My research focuses on digital wetland mapping, wetland hydrology and morphology of hydric soils, hydric soil indicator research, soil carbon measurement, and soil sampling/classification for research. I assist multiple graduate students in their soils research with tools, techniques, and expertise. I do projects that support research such as development of the Universal Soil Classification System, amending US Soil Taxonomy to include Human-altered and Human-transported soils, and heading the IUSS Soil Classification Commission.
My graduate students are involved in: mapping, detecting, and monitoring wetlands with remote sensing; and biofuel production and measuring beneficial changes in soil properties. I advise students involved with carbon sequestration.
Future graduate students will use remote sensing to find and map wetlands in forested areas. They will study soil carbon in peatlands and possibly in tropical wetlands.
I am co-founder and involved with VIP-COI (Virginia Indian Pre-College Outreach Initiative). I am a member of the Native@VT student organization. I have submitted education grants to work with a tribal college (Oglala Lakota College in Kyle, SD) to develop a soils course and will probably be invited to be an adjunct professor at the tribal college to help teach a 2-week wetland soils class next summer. I supervised a program funded by USDA-NRCS to enter over 400 Virginia Tech soils lab pedon descriptions and lab data into their Access® program to be incorporated into a nationwide soils database. I did quality control and researched the lab methods and reviewed/revised all legacy methods and data. I am the NRCS liaison in Virginia and represent VT at all National and Regional Soil Survey Conferences. I host the Soil Taxonomy Forum website for NRCS. I participate actively in the Mid-Atlantic Hydric Soils Committee and am an ex-officio Board Member of Assoc. of State Wetland Managers. I am chair and website host for the Intern. Comm. for Anthropogenic Soils (ICOMANTH) and am chair and web host for Commission 1.4 Soil Classification for Intern. Union Soil Sciences. I am involved with developing a universal soil classification system and writing a simplified version of Soil Taxonomy.
I do not have an extension appointment, but I do extension work by aiding others to obtain and correctly use soil survey, laboratory, and classification data. My philosophy is to look for those who most need my help and advice and who are least enabled to gain that help elsewhere. I especially enjoy working with disadvantaged groups such as indigenous peoples.
