Experimental Search for Quantum Gravity

Dr. Sabine Hossenfelder is a research fellow at the Frankfurt Institute for Advanced Studies. Her research focuses on topics ranging from the physics of black holes to cosmology to the foundations of quantum mechanics. She devoted more than ten years to investigate the question where to best search for experimental evidence of quantum gravity. She worked at Nordita (Nordic Institute for Theoretical Physics), Stockholm, Sweden; the Perimeter Institute, Waterloo, Ontario, Canada; the University of California, Santa Barbara, USA and at the University of Arizona, USA.
