Professional background

Before joining Fieldfisher, I have gained experience at, inter alia, the European Commission where I commenced proceedings against EU Member States for various breaches of European tax law and in private practice in the UK where I assisted and advised on cases concerning international and European tax law matters.

My focus is on direct tax litigation advising taxpayers and companies on disputes with HMRC having worked on complex and high-value corporate tax cases, as well as cases dealing with the personal taxation of high-net-worth individuals.

I hold an LLM in International and European Tax Law and an LLB in European Law. At present I am working toward qualifying as a Member and Fellow of the Chartered Institute of Arbitrators (CIArb).
