WELCOME

My research focuses on ecosystem function and community-ecosystem inter-actions. I like to take a genes -to -ecosystems approach, and I've worked extensively with a multidisciplinary working group using Populus as a model system. Although my work branches out in many different directions, at the core, I am always asking how diversity affects ecosystems. Much of my research is on trees because these tremendous organisms have a large effect on carbon, water and nutrient dynamics in forest ecosystems. Most of my papers deal specifically with how variation among trees affects communities and ecosystems in terms of water, carbon, and nutrient dynamics. This work has employed specialized technology to measure whole-tree and leaf-level physiology, fine-root dynamics, and ecosystem carbon flux. My lab's current work is divided between riparian cottonwood forests in Utah and Arizona, and temperate rain-forests in western Washington. I'm really excited about the work we've been doing estimating carbon budgets for diverse second-growth rainforests. For more on this topic, check out the links to the EEON project. My lab also continues to work extensively with an international working group in understanding how genetics affect ecosystems, from large herbivores and microbes to Carbon, water and Nitrogen budgets.
