Dr. Antti Pessi is currently working on lightning applications over the Pacific Ocean at the University of Hawaii, Department of Meteorology. His ongoing research includes assimilating lightning derived products into numerical mesoscale models. He completed his Ph.D defense in April 2008 and will continue to work at the Department of Meteorology as a Post-Doctoral Scientist.
