Longstanding goals in ecology include mapping species distributions and deriving the habitat characteristics that explain those distributions; the potential for global climate change to re-align suitable habitat makes such assessment crucial, particularly with the addition of invasive species. I use field experiments and statistical modeling to address big ecological questions:

1. What are the environmental drivers that shape species distributions, and are these distributions coordinated with the species niche requirements?

2. How does the strength and nature of species interactions shift across environmental and biological gradients?

3. How will species distributions and interactions (communities) shift in a changing climate with the addition of exotic invasive species and migrating native species?
