Reads regulation like a threat model.
Staff Engineer, Security Assurance & Audit at Nscale
Start a conversationResearcher turned practitioner
I sit where academic rigour meets the unglamorous reality of getting an organisation certified, compliant and genuinely more resilient.
I hold a PhD in information and network security and privacy, and now work as Staff Engineer, Security Assurance & Audit at Nscale, after several years consulting in GRC and data protection.
My research, ten peer-reviewed papers on side-channels, IoT safety and traffic analysis, taught me to treat evidence as the product. In practice I turn frameworks into outcomes: vCISO, vISM and DPO engagements across health, finance and industry, and standards-based assurance explained to very different audiences, often under time pressure.
Career and education

2026 – now
Staff Engineer, Security Assurance & Audit
Nscale
Hands-on lead for assurance and audit: SOC 2 Type II, ISO and customer commitments. I own audit readiness for new sites, one control framework across SOC 2, ISO and NIST, evidence standards, and the relationship with external auditors, working with GRC engineering on evidence automation.
-
2025 – 2026
Data Protection Officer
Sapphire, UK
Independent oversight and advice on UK and EU data protection law, including the GDPR. I led privacy governance (policies, training, audits, records of processing), breach management and incident response, DPIAs and DSARs.
-
2024 – 2026
Senior Security Consultant
Sapphire, UK
Led complex GRC engagements across compliance, assurance and risk. Product owner for Third-Party Risk Management, with vCISO and vISM support in healthcare, finance and industry. I led tenders across ISO 27001, 27701, 22301, 22237 and 42001, the GDPR, DORA, NIS 2, the NCSC CAF and NIST CSF.
-
2023 – 2024
Security Consultant
Sapphire, UK
Subject-matter expert on DORA and NIS 2. I led ISO 27001, 22301 and 27701 engagements from gap analysis to internal audit and certification, plus awareness training and business continuity, across transport, logistics, education, healthcare, manufacturing and finance.

2022 – 2023
Postdoctoral Researcher
Heriot-Watt University, Edinburgh
SECRIOUS project: how new-code and non-traditional entrants engage with cyber security in software engineering, with human-centred approaches to security education across cyber security, games research and HCI.
-
2018 – 2022
PhD, Cyber Security
University of Strathclyde
Thesis: Security of Robotic Workflows. Calibration security and operational privacy in robotic, cyber-physical and safety-critical systems: passive side-channel threats, access control and blockchain-based approaches, using machine learning and signal processing.
-
2014 – 2018
BSc Computer Science, First Class
Heriot-Watt University
Software development, networking and cyber security. My final-year project built a tool to identify and remediate IoT devices vulnerable to the Mirai malware in real time. Advanced coursework in network security, AI, machine learning and distributed systems.
