I am a plant ecologist interested in the responses of individual species and populations to global change. I combine ecological, physiological, and genetic data to assess the impacts of environmental stresses on plant growth and reproduction, and potential implications for changes in species distributions. This work has both theoretical and applied value, and frequently aims to provide practical guidelines to land managers interested in ecological restoration and conservation. Examples of my research include: characterizing the disruption of plant-mycorrhizal symbioses by invasive plant species; modeling source-sink dynamics of plant invasions to help prioritize eradication efforts; identifying priority populations of alpine plants for conservation; and quantifying the effects of rising atmospheric CO2 on plant reproduction.
