I am interested in a broad array of ecological questions,
particularly in (but not limited to) desert systems. While
many ecological questions focus on plants as the primary
drivers of ecosystems, I believe the importance of other
ecosystem components are often underestimated. Therefore, my
work focuses on the interface between the abiotic and biotic
factors that structure plant communities and assist in
ecosystem function. These include climate, soils,
herbivores, granivores, pollinators, microbes, etc.
Interactions between and among these organisms can help us
better understand ecosystem function. I am interested in how
these interactions may change in response to fire, invasive
species, global change and land management practices.
NOTE TO PROSPECTIVE GRADUATE STUDENTS:
Students interested in post-fire natural recovery and
restoration are strongly encouraged to apply although I am
open to topic suggestions.
