My research interests are broadly in the areas of conservation biology and
biodiversity informatics in the context of global change. Global declines in biodiversity
underscore the need to understand the mechanisms regulating the distribution of species
and ecosystems. My research applies spatial databases and analytical tools, biodiversity
informatics, and ecological niche modeling to explore theoretical considerations in
ecology and conservation biology (e.g. niche vs. neutral theory), aid the discovery of
endangered or rare species, model the spread of invasive species, and predict the effects
of land change, climate change, and sea-level change on species' and ecosystem
distributions.
