Stephen Faulkner


Steve Faulkner is a supervisory research ecologist at the Leetown Science Center in Kearneysville, WV. Growing up exploring the forests of central Maryland led him to pursue his B.S. and M.S. degrees in Forestry from Louisiana State University. He received his Ph.D. in wetland biogeochemical ecology at Duke University. After graduate school, he held faculty positions at LSU before joining USGS in 2002. Steve has studied various aspects of forest and wetland ecosystem sustainability and restoration including soil redox chemistry, carbon and nitrogen biogeochemistry, and the effects of climate and land-use change on ecosystem services. He currently serves as Chief of the Aquatic Ecology Branch at Leetown where he leads a team of seven scientists with research programs in genetics, aquatic ecology, and landscape ecology.
