Projects

  • Court Case Forensic & Expert-Testimony Support, e.g.,

    • A multijurisdictional asset-tracing and digital-evidence package for a corruption indictment in an EU member-state, integrating device imaging, chat-extraction, timeline analysis, link/graph modelling, and deliverable of expert testimony.

    • A cyber-incident litigation support project for a large corporation: “preserve → process → analyse” all logs, memory images, cloud buckets, build chain-of-custody, highlight inducement of data exfiltration, provide courtroom-ready reports.


  • AI/ML Augmented Forensic Triage Platform, e.g.,

    • Development of a bespoke platform for a law-enforcement/inspectorate unit: using NLP/ML to auto-cluster and prioritise millions of email/chat records, flag high-risk threads (fraud, insider-threat, collusion), integrate with visual analytics (“link-maps”), then feed downstream into forensic/human review.

    • A video-analytics module for evidential video: machine vision to detect persons/objects/vehicles in CCTV, timestamp correlation with device metadata, produce annotated video-report for prosecution.


  • Capacity-Building for Judicial / Prosecution / Investigative Agencies, e.g.,

    • A training programme for a national prosecution service: deliver modules on digital-forensics, e-discovery, chain-of-custody, AI in investigations, plus hands-on labs (e.g., mobile device extraction, memory forensics).

    • Lab set-up project for a regional agency: design/specify the evidence-locker, acquisition stations, write SOPs, implement quality-assurance matrix (tool validations, version control, hashing logs, audit trails).


  • Incident Response / Breach Investigation & Remediation, e.g.,

    • A major data-breach investigation for a multinational: full forensic triage on EDR logs, endpoint memory/case artifacts, identify root-cause, map attacker kill-chain, prepare remediation roadmap.

    • Insider-fraud detection assignment: use behavioural analytics (ML) on system access logs, detect anomalies, then hinge into forensic extraction (chat records, file transfers) and provide report for internal litigation.


  • Tailored Forensic/AI R&D Pilot, e.g.,

    • Pilot project to integrate deep-learning video/object-recognition into forensic lab workflow, generate a proof-of-concept usable for court-admissible evidence, with validation and technical annex.

    • Development of an explainable-AI model designed to recognise keyword/semantic patterns in massive document repositories (e-mails, contracts) relevant to anti-money laundering/corruption investigations, with audit-trail and model-card for defence/defendants.
