About Me

I specialise in information, technology and communications law.

I support my clients in situations where innovative technologies face legal issues. My expertise includes areas such as the Internet of Things (IoT), online services, social media, traditional media and information security. I am a widely recognized expert for all fields of technology regulation, including ePrivacy, data protection and data ownership, telecommunications regulation, IP and trade secrets.

I regularly represent my clients in disputes. Some of my cases were handled before the highest German courts, including the German Constitutional Court. In disputes, I combine my expertise in the regulatory fields that form the basis of the case with my skills as a dispute lawyer and strategist. I also represent my clients in negotiations.

As an expert on information and data law, the German Lawyers Association (DAV) has appointed me as member of its Committee for Information Law. Within the IAPP, I served as a member of the IAPP's European Advisory Board. I also hold the certification of a Certified Information Privacy Professional/Europe (CIPP/E).

Within Bird & Bird, I am a member of the Innovation Steering Group and of the German Legal Tech Group.
