Andrew Hansen is Professor in the Ecology Department and Director of the Landscape Biodiversity Lab at Montana State University. He teaches macroecology to undergraduates and landscape ecology to graduate students. His research focuses on interactions among biodiversity, climate change, and land use, with an emphasis on landscape management and protected areas. He received a Ph.D. in ecology at the University of Tennessee and the Oak Ridge National Laboratory. Dr. Hansen was a post-doctoral scientist in landscape ecology at the University of the Witwatersrand in South Africa and with the Scientific Committee on Problems in the Environment (SCOPE) in France. He then joined the faculty of Oregon State University, where Dr. Hansen studied ecological approaches to forestry. At Montana State University, he is focusing on rates of land use change and consequences for protected areas such as Yellowstone National Park. Results from Yellowstone provided the basis for comparative study of land use change surrounding several nature reserves and biodiversity within reserves for six greater ecosystems around the world. Dr. Hansen also led a national study of global change effects on forest biodiversity as part of the US Assessment of Climate Change and Variability. He is currently studying vulnerability of national parks to land use and climate change across the United States. His work uses a combination of remote sensing, computer simulation and field studies. This research has been funded primarily by NASA, US Department of the Interior, Environmental Protection Agency, US Department of Agriculture, conservation organizations, and the timber industry.

Dr. Arjun Adhikari is a Postdoctoral Researcher at the NC CSC based on Dr. Hansen's lab in the Ecology Department of Montana State University. He earned his Ph.D. in ecology from Baylor University. His doctoral research focused on investigation of climate change impacts on carbon dynamics of shrubland using remote sensing observation of shrub density and biomass, plant ecophysiological response of key shrub species to elevated drought, and computer modeling of ecosystem processes. He is working on vulnerability assessment of forests and grasslands to current and future climate change in the greater ecosystem of NC CSC domain. Particularly, his research focuses on analyzing the changes in spatial patterns of natural cover due to current and projected land use changes along NC CSC domain. His research area also includes species distribution modeling under current and future climate change scenarios predicted by IPCC. In addition, he is focused in predicting grassland phenology response to potential climate, soils, and landform change under IPCC climate change scenarios. He is equipped with multiple research methods, including remote sensing, GIS, plant water potential, gas exchange, computer modeling, and various statistical tools.
