In a world being reshaped by AI, CEOs and top leaders matter more than ever — their impact magnified by the environment they create for everyone around them.

Professor of Strategic Leadership & Governance at IMD, Lausanne. I study and teach CEO succession, executive impact, and how leaders shape the conditions others decide in.
