Songlin Fei

Professor of Measurements & Quantitative Analysis Dr. Fei’s research program has two primary directions. The first arm of my research program focuses on mapping and modeling of invasive exotic species (IES). The other arm of my research program focuses on large-scale ecosystem dynamics in forests in the eastern United States. Learn More

Brady S. Hardiman

Assistant Professor of Urban Ecology Brady’s research focuses on understanding the interaction of structure and function in coupled natural and human ecosystems. Specific interests include the role of vegetation in urban carbon cycling and the influence of forest canopy structure on long-term carbon sequestration rates. His research is directed toward improving management strategies for urban and rural forests to optimize provision of ecosystem services such as carbon storage and climate mitigation. Learn More

Douglass F. Jacobs

Douglass F. Jacobs

Fred M. van Eck Professor of Forest Biology, Associate Head in the Department of Forestry and Natural Resources, Director of the Tropical HTIRC Dr. Jacobs’ research focuses on the ecophysiology of forest regeneration in response to management and environmental stress. He has specific expertise in nursery systems, plant quality, and plantation establishment to promote reforestation and restoration of threatened forest trees or degraded sites. Learn More

image of Mike Saunders

Michael R. Saunders

Associate Professor of Ecology and Natural Resources Research in the Saunders’ lab centers on the improvement of hardwood silviculture in deciduous forests of North America. His portfolio is diverse, ranging from mid-rotation pruning and thinning practices in precision silviculture systems to development of natural disturbance-based approaches for restoration silviculture systems. Learn More

Guofan Shao

Professor of Forestry Dr. Shao’s overall research interest is digital forestry technologies (DFT), including remote sensing, geographic information systems (GIS), forest modeling, and forestry decision-support systems (DSS). Shao applies DFT in better understanding forest landscape changes and sustaining the management of forest resources. Dr. Shao is especially interested in developing algorithms for accurate land use and land cover mapping with remote sensing, developing web-based GIS protocols for land use analysis and forest conservation, developing applicable forest simulation models for forestry professionals, and developing user-friendly forestry DSS for assisting forestry decision making.  Learn More
