Research areas: Community ecology, seedbanks, invasive species, meta-analysis, social ecology,  theory development.

Research Focus:

I am an integrative scientist with expertise in community theory, sociology, and quantitative methods.  Empirical research involves biogeographical comparisons of many forms of community dynamics (plants, animals, & people). Research within the lab is primarily focused now on positive interactions between plants and animals in deserts.

Keywords:

Community ecology
Deserts
Facilitation
Integrative ecology
Plant-animal interactions
Positive Interactions
