Summary

Dr. Johnston has published about 200 refereed journal articles, invited reviews, refereed book chapters and has recently edited a book on the surface chemistry of clay minerals. He is a physical chemist who has applied advanced spectroscopic, structural and thermal methods to study of applied problems in soil and water science.  His areas of specialization include stabilization of soil organic matter, fate and transport of anthropogenic compounds in the environment, mineral-water and mineral-organic interactions, and developing new methods to quantify greenhouse gas emissions from soils.  He has established research collaborations around the world.  He has built a highly-successful\ collaboration with researchers at Michigan State University with approximately 40 publications and funded by NIH (NIEHS Superfund) and USDA.  He regularly teaches the undergraduate introductory soils class (AGRY 255) in partnership with other faculty, and graduate level course in soil chemistry (AGRY 540), soil biogeochemistry (EAPS 518).  In the past, he has taught environmental science (NRES 290), methods of greenhouse gas emissions (AGRY 598) and climate change in Africa. He has graduated 9 PhD students and 5 MSc students, hosted many visiting scholars and has supervised about 7 postdoctoral scholars.
