Harald Frey received his education in Germany and after 3 years in industry and 6 years at the Max-Planck-Institute for Extraterrestrial Physics he joined the Space Sciences Laboratory (SSL) at UC Berkeley in 1997. He has been working on the detection and analysis of optical phenomena in near-Earth space using cameras on satellites and on the ground. He was the instrument scientist for the Far Ultraviolet Imager on the NASA IMAGE mission that observed aurora in response to external driving by the solar wind. He was the US project scientist for the Imager for Sprites and Upper Atmospheric Lightning (ISUAL) which was a collaboration between the Taiwanese Space Program Office (SPO) and SSL to observe sprites, elves, halos, and gigantic jets from space.
