Research Interests:

Theoretical Applied Ecology

My primary research interest is in the use of ecological theory, particularly life history-based models, in population management. I address issues in conservation, harvesting, and the control of invasive species. An in-depth ecological understanding is essential for successful management, and this research focus allows me to ask important ecological questions for species of special concern. For example, I address the ecological factors that make certain species successful invaders of specific communities. At the same time, I examine the ways in which we can manipulate these factors to achieve management goals. My research focuses on population management in a variety of ways, including quantitative theoretical studies of real systems, purely theoretical studies that inform practical approaches, and collaborative empirical work.
