Research in my group focuses on ecosystem processes,
especially carbon, water, and nutrient cycling. I study biogeochemical
responses to global changes, such as rising atmospheric CO2, climate change, N
deposition, and altered land use.
For example, I am currently studying how altered
precipitation and warming alter carbon and nitrogen cycling in Arizona's
ecosystems, how elevated CO2 alters nitrogen cycling and hydrology of scrub oak
woodlands, and how increased temperature influences the nitrogen cycle in grasslands.
In addition to understanding ecosystem responses to such
perturbations, I am interested in how ecosystem responses can feed back to
alter the pace and even direction of future global changes.
A second major thrust of my research addresses how single
species can affect ecosystem processes, for example, how infestation with the
piñon-needle scale alters the water budget of piñon-juniper woodlands, or how
mycorrhizae influence decomposition of fine roots.
I teach courses in general ecology, microbial ecology,
ecosystem ecology, and stable isotope techniques.
