  • Prepare amplified DNA fragments for analysis and operate sophisticated genetic analyzer instrumentation, primarily utilizing Capillary Electrophoresis (CE) to generate DNA profiles.
  • Conduct in-depth analysis and interpretation of complex DNA data, including single-source profiles, complex mixtures, and low-template DNA, using specialized software like GeneMapper ID-X.
  • Utilize advanced probabilistic genotyping software (e.g., STRmixâ„¢, TrueAllele®) to interpret complex DNA mixtures and calculate likelihood ratios for statistical evaluation.
  • Compare evidence DNA profiles with profiles from known reference samples (suspects, victims) and search against national and state databases via the Combined DNA Index System (CODIS).
  • Author comprehensive, detailed, and impartial technical laboratory reports that clearly document all procedures, results, statistical interpretations, and conclusions for use in the criminal justice system.
  • Provide clear, concise, and effective expert witness testimony in depositions, hearings, and court trials regarding laboratory procedures, DNA analysis results, and statistical significance.
  • Meticulously maintain and document the chain-of-custody for all handled evidence, extracts, and amplicons to ensure evidentiary integrity.
  • Perform and document routine calibration, maintenance, and quality control procedures on all laboratory instrumentation and equipment to ensure operational readiness and accuracy.
  • Successfully complete regular internal and external proficiency tests to demonstrate and maintain technical competence and meet accreditation requirements.
  • Participate in the internal validation of new laboratory methods, instrumentation, software, and chemistries to enhance laboratory capabilities and efficiency.
  • Independently manage a demanding caseload, effectively prioritizing tasks to meet investigatory and judicial deadlines without compromising quality.
  • Conduct thorough technical and administrative reviews of casework, reports, and data generated by other analysts to ensure scientific accuracy and adherence to laboratory protocols.
  • Serve as a subject matter expert and provide training, mentorship, and technical guidance to junior analysts, technicians, and law enforcement personnel.
  • Maintain a deep and current understanding of scientific advancements, emerging technologies, and evolving legal standards in the field of forensic DNA analysis.
  • Adhere strictly to all established laboratory safety protocols, quality assurance standards (FBI QAS), and ISO/IEC 17025 accreditation requirements in every aspect of the work.

Secondary Functions

  • Support ad-hoc data requests and exploratory data analysis.
  • Contribute to the organization's data strategy and roadmap.
  • Collaborate with business units to translate data needs into engineering requirements.
  • Participate in sprint planning and agile ceremonies within the data engineering team.
