Discovery.
For most of human history, black holes could only be inferred — never seen.
In 2019, we changed that. The first image revealed the shadow of a black hole 55 million light-years away, with a mass of 6.5 billion suns. Capturing it required an Earth-sized telescope — and decades of scientific and technological innovation. Working with my team and international partners, I helped advance Very Long Baseline Interferometry and establish the global Event Horizon Telescope collaboration that made the image possible.
The questions that led to this discovery continue to drive my research. Through my ERC Advanced Grant M2FINDERS, we investigate magnetic fields and the launching of relativistic jets near supermassive black holes.
collaboration.
Much of my career has been devoted to building collaborations — connecting researchers, observatories, and institutions across national boundaries to pursue shared scientific goals.
I have learned that trust takes time to build, and that sustaining cooperation can be as demanding as achieving the science itself.
responsibility.
Scientific experience brings responsibility beyond one’s own research.
Today, I contribute to international dialogue and institutional advice on scientific freedom, research security, and cooperation under geopolitical pressure.
How can we preserve openness while addressing legitimate security concerns? And how do we sustain scientific ties when political relations become strained?
