I am especially interested in the effects of landscape disturbances on ecological processes. My research efforts focus on the intersection of landscape ecology, pollination ecology and behavioral ecology. My current research is being conducted in two study systems, one located in tropical premontane forest of Southern Costa Rica and the other in a temperate system at the H. J. Andrews Experimental Forest in Oregon. My general interests include: 1) Animal movements and how they are influenced by landscape disturbances. 2) Landscape effects on plant and animal interactions (e.g. pollination, seed dispersal, stability of ecological networks). 3) Landscape genetics. 4) Drivers of species distributions. And 5) The role of social information in resource and habitat selection.
