Summary

I'm a quantitative ecologist interested in understanding the mechanisms that drive plant population and ecosystem dynamics, from individual plots to landscapes. I use this understanding to anticipate and predict the impacts of environmental change in basic and applied settings. My work relies heavily on inference and statistics to synthesize data and models.

My current research topics include:

  • Demographic and environmental controls on landscape-scale resilience and restoration 
  • Demographic and population modeling methods
  • Impacts of environmental variability on population and community dynamics

Sources of seasonal water supply forecast uncertainty during snow drought in the Sierra Nevada
Uncertainty attribution in water supply forecasting is crucial to improve forecast skill and increase confidence in seasonal water management planning. We develop a framework to quantify fractional forecast uncertainty and partition it, and demonstrate the uncertainty framework with statistical runoff models.

Resilience Is Not Enough: Toward a More Meaningful Rangeland Adaptation Science
Transdisciplinary science and management in rangelands requires more than just conceptual social-ecological frameworks. Additional methodological concepts need to include: 1) relationship building; 2) shared meaning making; and 3) a commitment to continual conversations and learning.
