Research interests: Basic and applied aspects of restoration ecology to restore the functionality of and mitigate impacts to forest and rangeland wildlife habitats following disturbance.
Research interests: economic impact analysis, fiscal impact analysis, GIS applications in economic analysis, natural resource policy, the NEPA process, public lands policy.
Research interests: water resource economics, resource and environmental economics.
Research interests: Revegetation of wildland disturbances such as mined lands and on areas impacted by exotic invasions and wildfire, improvement of productivity and revegetation effectiveness to enhance wildlife habitat and understand the mechanisms that contribute to and limit exotic invasions.
Research interests: spatial and temporal patterns of selection in plant populations using techniques in field ecology, molecular genetics and bioinformatics, adaptation of plant populations to local environments, and the implications of local adaptation for the restoration of native plant communities.
Research interests: developing modern and innovative research/extension programs on Forage Agronomy, establishment and Best Management Practices (BMP) for profitable and sustainable forage and livestock production, grazing management and integration with cropping systems, establishment and incorporation of legumes into the grass systems, alternative/multipurpose use of forages, forage nutritive value and seed production.
Research interests: investigating long-term impacts of non-native invasive weeds on native plant communities, developing and improving management strategies to reduce the ecological and economic impacts of invasive weeds, and understanding the inherent resilience of native populations to biological invasion.
Research interests: nutrient cycling in natural, disturbed, and agricultural settings from the perspective of landscape and soil organic matter dynamics, interactions among landscapes, plant communities, and land use affect resiliency and degradation-recovery processes as applied to on-the-ground ecological restoration and sustainable management.
Research interests: Watershed and rangeland hydrology, measurement and modeling hydrologic processes, watershed and land use management decision tools, effects of fire on rangeland hydrologic and erosion processes, characterization of soil hydraulic properties, soil moisture measurement, ecological site characterization and monitoring
Research interests: environmental chemistry watershed land use activities (e.g., energy industry and ag production), sustainability of natural resources (e.g., air quality and water quality).
Research interests: spatial and temporal variability of soil microbial communities, response and recovery of soil microbial communities and their ecosystem functions to various forms of disturbance, influence of land management practices on soil microbial community structure and function, nutrient cycling.
Research interests: rangeland sustainability, including ecological functioning of rangelands, economic values and decision-making, rangeland-dependent communities and families, Sustainable Rangelands Roundtable.
Research interests: Remediation of contaminated soils, sediments and water, and cycling of P and S in the environment, microbially-mediated contaminant transformation, mineral-water interfacial reactions, formation and structure of environmental nanomaterials.
