Core Responsibilities

Primary Functions

Conducts comprehensive chemical, physical, and biological analyses on physical evidence submitted to the laboratory by law enforcement agencies.
Performs serological and DNA analysis on physiological fluids, tissues, and other biological samples, including extraction, quantification, amplification (PCR), and genetic profiling.
Interprets complex DNA mixture profiles and compares generated DNA profiles to victim, suspect, and elimination samples, as well as searching against the CODIS database.
Examines, identifies, and compares latent fingerprints, palm prints, and footprints using AFIS/NGI databases and manual comparison techniques.
Analyzes suspected controlled substances, illicit drugs, and pharmaceutical preparations to determine their identity and quantity, utilizing instrumentation like GC-MS and FTIR.
Performs toxicological analysis of biological specimens for the presence or absence of alcohol, drugs, and other toxic substances to determine their role in a subject's death, illness, or impairment.
Conducts firearms operability testing, serial number restoration, and examination of ballistics evidence, including cartridge cases and bullets, for comparison using an integrated ballistics identification system (NIBIN).
Analyzes and compares trace evidence such as hairs, fibers, paint, glass, soil, and gunshot residue (GSR) using various forms of microscopy and microchemical methods.
Responds to and processes major crime scenes to document, collect, and preserve physical evidence, ensuring the chain of custody is meticulously maintained from collection to courtroom.
Authors detailed, comprehensive technical reports that document analytical procedures, observations, and conclusions in a clear, concise, and scientifically accurate manner.
Provides expert witness testimony in depositions, hearings, and court proceedings, clearly explaining scientific principles, testing procedures, results, and their significance to the trier of fact.
Maintains and calibrates highly technical laboratory equipment and instrumentation, performing routine quality control checks and troubleshooting issues to ensure optimal performance.
Strictly adheres to established laboratory protocols, safety procedures, and quality assurance/quality control (QA/QC) guidelines to ensure the integrity of results and maintain laboratory accreditation.
Participates in and successfully completes regular internal and external proficiency testing in the assigned forensic discipline to demonstrate and maintain technical competence.
Validates new scientific methods, instruments, and software for use in forensic casework, including drafting validation plans, conducting experiments, and writing summary reports.
ins- Manages a demanding caseload, prioritizing assignments based on investigative and judicial timelines while meeting established turnaround time goals.
Provides technical and administrative review of casework performed by other forensic scientists to ensure accuracy, quality, and adherence to laboratory policies.
