Increasing anthropogenic demands for food, energy, and raw materials are driving global-scale environmental changes with profound impacts on biodiversity. Our research group focuses on characterizing and mitigating anthropogenic impacts on the environment with an emphasis on freshwater ecosystems. We combine fieldwork with the development and application of theoretical, statistical, and meta-analytic modeling tools to conduct interdisciplinary, policy-relevant research across multiple spatial scales.

Specific research themes include:
• Understanding how environmental change impacts species, communities, and ecosystems, and developing effective mitigation strategies
• Examining how future demand for food and bioenergy impacts biodiversity conservation
• Disentangling the roles of climate change and anthropogenic land-use change on biomass fires and their impact on aquatic biodiversity in Southeast Asia
• Uncovering the effects of climate change, land-use change, dams, and invasive species on aquatic communities in the Southern Appalachians
• Elucidating mechanisms underlying large-scale patterns of species richness, turnover, and co-occurrence to inform regional and global conservation priorities
• Understanding human attitudes toward environmental sustainability to develop compelling conservation messages

I am currently recruiting graduate students to start in Fall 2019 or Spring 2020. Interested in finding out more? Let’s talk! Email me at xgiam@utk.edu.
