Contact: Practice Manager:

Zoe joined Matrix in October 2017 upon the completion of her traineeship. During her traineeship she was supervised by Christopher Brown, Nicholas Gibson, Sara Mansoori, Lorna Skinner, Dan Squires QC and Aaron Watkins.

Prior to coming to the Bar, Zoe spent five years conducting legal policy research and political advocacy in relation to reform of human rights, constitutional and media law. From 2013-2016, she worked in the cross-party parliamentary office of Lord Lester of Herne Hill QC, where she was involved in issues including the application of the Human Rights Act to residential care arranged by local authorities; policy change relating to the funding of safe abortions for rape victims in armed conflict; protection for the BBC’s independence in charter renegotiations; and aspects of the reform of investigatory powers and defamation law in England and Wales.

In 2012, Zoe worked for an independent commission established by the Coalition Government to investigate the case for a UK Bill of Rights. From 2010-2011, she worked in India alongside grassroots disability rights activists, where she conducted research and undertook advocacy work in relation to a federal bill implementing the UN Convention on the Rights of Persons with Disabilities.

Zoe holds an undergraduate degree in Philosophy, Politics and Economics and an MPhil degree in International Relations, both from the University of Oxford, which awarded her a full departmental scholarship for the duration of graduate study. Her MPhil thesis (for which she was awarded a distinction) concerned the politics of international law on torture. She completed her legal education at BPP University, where she was awarded a distinction in the Graduate Diploma in Law and was graded ‘Outstanding’ in the Bar Professional Training Course. Zoe is a member of Lincoln’s Inn, which has awarded her Hardwicke and Lord Denning scholarships and the Buchanan Prize for exam performance.


With Lord Lester QC, Zoe researched and co-drafted Five Ideas To Fight For: How Our Freedom is Under Threat and Why it Matters (Oneworld, 2016). The book charts the evolution of the legal protections given to the rule of law, human rights, equality, free speech and privacy in the UK; and describes ways in which those protections are under threat. The book has been endorsed by Mary Robinson (former UN Commissioner for Human Rights and President of Ireland), Harold Koh (former legal advisor to President Obama), Sir Sydney Kentridge QC, Baroness Helena Kennedy QC; and positively reviewed, including by Lord Pannick QC in The Times. It was cited by UK Supreme Court in the majority ruling in PJS v NGN [2016] UKSC 26.

Zoe has also drafted op-eds for the national press (The Times, Guardian, Telegraph) and written evidence submitted to parliamentary committees, including the Joint Committee on the Draft Investigatory Powers Bill.
