I am a forest ecologist at the University of Arizona School of Natural Resources and the Environment and Laboratory of Tree-Ring Research. For the past six years I have been conducting research on the interactions among climate, fire, insect outbreaks, and management practices in forested ecosystems. I am using the results of this work to advise cooperators with the U.S. Forest Service, the Nature Conservancy, and the Department of Defense on development of sustainable management plans. My current work entails the development of a comprehensive climate change risk assessment for a group of stakeholders across three regions of the Southwest. Prior to moving to Arizona in 2009, I worked as a forest entomologist helping to develop sustainable silviculture in the boreal forests of Quebec.
I have lived and worked in most of the forested systems of North America, covering a diverse array of ecosystems including conifer forests in western Washington where I grew up, to hardwood forests of Michigan and Pennsylvania, subtropical forests in central Florida, and fire-prone forests across the Southwest. I have a B.S. from Penn State University, an M.S. from the University of Quebec, and a Ph. D. from the University of Arizona.

14. Mario Guevara
Mario is a full time PhD student in the Department of Plant and Soil Sciences at UD. His research focuses on understanding and quantifying spatial and temporal dynamics of soil organic carbon and soil moisture by using spatial statistics and machine learning techniques to analyze environmentally-relevant “big data”. His research aims to a) improve the understanding of development of soil spatial indicators including soil biological integrity, soil hydraulics and soil physical stability; and b) to analyze changes of soil biogeochemical and hydrological dynamics in space and time at several scales, over different vegetation structures and land uses.
My research focuses on understanding the consequences of human-caused global changes, especially the impacts of climatic changes (particularly drought), biological invasions, eutrophication (e.g., increased N deposition), and altered disturbance regimes for biodiversity and ecosystem structure and function. Within this context, my research addresses questions about the functional roles of species in ecosystems, the causes and impacts of loss and gain of genetic and species diversity, the factors that influence species coexistence and patterns of species abundance, and the relative strength of bottom-up (resources) vs. top-down (consumers) controls in structuring communities. My research employs a mixture of empirical approaches (observational, experimental, comparative and synthetic) and utilizes C4-dominated grasslands as experimentally tractable and dynamic model systems. I currently am the lead of the Drought-Net RCN (www.drought-net.org) and am director of the Semi-Arid Grassland Research Center at CSU.

20. Peter Jorgensen
I am a transdisciplinary researcher applying macroecological methods and methods from evolutionary biology to questions regarding global societal challenges including global environmental change. My current research takes an integrative approach to questions of global natural resource use – including trends in national consumption and applied evolutionary biology including resistance evolution. In applied evolutionary biology, I am focused on building a socio-ecological foundation to how humans govern system subject to contemporary rapid evolution as well as loss of biodiversity. I have throughout my career emphasized transdisciplinarity and worked to innovate foundational infrastructures, as well as research itself, in international research communities. This is evident through my co-founding and leadership of the International Network of Next-Generation Ecologists, governing board membership of the International Association for Ecology and current facilitation of a regional network – the Oresund Early Career Sustainability Researchers network.
21. Rachel Gallery
My research group studies the ecology of soil microbes. Microbes define soil health, support ecosystem services, and maintain plant diversity. They are critical to ecosystem resiliency, especially in the context of climate change and the conservation challenges we currently face. Working across a range of ecosystems from lowland tropical forests, to high elevation conifer forests, to semi-arid grasslands, we use field-based experiments, microbiological techniques, and contemporary genetic sequencing tools to test the effects of plant-microbe interactions on plant and microbe community diversity. We work with model developers to understand how environmental shifts will alter these interactions and accurately measure and predict ecosystem function responses.
