Job Details

The Ecosystem & Soil Microbial Processes Lab led by Dr. Pete Homyak in the Department of Environmental Sciences at UC-Riverside is accepting applications for students interested in pursuing a Ph.D. We research how soil microbial and abiotic processes control the exchange of elements such as N, P, and C across the soil–water–atmosphere interfaces to infer how anthropogenic disturbances and changes in global climate may alter ecosystem biogeochemistry and function. Several field sites are available to develop projects including sites in the Sierra Nevada along an elevation gradient, several chaparral sites along an atmospheric nitrogen deposition gradient, a rainfall manipulation experiment in Pinyon-Juniper woodland, recently burned chaparral sites across California, and high-temperature agroecosystems. Several novel tools are available in the lab to develop research projects including δ13C-CO2/CH4 and N2O isotopomer trace gas analyzers, LI-COR automated soil flux chambers, and instruments in FIRMS ( and the ESRL (

The priority application deadline is December 1st, though applications will continue to be accepted through January 5th ( Competitive candidates will have a B.S. and/or M.S. degree in soil science, microbiology, environmental science, ecology, or a closely related discipline.
