About

I am driven by curiosity about how things work, particularly when it comes to complex products and business models. The work I enjoy most requires both legal rigour and a real understanding of what's driving the business commercially. Most of my career has been in heavily regulated industries, especially energy, where I have advised on some of the defining cases of the past decade. Besides my primary role as an in-house lawyer, I act as an independent antitrust counsel and teach competition law to future practitioners at the Berlin School of Law and Economics. This is a private profile. Views and opinions expressed are solely those of the author and do not necessarily reflect the views of the author's employer or any affiliated organizations.

    In my annual antitrust lecture, I cover European and German antitrust law in depth – cartels, vertical agreements, abuse of dominance, and merger control. Beyond the theoretical foundation, a particular focus is on practical application and best practices for handling in-house antitrust matters. I take pride in teaching future in-house lawyers. More importantly, the exchange with students consistently brings new perspectives and pushes me to further refine my own practice.
