I initially qualified as a barrister in 2005. Having practiced commercial law at the Bar for three years, I moved to private practice and re-qualified as a solicitor (Ireland, 2009; UK, 2010). From 2011 until 2017, I spent time as in-house counsel in various multinational consultancies based in London, where I focused on combining law with technology to effectively manage high-profile disputes and investigations. I returned to private practice in 2017.

The cases I work on often involve multiple jurisdictions and complex issues.

My key cases have included:

• Acting for a construction company in a £100m claim regarding alleged defective infill;
• Acting for a number of litigants in a negligence and breach of contract claim regarding a financial organisation’s role as a custodian of funds, which were lost as a result of fraud;
• Acting for global financial organisations in LIBOR, HIBOR, SIBOR, FINMA and FX investigations;
• Cross-border litigation of a global technology organisation in FCPA and Bribery Act investigations;
• Acting in one of The Lawyer’s ‘Top 20 Cases of 2022’ in respect of a US$2 billion fraud claim brought by a state-owned bank;
• Acting in a probate and rightful ownership claim in respect of an estate worth in excess of £100m;
• Acting in a high-profile public inquiry examining systemic failures, strategising and advising on acceptable AI-usage and legal technology application to the management of over 100 million documents.

I am widely recognised as a leading authority on AI and legal technology in the UK, with deep expertise in eDisclosure and best practice procedures under the rules of the courts of England and Wales, as well as international arbitral institutions. I sit on the Law Society’s AI Task Force, the board of the International Legal Technology Association (ILTA), the ACEDS Women in AI Board, and several other advisory panels focused on legal innovation, ethics and responsible AI deployment. I have played a key role in drafting a number of foundational protocols in this space, including the court-endorsed ILTA AI Exchange Protocol, the ILTA Active Learning Best Practice Protocol, and its recent GenAI Addendum.

I am a frequent speaker at legal technology and AI conferences, and regularly deliver training and seminars on the intersection of AI, disclosure obligations, and defensible legal workflows. In 2025, I received the AI Visionary Award for contributions to responsible AI in legal practice. In 2022 and 2023, I was listed as a Thomson Reuters Stand-Out Lawyer.

I hold a Bachelor of Civil Law (University of Galway, 2003), a Master’s in International Law (Trinity College Dublin), and a Barrister-at-Law degree (King’s Inns, 2005). I am also an accredited mediator, a member of the Oil and Gas Arbitration Club, and hold various specialist accreditations in eDisclosure, AI and privacy (including CIPP/E).
