Hanna Sianko

Hanna Sianko combines rigorous legal training from the United Kingdom and the United States with a sophisticated background in international development. She holds a Master’s degree from the London School of Economics and Political Science, where her research culminated in a dissertation on human rights violations. This dual foundation equips her to analyze complex global challenges not only through a legal lens but also with a nuanced understanding of policy implications.

Her legal expertise is concentrated at the nexus of international criminal law, human rights law, and international commercial law, with a particular focus on the critical intersection of criminal accountability and human rights protection. This specialized knowledge is built upon diverse practical experience, including work at the Community Legal Advice Center in London, which provided broad exposure to civil, regulatory, and commercial matters. This role solidified her understanding of access to justice and procedural safeguards, while separate experience in corporate environments honed her ability to merge exacting legal precision with pragmatic commercial insight. Her analytical and advocacy skills were further sharpened through high-level competition, including leading a team in the Herbert Smith Freehills Competition Law Moot and participating in a prestigious arbitration competition.

In her current practice, Ms. Sianko navigates complex, high-stakes international legal frameworks. She provides strategic counsel on a wide spectrum of Interpol-related matters—including challenges to notices, diffusions, and data protection issues—alongside handling complex extradition cases. Her work is centered on advising clients facing formidable cross-border legal challenges and advocating for the protection of their rights within international cooperation systems.

A steadfast commitment to safeguarding individual rights and ensuring access to justice serves as the cornerstone of her practice, blending meticulous legal reasoning with uncompromising ethical advocacy. Her fluency in English, Russian, and Spanish provides a distinct advantage, allowing her to deliver a comprehensive and globally-informed legal perspective to her clientele.
