Mariya is of Anglo-Bulgarian-Cypriot heritage and fluent in Bulgarian and Greek. She also speaks French at an intermediate level. She is completing a pupillage at 3PB and will be doing a civil pupillage.

She joins 3PB having been a Judicial Assistant to the Rt. Hon. Lord Justice Leggatt and Lady Justice King DBE at the Court of Appeal and with the Hon. Mr Justice Stewart, assigned to assist with the Kenya Emergency Group Litigation in the High Court. Her work as a JA involved producing case summaries and bench memos on matters before the court, discussing the case with judges, and attending court with them. This has advanced her skills in rigorous legal reasoning, organisation, legal research, drafting skills and evidence review.  Mariya joins us with a reputation already for excellent time-management and great communication and advocacy skills.

Mariya also worked as a Research Fellow on the WiseGrid project at Queen Mary University (sponsored by the European Commission) where she assisted Dr. Rafael Leal-Arcas, the principal investigator on the project. Mariya’s research focused on the implications of the gradual ‘smartening’ of the energy market; a developing area of the law.  Mariya was previously a legal consultant at the International Bar Association (IBA), where she assisted Dr. Mark Ellis (Executive Director) with the investigation into the compliance of the Libyan regime trials with International Human Rights instruments. She also assisted a Task Force of IBA lawyers by undertaking legal research and drafting the final IBA report on the independence of the legal profession.

After completing the BPTC Mariya undertook a 6-month judicial internship with Judge Silvia Fernandez de Gurmendi, former President of the International Criminal Court, where she carried out legal research on issues arising in the context of international criminal and human rights law, and assisted by drafting the orders and judgments of the Chamber.  She has previously worked as an intern at the Office of MEP Ivailo Kalfin, former Deputy Prime Minister of Bulgaria, at the EU Parliament in Brussels.

Pro Bono

In her work outside chambers, Mariya formerly volunteered with Liberty and Reprieve, where she drafted papers to assist in death penalty and wrongful imprisonment cases, and has provided pro-bono assistance to DiyLaw, a legal charity that provides assistance to litigants in person.
