Scientist at heart. Technology leader in practice.

Senior Director for AI & Automation in Drug Discovery
Merck / Darmstadt and Boston

Building systems that make science move.

I build and scale AI-driven and automated discovery capabilities across chemistry and biology, then carry the same operating instinct into science, deep-tech ventures, and the communities I help lead.

Build the system. Grow the people. Keep the science honest.

My work sits where science, technology, and operating reality meet. I build platforms, teams, and ventures that turn difficult scientific problems into decisions and progress. The same instinct guides how I work in a lab, a boardroom, a startup, or a sports hall.

03 / The science

Keep the physics. Increase the reach.

My academic foundation is in theoretical chemistry and molecular simulation. Today I carry that scientific discipline into applied platforms, open research, public talks, and the decisions that make complex technology useful.

The other half of leadership is showing up locally.

Volleyball

I am an amateur player at VC Walldorf, where I also serve as volunteer chair. Coaching is where I practice making understanding useful to someone else.

VC Walldorf
Club leadership

As volunteer chair, I help create the conditions in which people can play, improve, and keep coming back.

Jugendförderung

Meine wichtigste Coaching-Aktivität ist das Coaching wettbewerbsorientierter männlicher Jugend in der Region Nordbaden.
