Research and Interests

My current research focuses on biological invasion. More specifically, I have focused my research on identifying the distribution of invasive plant species in California at both a regional and local scale. My primary goal is to identify the current distribution of invasive plants and to predict their potential impact on native plant communities. My techniques have focused on the use of field data, GIS, remotely sensed imagery, and spatial statistics for modeling species distribution. I am also interested in the impacts of non-native animals and the spread of diseases. In addition to biological invasion, I also have an interest in topics related to conservation biology, environmental studies, and spatial analysis. I am particularly interested in looking at issues related to the use of GIS/Remote Sensing and spatial analysis with a focus on the Modifiable Areal Unit Problem (the MAUP) and it's impact on biogeographical analysis.
