Ali started practice in October 2005 upon completion of 12 months pupillage in Chambers. He has appeared in Courts in both England and France, and acted in international arbitrations and specialist adjudications such as in the Intellectual Property Office. In England, he has appeared at all levels including the Supreme Court, the Court of Appeal, the High Court QBD (including the Administrative Court and the Commercial Court ), Chancery Division (including the Companies Court) and the Patents Court. He has also represented English clients in Courts of Appeal of Paris and Aix-en-Provence.

Prior to pupillage, Ali qualified as an Avocat at the French Bar, worked for S.G Archibald in Paris and Dewey Ballantine in London and was a stagiaire with the European Contract Law Team at the European Commission in Brussels. He was awarded the David Karmel Award by Gray’s Inn and the Entente Cordiale scholarship by the British Council.

In 2004, he was a Visiting Research Scholar at the Institute of European and Comparative Law at the University of Oxford and he holds a PhD in EC Conflict of Laws from Kings College London, which he completed under the supervision of Professor CGJ Morse, and which was examined by Professor Richard Fentiman and Professor Ian Fletcher. Prior to entering practice, he published some of his research including “The Action Plan on European Contract Law: perspectives for the future of European contract law and EC consumer law” (with Jens Karsten), 2003 Journal of Consumer Policy 159-195, “The inclusion of mandatory rules in an optional EC contract law instrument” 2004 European Business Law Review, 41-71
