Quantum Gravity and Noncommutative Geometry


Professor Harms has most recently worked on a comprehensive theory of dark energy, inflation and black holes. Other recent projects include the quantum description of microscopic black holes and their relation to extended objects such as strings and membranes, the calculation of black hole and naked singularity decay rates in large extra dimensions, black hole decay rates in noncommutative spacetimes, and dark energy as a manifestation of the Casimir energy of noncommuting, compact extra dimensions. Professor Harms received his doctoral degree from Florida State University.
