‘He has a vibrant practice and an excellent reputation in the market. Given the prevalence of investment treaty disputes and the inclusion of arbitration clauses in large commercial transactions and investment ventures, we believe that this is an area of increasing importance to our clients.’

‘Jeff’s investment treaty expertise will add to our bench strength in this important and busy area and will balance in precisely the right way,’ said Penny Madden QC, co-chair of the international arbitration practice group. ‘His practice complements our exciting growth in London and across New York, Dubai and Hong Kong.’

‘Jeff is recognized as a rising star in arbitration,’ said Cyrus Benson, co-chair of the international arbitration practice group. ’As a former adversary to Jeff in a major arbitration proceeding, I have the utmost respect for him as a first-rate technical lawyer and advocate.’
