George D. Cody specializes in chemical-structural analyses of solid phase organics. His research is focused on determining the diagenetic reactions that define organic sediment maturation. Other interests include examining the molecular structure of extraterrestrial organic solids contained within carbonaceous chondritic meteorites and more recently, comets. He received a Ph.D in geosciences from Pennsylvania State University in 1992, and a B.S. in geology from University of Massachusetts at Amherst in 1982.
