exploring the universe.
bridging continents.
thinking at the horizon.
I am an astrophysicist who has spent decades at the frontier of discovery and international scientific collaboration. Today, I bring that experience to selected engagements in science, international cooperation and public dialogue.
first picture of a black hole.
For most of human history, a black hole could only be inferred — never seen.
In 2019, we changed that. Six and a half billion solar masses. Fifty-five million light years away from us. An image that required the resolution to photograph a donut on the moon.
With my team and international partners, we turned a scientific vision into a global scientific enterprise. We advanced Very Long Baseline Interferometry by linking radio telescopes across the globe into a single Earth-sized instrument. That made the first image of a black hole possible.

As emeritus, I continue my research and take on a select number of engagements where experience and perspective can make a difference. Curiosity, a sense of responsibility, and a collaborative spirit continue to shape how I work.

science at scale.
Discovery.
I study distant galaxies and the role of supermassive black holes — how magnetic fields shape their environments, and how relativistic jets form in their vicinity.
For over two decades, my group and international partners advanced the capabilities of global radio interferometry until imaging a black hole became possible. Today, my ERC Advanced Grant M2FINDERS continues that pursuit at the jet-launching region of M87’s supermassive black hole.
translation.
Discovery becomes lasting value when scientific insight connects with technology, infrastructure, and the people who build both.
The first image of a black hole required more than a bold idea. It required decades of building: connecting telescopes across continents, advancing technology, and developing the methods that turned vast amounts of data into trustworthy images.
That experience continues to shape how I think about the conditions that make ambitious science possible — through technology, institutions, international collaboration, and people that make them work.
responsibility.
Scientific experience brings responsibility beyond one’s own research. Today, I contribute to conversations and advisory work where scientific independence, public trust, and the long-term resilience of research institutions and systems are at stake — particularly in international and transatlantic contexts.

advisory.
I work with institutions and leaders where long-term perspective matters more than quick answers — helping to sharpen questions, navigate complexity, and think through strategic choices.
My advisory work draws on experience in science strategy, international cooperation, research governance, and institutional leadership.
mentoring. supervision.
I work with individuals navigating roles that carry weight beyond themselves through collegial, reflective conversations grounded in shared experience.
My perspective has been shaped by leading international collaborations, building research environments, and supporting the development of scientific careers.
My approach is informed by certified training in systemic coaching and supervision.
discourse.
I have spent decades at the intersection of discovery and responsibility — and I believe scientists who have been there have an obligation to speak.
I contribute through lectures, interviews, and long-form conversations on science, research policy, and international cooperation.
