Independent forensic science. Clear expert evidence.
RHEM Labs is a forensic science laboratory providing independent analysis, expert reports and evidence for legal matters.
RHEM Labs works with solicitors, barristers and other instructing parties to examine digital evidence and address the forensic questions that matter to a case.
THE QUESTION BEHIND THE RECORD
A machine trace is not automatically a human act.
“The phone shows X.” Does the underlying evidence sustain that inference? A record may establish an event without identifying who caused it, why it occurred or whether a person knew about it.
We examine the source artefacts, acquisition and system behaviour where necessary, then explain the competing interpretations and limits.
From timestamp to attribution ↗01 / FORENSIC EXPERT WITNESS SERVICES
What you can instruct us to do.
Start with the disputed inference and the opinion you need. Engagement types describe the work; technical capabilities describe the evidence involved.
- 01
Expert reporting
Independent forensic reports and expert evidence addressing the question in dispute.
- 02
Digital evidence review
Independent review of digital material, existing findings and the inferences drawn from them.
- 03
Preliminary review
A focused first assessment of the disputed inference, available material and need for further examination.
- 04
Conferences & oral advice
Technical conferences with solicitors and counsel to clarify evidence, questions and the scope of an opinion.
- 05
Supplementary analysis
Further examination of new material, alternative explanations or a defined issue arising after an initial report.
- 06
Expert conferences & joint reports
Participation in expert conferences and preparation of joint reports where applicable to the instruction.
- 07
Court attendance & oral evidence
Independent explanation of forensic findings, methods and limitations in proceedings.
02 / RESEARCH & DEVELOPMENT
Real forensic problems. New scientific questions.
Casework informs our research. Part of the proceeds from forensic expert work is reinvested into developing methods, tools and knowledge that can support future practice.
Forensic practice → research → new methods and knowledge → better-informed forensic practice.
Inside the research program ↗03 / INSIGHTS & PUBLICATIONS
From the laboratory
Reviewing a police digital-forensic report
A practical starting point for solicitors assessing the link between a technical finding and the inference advanced in a matter.
AIPIO 2026: forensic science in support of intelligence
AIPIO Intelligence 2026 sharpened a question for RHEM Labs: can forensic information about image origin reach analysts early enough to inform a decision?
When is independent digital-evidence review warranted?
Indicators that a focused forensic review may resolve a material uncertainty before a larger examination is commissioned.
FORENSIC INSTRUCTIONS
A question about digital evidence?
For legal practitioners and professional organisations: discuss the forensic question, available material and timeframes.
