Focus on soil degradation and sustainable agriculture in the tropics (especially Africa), bio-energy, greenhouse gas emissions from soil and headwaters, and synchrotron-based methods for soil research.
Enid Martinez
Carmen Enid Martínez is a soil and environmental chemist and biogeochemist. Her research and teaching foci are soil minerals, soil organic matter, reactions at the solid-solution interface, and their associated (biogeo) chemical processes.
Murray McBride
Murray McBride's long-term interests focus on understanding the behavior of contaminants at the soil-water interface in the environment, with particular emphasis on the phytotoxic and zootoxic trace and heavy metals. He is interested in the issue of soil health, as it is impacted by the contamination of soils by various waste materials, commercial fertilizers and manures.
Jeffrey Melkonian
Jeffrey Melkonian's work involves the application of dynamic simulation modeling combined with field experimentation to better understand resource use, productivity, and the fate of nitrogen and water in agricultural and biomass crops.
Jonathan Russell-Anelli
Jonathan Russell-Anelli's research examines the spatial dynamics and characteristics of the environment. The focus is on land cover, soil and management topology and their effects on biogeophysical processes. His research also addressed the spatial arrangement and characterization of soil properties including nutrient and contaminant distribution.
Michael Rutzke

Michael Rutzke

Senior Research Associate
Michael Rutzke has a strong interest, natural ability and resources to develop new technologies in the field of analytical chemistry. These provide researchers in other fields new opportunities for cutting edge research in cell biology, human nutrition, and environmental sciences.
Matt Ryan
Over the next decades, agriculture will undergo a transformation as farmers learn to produce more food while decreasing the environmental impact of their practices. Between feeding another two billion people and adapting to climate change, we face unprecedented challenges. However, at the same time, there has never been as much interest in agriculture as more and more consumers want to know the origins of their food and new farmers are increasingly from non-farm backgrounds.
Tim Setter is Professor and Chair in the Section of Soil and Crop Sciences, with joint membership in the Section of Plant Breeding and Genetics. He currently collaborates with researchers at CIMMYT, the International Maize and Wheat Improvement Center, on studies of drought tolerance of maize, and collaborates on cassava research with colleagues at national institutes in Nigeria, Ghana, and Uganda, and at the International Institute of Tropical Agriculture (IITA).
Stephen Smith
For the past 30 years Stephen Smith has been directly involved in resource inventory, land use mapping, land use planning, and technical education. The application of remote sensing, geographic information systems (GIS), and global positioning systems (GPS) technologies to cultural and environmental issues is his primary professional interest. The projects he has undertaken have ranged from the development of farm management systems to mapping the extent of an invasive plant species across a multi-county region.
