Daniel is an international commercial disputes specialist with particular expertise in international arbitration and English Court litigation. He provides strategic advice and input for clients from the earliest stages of contractual disputes, through to representing clients in fully-fledged arbitration or litigation proceedings and any subsequent enforcement action. Daniel's work relates to projects, companies, governments, state entities, and individuals spanning many sectors and a range of regions worldwide.

With an English law background primarily focused on international commercial arbitration, Daniel's work relates to projects, companies, governments, state entities, and individuals based in various regions worldwide, including MENA, UK/Europe, Central and South Asia, sub-Saharan Africa and Russia/CIS. He has represented clients in matters ranging from shareholder and joint venture disputes, through to aviation-sector litigation and repossessions, through to delay and disruption claims in infrastructure and construction projects (please see "Experience" for selected representative matters).

Daniel has represented and advised clients in a broad range of types of disputes procedures, including international arbitration (ICC, LCIA, HKIAC, SCC, AAA/ICDR, DIFC-LCIA, DIAC, LMAA, ICSID, UNCITRAL administered by PCA, and many other leading arbitral rules and institutions), English Court litigation (in particular, Commercial Court, Chancery, Court of Appeal), mediation, and expert determination.

Daniel also frequently advises as to other strategic aspects of multi-jurisdictional disputes where arbitration, litigation, and/or regulatory proceedings may be afoot in a number of jurisdictions worldwide. This can include, for example, applying for urgent injunctive relief (or responding to such applications) or pursuing enforcement of judgments and arbitral awards.
