Digital Forensics Expert Witness
Digital Evidence Integrity • Expert Report Review • Procedural Reliability
I support courts, prosecutors, law firms and institutions in assessing the integrity and evidential value of digital materials.
My work focuses on identifying methodological flaws, procedural weaknesses and technical inconsistencies in forensic reports, and determining what digital evidence genuinely establishes — and what it does not.

Expert Report Review & Digital Evidence Assessment
Digital evidence plays an increasingly decisive role in criminal, civil and commercial proceedings.
Its reliability, however, depends not only on content, but on methodology, documentation and procedural compliance.
I provide independent forensic reviews that include:
- verification of forensic methodology,
- detection of technical and logical inconsistencies,
- chain-of-custody assessment,
- evaluation of data integrity,
- determination of evidential limitations,
- preparation of review or supplementary expert opinions.
Forensic Analysis of Digital Devices and Systems
Digital evidence often originates from smartphones, computers, servers or industrial systems.
In legal disputes, the critical issue is not merely the device itself, but the reliability of the acquisition and analysis process.
My forensic analysis may involve:
- assessment of device seizure and preservation procedures,
- forensic acquisition (where technically feasible),
- examination of system artefacts (mobile, desktop, IT/OT environments),
- reconstruction of activity timelines,
- detection of system interference or unauthorised access,
- evaluation of surveillance software traces,
- analysis of technical constraints affecting evidential conclusions.
A key distinction is made between material of informational relevance and material possessing genuine evidential weight.
