Juliya is a UK-qualified Partner resident in the New York office. Her practice focuses on international arbitration and cross-border disputes.

In arbitration, she has represented clients under the LCIA, ICC, UNCITRAL, SCC, SIAC, Swiss Chamber and ICSID rules. These cases often concern complex jurisdictions (CIS, Africa, and Middle East), complex industries (mining and energy), and complex claims (billion-dollar corporate shakedowns, or parallel criminal and civil proceedings). She has done a number of court-based applications regarding arbitration, including injunctions, set-aside claims, and enforcement proceedings.

Juliya frequently provides strategic advice to support legal claims from Commonwealth jurisdictions, several before the Privy Council. These claims have ranged from judicial reviews, public law and criminal proceedings, submissions for consular assistance concerning individuals charged abroad, and individual mandate submissions before UN bodies such as the Working Group on Arbitrary Detention, and the individual mandate of Special Rapporteurs.

Juliya is active in the field of business and human rights and is a ranked individual in this area in Chambers and Partners (2019).
