# Invited Speakers

**Bianca Dittrich** is a faculty member of the Perimeter Insitute for Theoretical Physics, Waterloo Ontario, and an adjunct Professor at the University of Waterloo and University of Guelph. Her main research interests are in quantum gravity, including the problem of time, loop quantum gravity, spin foam models. She also has related interests is in lattice gauge theories and topological quantum field theories. For more information visit her webpage.

**Sean Gryb** is a a Postdoctoral researcher at the Theoretical High Energy Physics group at the University of Radboud in Nijmegen. His main interest is in classical and quantum gravity, with a particular focus upon the shape dynamics approach to gravitation. He is also interested in Mach principles and other foundational issues related to symmetry and quantization in physical theory. For more information visit his webpage.

**Philipp Hoehn** is a a postdoctoral researcher at the Perimeter Institute for Theoretical Physics, Waterloo Ontario. His interests concern multiple aspects at the interface of quantum theory and gravitational physics, including the reconstruction of quantum theory from information inference principles, the relation between elementary space-time structure and quantum communication, and discrete gravity models. For more information visit his webpage.

**Tim Koslowski** is a a postdoctoral researcher in the relativity research group at the University of New Brunswick In Fredericton, New Brunswick. He is primarily interested in quantum gravity, in particular shape dynamics, Loop quantum geometry condensate and considering exact renomalization group techniques in quantum gravity. He has philosophical interests the use of Machian principles in the foundations of gravity. For more information visit his webpage.

**Brian Pitts** is a Senior Research Associate in the Faculty of Philosophy at the University of Cambridge. Brian works on issues in the philosophy of physics, especially space-time, gravity and particle physics, and has also written a number of papers on gravitation physics. He is also interested in issues in the general philosophy of science including underdetermination, confirmation and induction, and the history of early modern astronomy. For more information visit his webpage.

**Oliver Pooley** is a a University Lecturer in the Faculty of Philosophy at the University of Oxford and a Fellow and Tutor in Philosophy at Oriel College, Oxford. He work in the philosophy of physics and in metaphysics. Much of his research focuses on the nature of space, time and spacetime. He is also interested in the ways in which work in general metaphysics can (and should) inform the interpretation of physics. For more information visit his webpage.

**Carlo Rovelli** is a professor at the Universite de la Mediterranee, Marseille, France and is responsible for the quantum gravity group at the Centre de Physique Théorique, Aix-Marseille University. His main research focus is quantum gravity, and he is among the founders of the theory of loop quantum gravity. He has also worked in the history and philosophy of science. For more information visit his webpage.

**Donald Salisbury** is Professor of Physics and Co-Director of the Program in Global Science, Technology and Society at Austin College in Sherman, Texas. His main interest as a physicist lies on constrained Hamiltonian dynamics and the implementation of general covariance in a phase-space formulation of General Relativity. He also a longstanding interest in the history of the history of General Relativity and Quantum Gravity. For more information visit his webpage.

**Kurt Sundermeyer** is affiliated to the Physics Department of Freie Universität Berlin as a Privatdozent and to the Max-Planck Society for the History of Science (Berlin) as a consultant. He grew up in particle physics and came from the very early string theory to constrained systems in general. From 1985 he worked in an industrial research institute in the area of artificial intelligence. After his retirement in 2003, he rediscovered his roots as a theoretical physicist, and got specifically interested in symmetries in fundamental physics. Presently he tries to understand what's it all about time in physics.
