My research focus is to work at the interface between science and application to deepen our understanding of the social and environmental factors that shape where and when species occur on a given landscape to improve decision-making and conservation.  My research group works on developing and applying novel quantitative modeling techniques to understand how human drivers of land-use change (e.g. agriculture) affect biodiversity using birds as indicators. We work collaboratively with practitioners, decision-makers, stakeholders, and local communities to design research that supports the development and implementation of strategies that reconcile biodiversity conservation, sustainable development, and human well-being.
