Position Highlights Postdoctoral Scientist Position: The Role of Soils in the Spread of Valley Fever
We are seeking a motivated and energetic postdoctoral scientist to join an interdisciplinary research team on a project designed to better understand the role of soil composition and seasonal soil dynamics in the spread of fungal spores of Coccidioides posadasii - the infectious agent of Valley Fever. The research team comprises soil scientists, atmospheric scientists, microbiologists, and medical disease specialists from the University of Arizona, Arizona State University, and Northern Arizona University. This collaborative team will be combining soils investigations with atmospheric particulate matter sampling, detection of Coccidioides spores in air sampled at positive soil locations, genome analysis from environmental and clinical samples, and geospatial modeling/visualization of diverse Valley Fever data. The goal is to better resolve "hot spots" and "hot moments" of Valley Fever disease spread in Arizona landscapes.

Outstanding UA benefits include health, dental, vision, and life insurance; paid vacation, sick leave, and holidays; UA/ASU/NAU tuition reduction for the employee and qualified family members; access to UA recreation and cultural activities; and more!

The University of Arizona has been recognized for our innovative work-life programs. For more information about working at the University of Arizona and relocations services, please .

Duties & Responsibilities

The postdoctoral scientist will hold primary responsibility for identifying soil characteristics most frequently associated with high prevalence of Cocci spores and determining the soil and ambient atmospheric conditions that promote the aerosolized suspension and off-site transport of Cocci spores from those locations. We seek to answer the question: What physico-chemical soil characteristics and conditions promote Cocci spore release? The data generated will inform a geospatial risk model.

This will involve:

  • Establishing and maintaining instrumented soil sensor networks for collection of continuous data streams at selected field sites (soil moisture and temperature probes, weather stations, dataloggers);
  • Excavating soil profiles for depth-dependent sampling for subsequent laboratory analyses;
  • Analyzing soil samples for biogeochemical composition (organic matter content and chemistry, mineral and metals composition, nutrient and ion concentrations, particle size distributions);
  • Conducting additional investigations and analyses depending on the postdoctoral scientists interests and expertise.
  • The postdoc will join the research group of Prof. Jon Chorover in the Department of Environmental Science at the University of Arizona, which is focusing on the soils component of this larger study.
Minimum Qualifications
  • Ph.D. in Soil Science, Environmental Science, Geosciences, or a related field.
  • Evidence of capacity to work well in an interdisciplinary team context.
  • Experience that demonstrates understanding of, and interest in, the role of soils in environmental health and quality
  • Ability to drive according to the University .
