Markus Müller is a theoretical physicist and an external member of the Rotman Institute. He is also a Research Group Leader at the IQOQI in Vienna and a Visiting Fellow at the Perimeter Institute for Theoretical Physics in Waterloo. His research is motivated by the idea that information and computation play a central role in the foundations of physics. Markus has worked on quantum information theory, quantum thermodynamics, and the question how quantum theory can be derived from simple physical principles. After obtaining his PhD in Berlin, he has been a postdoc in Potsdam, at the Max Planck Institute in Leipzig, and at the Perimeter Institute for Theoretical Physics in Waterloo. Most recently, Markus and collaborators have started to explore how an epistemic view of the quantum state, and of physics more generally, can help overcome some limitations of previous approaches to quantum and space-time physics.
