I am a plant population biologist with research focused in two areas:

conservation ecology, including the development of general tools for population and range modeling, as well as building knowledge about particular rare species, and

evolutionary ecology, including bet hedging, life history evolution, breeding system evolution, and comparative analyses of the evolution of climatic niches.

Thus my research encompasses plant ecology, evolution, and conservation. I use a variety of tools – from demography and reproductive biology in natural and experimental settings to phylogenies and trait evolution, from species distribution modeling to hierarchical Bayesian population viability analysis – in order to study plant diversity, its origins, dynamics, and conservation.

recent news I am now an Assistant Research Professor of Forest Ecology at the University of Arizona - an appointment shared between the Laboratory of Tree-Ring Research and the Department of Ecology and Evolutionary Biology. I am building process-based models for forecasting the future distributions of trees in Western North America. More on this project soon!
