Renato Renner is a theoretical physicist working in quantum information theory and quantum foundations. His research interests range from quantum cryptography and quantum thermodynamics to the foundations of quantum theory and gravity. He studied physics at EPFL Lausanne and ETH Zürich. He then moved to the Computer Science Department, ETH Zürich, to work on a thesis in the area of quantum cryptography. From 2005 to 2007, he held an HP Research Fellowship at the Department for Applied Mathematics and Theoretical Physics, University of Cambridge, U.K. Since 2007, he has been with the Physics Department, ETH Zürich, where he is a Professor of theoretical physics.
