He also represents clients in commercial arbitration proceedings in the UK and abroad, including under the LCIA, ICC, SCC and UNCITRAL rules. His experience includes advising on complex energy and infrastructure disputes between investors and states/state-owned entities, particularly involving Russia, Ukraine and Kazakhstan.

Tomas recently wrote a book chapter on tribunal-appointed experts, in a commentary on the UNCITRAL Model Law (Cambridge University Press). He has also served as part of the leadership of several prominent arbitration organisations and initiatives, including as an Advisory Board member of the Institute for Transnational Arbitration.  He also serves as a legal specialist to the American Bar Association's Rule of Law Initiative.
