Forensic Data Science


About Us

The Forensic Data Science Laboratory conducts research to develop methods for evaluation of forensic evidence that are based on relevant data, quantitative measurements, and statistical models; methods that:

  1. are transparent and reproducible;
  2. are intrinsically resistant to cognitive bias;
  3. use the logically correct framework for interpretation of evidence (the likelihood-ratio framework); and
  4. are empirically validated under casework conditions.

In order to develop methods that provide solutions for real forensic-evaluation problems, solutions that have a high probability of actually being adopted in casework, members of the Laboratory conduct research in collaboration with researchers and practitioners who have expertise in particular branches of forensic science.

Members of the Laboratory also conduct research on calibration and validation of forensic-evaluation systems, and on communication of forensic science to courts, research whose results are applicable across many branches of forensic science.

In addition to research, members of the Laboratory provide training in forensic inference and statistics to forensic practitioners and to lawyers, and contribute to the development of standards and guidelines for forensic science.

– Reading group

  • We have a weekly meeting at which we discuss published papers related to forensic data science. These are usually recently published papers. Sometimes we invite the authors of the papers to join us for the discussion. We usually meet online on Mondays at 09:00 UK time (for the last meeting of Jan 2022 through to the end of March 2022 we have moved to Fridays).

  • Meetings are open to Laboratory members, adjunct members, and invited guests only. If you have an existing relationship with the Laboratory, or one of more of its members or adjunct members, and would like to receive invitations to join the reading-group meetings, please send a request to the Laboratory Director. Requests will be considered on a case by case basis.

  • Schedule of past and upcoming readings
