Alexander acts as counsel and arbitrator in complex commercial disputes, focusing on international commercial and investment treaty arbitrations.  

With over two decades of experience, Alexander has handled scores of commercial and investment treaty arbitrations, valued from the low millions to multiple billions of USD.  Alexander is ranked for his work in international arbitration by Chambers & Partners and by Lexology (Who’s Who Legal), and by Legal 500 for his work in energy and mining.  "His analytical skills are outstanding. Alexander has the rare gift of being able to identify the relevant points immediately and point them out directly and without hesitation."  (Chambers 2026). "Alexander is a heavy hitter with a deep expertise in arbitration matters. He is a finely honed and compelling advocate, both orally and on paper." (Legal 500, 2024).  

Many of the disputes Alexander has handled have involved complex jurisdictional issues and procedural complexity, and they have frequently involved application of foreign laws.   Examples include a series of high-value disputes relating to long term gas supply arrangements subject of four parallel investment treaty and commercial arbitrations; seven concurrent arbitrations concerning the repudiation of long-term contracts in the mining sector; and a long-running, complex dispute relating to the construction of a nuclear power plant.  Alexander has conducted disputes involving numerous regions of the world, including Western and Eastern Europe, the Middle East, North and sub-Saharan Africa, Central Asia, India and North and South America.  His work has involved the rules of all major arbitral institutions including ICSID, ICC, LCIA, CRCICA, SIAC, HKIAC and AAA/ICDR, as well as ad hoc arbitrations including under the UNCITRAL Rules.

Alexander’s practice covers numerous diverse industries.  He has a significant focus on disputes in the energy, mining and construction / infrastructure sectors, investment treaty claims and commercial disputes, and has handled disputes involving industries and subject matters including  commodities, agribusiness, shareholder and joint venture disputes, M&A, pharmaceuticals, IP and licensing, distribution agreements, hospitality, food and retail industries, aviation and insurance, among others.  Alexander handles proceedings before the English courts, including arbitration-related applications.  

Originally qualified as a barrister, Alexander was a partner in one of the world’s preeminent international arbitration practices in a global law firm for several years, before joining Quadrant Chambers in 2021.  As such, he is astute to the commercial context of disputes and the needs of end clients, as well as being well placed to work with or manage teams of lawyers.
