Approach to Responsible AI in Analytical Training

Uses AI within statistical training to demonstrate how it can safely accelerate analysis, reporting and material preparation.

Covers hallucination, fabricated references, confidentiality, data protection, inappropriate method selection, over-reliance and the need to validate outputs.

Teaches delegates not to let AI determine the analytical question and builds the statistical understanding needed to recognise when AI is polishing the wrong answer rather than solving the right problem.

Uses Microsoft Copilot and ChatGPT professionally for report writing, training-material development, prospect management and promotional content, while retaining human verification and professional judgement.

Selected Consultancy and Transformation Engagements

National COVID-19 Reporting, Forecasting & Capability Building | Gibraltar Health Authority Dec 2020 – Jul 2022 | Gibraltar

Designed and delivered an automated national COVID-19 reporting system in ten weeks using existing resources and tools, avoiding the need to procure or develop a new platform from scratch.

Integrated reporting on who had COVID-19, hospitalisation, likely place of acquisition, vaccination dates and status, contacts, discharge outcome and readmission, producing automated briefings for ministers and senior officials.

Spoke with ministers at the start of the project to understand requirements. The resulting system automated subsequent ministerial and senior-official briefing and received ministerial commendation.

Developed forecasting and SIR models and calculated local R measures. Sat with local staff to explain the epidemiological and statistical reasoning, provided free access to training materials and transferred the models for continued development.

Helped build sustainable local capability: staff continued to manage and develop the models, and the analytical capability subsequently included a Chief Statistician within the health authority.

Completed a hospital-wide systems review by interviewing system owners and clinicians, assessing standalone systems, integration potential and coding consistency. Produced recommendations for PAS implementation and built a Power BI/Power Query demonstrator.

Patient Management & National Reporting | Open Door Mental Health Charity Consultancy engagement

Replaced a large, unstable and undocumented spreadsheet environment that manually combined multiple client files and created substantial copy-and-paste risk.

Built a Power Query data pipeline with a Power BI front end that automatically assimilated client reports, resolved coding differences and prepared nationally required reports defined in Information Standards Notices.

Reduced additional reporting effort to minimal routine administration once care information had been entered, with one administrator maintaining daily updates and handling minor issues.

GDPR Strategy & Implementation | Charities and small businesses Consultancy engagements

Developed GDPR strategy and implementation documentation, helping organisations identify their data, clarify accountability and strengthen practical compliance arrangements.

Executive and National Leadership

GDPR Lead | NHS Digital Feb 2018 – Apr 2018 | Leeds

Mapped the Information division to identify every data asset, including assets held in technical areas where teams did not always recognise that they held datasets.

Used the Information Asset Owners network previously created and chaired as the starting point; identified gaps, established IAOs where possible and ensured responsibility for DPIAs was assigned and completed.

Worked across information, technical, governance and protection teams, using detailed investigation where ownership and accountability were unclear.

Led six Heads of Service with overall responsibility for around 300 staff and approximately £50–100 million in staffing and resources.

Maintained data-quality teams across each area and led escalation when serious issues required publication delays, communication through the National Statistician, liaison with submitting organisations, work with data-governance/protection teams or engagement with the ICO.

Kept organisational structures fluid to meet changing demand, merging teams and moving analysts and team leaders through specialties to broaden skills and increase resilience.

Embedded documented processes, senior-role shadowing and deliberate movement across areas to support succession and test whether documentation and knowledge-transfer arrangements worked.

Created directorate-wide briefings, anonymous improvement and challenge channels, and a weekly newsletter publishing answers and progress. Staff increasingly raised issues and subsequently became more comfortable addressing concerns directly.

Recruited senior staff within own functions and provided senior input to recruitment elsewhere across the organisation.

Negotiated national clinical-audit tenders and contracts with HQIP across budget, scope, deliverables, methodology, timescales, staffing/resources and data requirements.

Maintained delivery during major resource shocks, reprioritising work, changing scope and timescales and seeking additional income when budgets were redirected during the swine-flu response.

Sponsored an IT system intended to support the National Library of Quality Indicators. Stopped the project after more than £100,000 had been spent when evidence showed the supplier was unlikely to deliver, resisting pressure to continue because of sunk cost.

National Governance, Standards and Earlier Career

Chair / Founder | National Indicator Governance Board 2011 – 2015; 2017 – 2018 | National

Created and chaired a cross-system governance board with all national NHS bodies signed up, establishing common oversight for the design, assurance and introduction of national indicators.

Specialist Information Manager | The Health Informatics Service Apr 2002 – May 2007 | West Yorkshire

Managed a specialist service covering research and statistical advice, geographical mapping, prescribing analysis, community information and library services across Huddersfield, Halifax, Dewsbury and Wakefield, including acute, mental-health and primary-care organisations.

Leadership & People Development

Leads by challenging thinking, helping people see problems from other perspectives and building confidence through recognition of strengths.

Has mentored people within formal reporting lines, elsewhere in the same organisation and across organisational boundaries.

Creates learning cultures in which honest mistakes are surfaced and addressed without blame. Establishes who was affected, communicates the issue and remediation, supports team-led review, turns lessons into wider education and follows up to confirm that the resolution worked.

Identifies potential and creates opportunity. Has supported relatively junior staff into stretching senior responsibility, backed emerging talent and used coaching, shadowing and knowledge transfer to create future leaders.

Uses data storytelling and clear communication to make complex analytical issues accessible to ministers, boards, clinicians, managers and other non-technical audiences.
