Me in a minute

It is particularly exciting when I can support my clients when they embark on new creative ventures

I have had a passion for art and archaeology ever since my childhood days, particularly medieval and Renaissance art and late antique relics. Gaining experience in the London, Berlin and Geneva art markets, I quickly found my calling when I interned with the legal team of a major global auction house in London and realised how fascinating it was to engage with the art industry from a legal angle.

Following my time at the University of Oxford, where I completed a Master's in history of art and visual culture, I attended law school in London and went on to assist with the restitution of Nazi-looted art at a law firm in Berlin.
