Overview

When the Technology Is Complex, the Evidence Is Contested and the Stakes Are High

I am an independent technical expert with nearly 25 years of professional experience in digital forensics, cybersecurity, complex computer systems and the investigation of electronic evidence. My background combines specialist technical investigation and digital forensic examination within UK law enforcement, commercial IT systems design and development, and professional and academic research into data integration and analysis technologies.

A significant part of my work involves cybersecurity incidents and major data breaches, including technical investigation, incident response and the examination of technical evidence in the civil litigation that follows. My instructions have involved major multinational corporations, government bodies, public authorities and high-net-worth individuals, often in complex and high-profile matters across several jurisdictions.

For legal teams facing complex technical issues, my value lies not simply in examining the evidence but in understanding the technology behind it, identifying weaknesses and inconsistencies, testing competing technical explanations and presenting clear, independent conclusions capable of withstanding scrutiny.

Computer Expert Witness

I have provided expert evidence in civil and criminal proceedings, acting for claimants and defendants, prosecution and defence, and as a single joint expert. I present complex technical evidence clearly and in a form the court can rely on.

Digital Forensic Examination

From digital devices and electronic communications to large-scale business systems, I examine electronic evidence and assess the authenticity, integrity and reliability of digital documentation, including evidence that may have been manipulated.

Complex IT Disputes

I advise on the technical issues behind high-value commercial and IT disputes, including the implementation and fitness for purpose of enterprise systems, software copyright, patent claims and electronic tendering.

Cyber Breach Investigation

I have been instructed in litigation arising from some of the most widely reported data breaches in the UK and Ireland, examining how systems were compromised and what the technical evidence shows about the security measures in place.

Nearly 25 Years of Experience

Notable Case Highlights

I have undertaken numerous complex technical investigations, nationally and internationally, involving high-value commercial disputes, cybersecurity incidents, major data breaches, high-net-worth individuals and serious international criminal cases. My work includes the identification of manipulated electronic evidence, the independent review of existing forensic findings and the assessment of the authenticity, integrity and reliability of digital documentation.

I have acted for claimants and defendants, prosecution and defence, and as a single joint expert (SJE). My evidence has been subject to judicial scrutiny, including recognition by the Commercial Court for my contribution as an expert witness.
