Job description

A postdoctoral researcher position is available in the Department of Environmental Sciences at the University of California, Riverside. This position is split between two laboratories within the Department: the Catchment Hydrology and Spatial Analysis Lab ( and the Pedology Lab. We are looking for a highly-motivated, independent researcher to join a collaborative, NSF-funded project to address four key knowledge gaps at the interface between roots,
regolith, rocks, and climate (aka the R3-C frontier):

(1) In what ways do bedrock properties interact with overlying regolith to influence the development of the soil pore networks and soil hydraulic properties that control water flow?
(2) How does the spatial distribution of mineral weathering, influenced by the development of pore networks from bedrock-regolith interactions, control the manner in which roots acquire water and nutrients?
(3) How do critical zone thickness and root water uptake dynamics interact to regulate evapotranspiration dynamics under changing water supply and demand conditions?
(4) Do roots modify soil structure by imposing depth-dependent wet-dry cycles that mediate aggregate size distributions, and thus the ability of the regolith to preserve organic carbon?

The successful candidate will lead the hydrologic modeling experiments using R-SWMS, ParFlow.CLM, and EcoSLIM at four of the project sites (Reynolds Creek CZO, Coal Creek, CO, Konza Prairie Biological Station, and Southern Sierra CZO) and assist with the analysis of proximal sensed imaging (multistripe laser triangulation and VisNIR hyperspectral scanning) of soils and regolith samples. The postdoctoral researcher will be expected to participate in field work, laboratory analysis, and regular and annual project meetings as well as lead papers stemming from this work. This position will provide the successful candidate with professional development opportunities (e.g., modeling, field work, and laboratory analysis) within the context of a highly collaborative and interdisciplinary team. In addition, this position will provide multiple opportunities to mentor undergraduate and graduate students focused on interdisciplinary careers in STEM and participate in the development of learning materials centered around the findings in this project.

The successful candidate should hold a PhD degree in soil science, hydrology, critical zone science, ecosystem ecology, or related field with a demonstrated record of quantitative research experience. The candidate should have experience with hydrologic modeling, analyzing complex datasets using scripting languages such as R, Python, or MATLAB, and have a record of publishing in peer reviewed scientific journals. Candidates with proximal or remote sensing experience applied to soils are
preferred. Candidates must have received a PhD within the past five years from an accredited college or university.

Application contents:
- One page cover letter describing the applicant’s research experiences and interests
