James (Greg) Ferry obtained his Ph.D. degree from the University of Illinois and postdoctoral training at the University of Georgia after which he accepted an Assistant Professor position in the Department of Anaerobic Microbiology of Virginia Tech. After achieving the rank of Professor, he moved to Penn State with the title of Stanley Person Professor. There, he founded the Center for Microbial Structural Biology and is a charter member of the Penn State Astrobiology Research Center. He is currently a member of the National Academies of Science, Engineering and Medicine Intelligence Science and Technology Experts Group and serves on the editorial boards of Applied and Environmental Microbiology and the Journal of Bacteriology.

The study the enzymology and molecular biology of anaerobic microbes from the Archaea domain
The laboratory investigates the enzymology and molecular biology of anaerobic microbes from the domain Archaea. Anaerobes--microbes living without oxygen--comprise nearly one-fourth of all living protoplasm on earth and are found in a variety of Earth’s anaerobic habitats which include: (i) estuaries and the deep sea, (ii) rice paddies (iii) the rumen of cattle, and (iv) the gut microbiome of humans and other monogastric animals. Anaerobes of Earth’s biosphere convert plant biomass to methane in a process that is an essential link in the global carbon cycle. The process impacts the environment and human health in other important ways. Biologically produced methane is a greenhouse gas more powerful than carbon dioxide. On the other hand, the process is used commercially to dispose of domestic and industrial wastes. Many anaerobes are able to detoxify hazardous pesticides, and methane from renewable biomass is a clean-burning alternative energy source. Our research on ancient enzymes from the domain Archaea is contributing to an understanding of the origin and evolution of life and directly impacts the field of Astrobiology.
