She has a Ph.D. (1993) in Agronomy and Soil Science and has been a certified Professional Soil Scientist by the Soil Science Society of America since 12/20/99. Dr. Knox has 25 years of responsible experience in environmental science, with emphasis on the biogeochemistry and geochemistry of metals and radionuclides in natural and contaminated soils/sediments; the transformation, transport, and bioavailability of contaminants; and the remediation of contaminated soils/sediments.

She has published more than 95 scientific papers, book chapters, and patents; has presented numerous papers at scientific meetings and international conferences; and has organized several sessions and special symposia on contaminants in soils and sediments for international conferences/meetings such as the International Conference on Remediation of Contaminated Sediments, International Conference of Biogeochemistry of Trace Elements (10th, 11th, and 13th ICOBTE), International Conference on Heavy Metals in the Environment (15th  and 16th ICHMET2012), and others.

Dr. Knox is nationally and internationally recognized as one of the leading authorities in the area of active capping research. She has received several awards including a DOE Women of Excellence in Science and Engineering award and several Key Contributor Awards due to crucial contributions to the strategic goals of the Savannah River National Laboratory. Her participation in professional societies includes serving on the editorial boards for both the International Society of Environmental Forensic Journal and Journal of Archives of Agronomy and Soil Science.
