Under the guidance of the Chief Forensic Toxicologist and Director of the Forensic Laboratory Division, the forensic laboratory seeks a highly motivated candidate to investigate, design, and help implement AI and machine learning (AI/ML) models that enhance laboratory workflows and improve case processing. This role will focus on integrating AI and ML into key lab processes to improve drug identification in untargeted suspect screening of Quadrupole Time-of-Flight Mass Spectrometry (QTOF) data, as well as developing predictive models to assist in case conclusions. By contributing to the development of an SQL- and Python-based Laboratory Information Management System (LIMS), the student will be instrumental in creating infrastructure that enhances efficiency, accuracy, and scalability in forensic science.

This role offers an opportunity to help transform forensic laboratory practices by implementing AI-driven infrastructure that enables faster case processing, more accurate drug detection, real-time data insights, and automated quality control. The candidate’s contributions will enhance lab adaptability, reduce human error, optimize resources, and improve forensic reporting—creating a future-ready, data-driven laboratory environment.

Qualifications

Education: Possession of a Bachelor's degree from an accredited college or university in a life science or physical science with 16 semester hours in general and organic chemistry courses, a statistics course, and two (2) analytical and/or interpretive courses in forensic toxicology, pharmacology and chemistry.

Verification: Applicants may be required to submit verification of qualifying education and experience at any point in the application and/or departmental selection process. Written verification (proof) of qualifying experience must verify that the applicant meets the minimum qualifications stated on the announcement. Written verification must be submitted on employer’s official letterhead, specifying name of employee, dates of employment, types of employment (part-time/full-time), job title(s), description of duties performed, and the verification must be signed by the employer. City employees will receive credit for the duties of the class to which they are appointed. Credit for experience obtained outside of the employee’s class will be allowed only if recorded in accordance with the provisions of the Civil Service Commission Rules. Experience claimed in self-employment must be supported by documents verifying income, earnings, business license and experience comparable to the minimum qualifications of the position. Copies of income tax papers or other documents listing occupations and total earnings must be submitted. If education verification is required, information on how to verify education requirements, including verifying foreign education credits or degree equivalency, can be found at http://sfdhr.org/index.aspx?page=456.

Desirable Qualifications:

• Understanding of data science, bioinformatics, computer science, or a related field.
• Experience in AI/ML modeling and data analysis with Python, SQL, and other data processing tools.
• Familiarity with mass spectrometry data, and experience in forensic toxicology or a related discipline.
• Understanding of LIMS systems, data pipelines, and workflow automation in laboratory environments.
• Interest in:
  • Development and Integration of AI/ML Infrastructure: Researching and designing infrastructure that supports AI/ML integration, including scalable data pipelines for efficient QTOF data management.
  • Identification of Positive Drugs in Untargeted Suspect Screening: Creating ML algorithms that enhance sensitivity and specificity in drug detection, reducing false positives and negatives.
  • Case Prediction Modeling: Developing predictive models that leverage case data to support forensic conclusions and optimize case management.
  • Data Management and Analysis: Ensuring smooth data flow within the LIMS and maintaining thorough documentation for reproducibility, validation, and regulatory adherence.
  • Research and Publication: Publishing findings in peer-reviewed journals, presenting at conferences, and staying current with advancements in forensic science, AI, and ML.

Supplemental Information:

Nature of duties may require sustained physical effort involving manual skill, dexterity, hand/eye coordination, and the ability to lift and carry equipment and supplies up to 50 lbs.
