Since the discovery of the cosmological origin of GRBs there has been growinginterest in using these transient events to probe the quantum gravity energyscale in the range 10^16--10^19 GeV, up to the Planck mass scale. This energyscale can manifest itself through a measurable modification in theelectromagnetic radiation dispersion relation for high energy photonsoriginating from cosmological distances. We have used data from the gamma-rayburst (GRB) of 6 December 2002 (GRB021206) to place an upper bound on theenergy dispersion of the speed of light. The limit on the first-order quantumgravity effects derived from this single GRB indicate that the energy scale isin excess of 1.8x10^17 GeV. We discuss a program to further constrain theenergy scale by systematically studying such GRBs.Comment: 10 pages, 3 figures, accepted for publication in ApJ
