Odysseas is recognized by all major directories as a leader in the fields of international arbitration and cross-border business litigation. Who's Who Legal: Thought Leaders Global Elite (2024) and Who’s Who Legal Arbitration and Commercial Litigation (2019-2024), describe him as a “first-class legal mind”, “a superb lawyer of tremendous intellectual integrity” and “a dedicated and effective communicator”, with clients noting in particular that they are “impressed by his diligence and legal expertise”, “his creativity, attention to detail and ability to handle complex issues”, his “devotion to the client’s interests” and his “ability to build the strongest case possible in any given circumstance”. Legal 500 (2020-2023) also recognizes him as a “key lawyer” in international arbitration, investment treaty arbitration proceedings and claims involving sovereigns and notes his “particular expertise in investor-state disputes”.

He is also endorsed by Financier Worldwide, which recognizes him as a “Future Star and Power Player” in Complex Disputes.

Odysseas acts in arbitration and litigation cases spanning a broad range of industry sectors, jurisdictions, procedural rules and applicable laws. He regularly represents clients in, among others, the transportation, banking and financial services, mining, telecommunications, shipping, infrastructure, nuclear energy and utilities sectors, and has particular expertise in matters involving complex, fact-heavy and cross-border commercial disputes and claims involving state parties or governments, including claims under concession agreements and international investment treaties.

Odysseas holds advanced degrees in law from Harvard Law School and the University of Hong Kong. He has received several prizes and awards, including the Harvard University Scholarship and the Li Ka Shing Prize (also known as the Best Ph.D. Thesis Award).
