testing capabilities, and scientific principles.
Use statistical methods for data analysis, calculating measurement uncertainty, and establishing the significance of analytical findings.

Secondary Functions

Support the laboratory's accreditation process by assisting with internal audits and preparing documentation for external assessors (e.g., ANAB, ASCLD/LAB).
Contribute to the evaluation and purchasing decisions for new laboratory instrumentation and software.
Collaborate with law enforcement agencies and prosecutors to provide pre-trial consultation, explain the significance of lab results, and clarify evidence submission requirements.
Participate in professional scientific organizations and attend conferences to represent the organization and share research findings.
