Terry Slonecker


Terry Slonecker is a Research Geographer with the USGS/National Civil Applications Center.  He specializes in remote sensing and other geospatial analyses of hazardous waste, invasive species, landscape change, heavy metals and other fugitive contaminants in the environment. His current research interest include VIS/NIR/FTIR spectroscopy and imaging spectroscopy, especially as it relates to hazardous substances and invasive species.  He holds a Master’s degree in Geography and a Doctorate in Environmental Science, both from George Mason University. With 30+ years of experience with the U.S. Air Force, the U.S. Environmental Protection Agency and the U.S. Geological Survey, he has served on many special assignments including the Gore-Chernomrydin Commission, the U.S. Group on Earth Observations, the Civil Application Committee, the Spring Valley World War 1 chemical weapons cleanup and has recently served as a remote sensing instructor in Afghanistan.  He has participated in several emergency response efforts including Three Mile Island, Hurricane Katrina and the Gulf Oil Spill and has served, on several occasions, as an expert witness on remote sensing for the Federal government.
