Siân McGibbon
UCL Doctoral Student
Bio:
Siân joined University College London as a doctoral student in 2023. Her PhD research focusses on the application of public law principles to statistical decision-making processes, and in particular on the adaptation of the doctrines of rationality and relevance, supervised by Professors Michael Veale and Rick Rawlings. Siân is a co-author of a number of texts across her areas of expertise, most recently ‘The Law and Practice of Human Rights’ published in October 2025, and is Deputy Editor of the academic journal Judicial Review. She is a graduate lecturer in public law at UCL and supervises postgraduate projects within her field.
Outside of her academic research Siân is a barrister at Landmark Chambers and recognised as a ‘rising star’ and ‘leading junior’ in the area of public and administrative law. Her practice complements her research interests and spans cases before the High Court, Court of Appeal, Supreme Court, Privy Council, and European Court of Human Rights. Before coming to the Bar Siân studied law at University College Oxford and was judicial assistant to (then) Lord Justice Hamblen.
