Admitted to the bars of New York and Paris, I practice in Paris with an emphasis on information technology and intellectual property law.

My specific knowledge of these areas results from my music and photographic activities as well as my inner passion for computer science.

I have acquired my experience in international law firms, where I have been able to assist companies ranging from early-stage start-ups to global multinationals, since 2006, on litigation and transactional matters.

I wish to assist you in the implementation of your projects, in order to optimize the immaterial assets of your company, be it in relation with personal data management (clients, prospects, employees), intellectual property, editorial contents or your partnerships with service providers.
