Patrick Joseph Espy
About
Patrick Espy is Professor of Atmospheric and Environmental Physics at the Norwegian University of Science and Technology (NTNU) in Trondheim, Norway. After receiving his PhD from Utah State University in 1986, he worked in the US, Sweden and the UK before joining NTNU in 2007. His research focuses on the solar, auroral and anthropogenic forcing of middle atmospheric chemistry and dynamics. In addition to ground-based measurements, he is a member of several international rocket and satellite teams studying these phenomena.
