My research interests lie in spatial patterns, processes, and mechanisms underlying species interactions and distributions, and in applied conservation. I draw on the fields of spatial ecology, plant community ecology, plant-animal interactions, conservation biology, and epidemiology; and I strive to bridge the gap between science and conservation practice. At NCEAS, I am working on a project to quantify the economic and ecosystem impacts of non-native forest pests and pathogens in North America. Both the economic and ecosystem effects of these introductions should be considered in developing public policy. collapse
