Arizona Laboratory for Emerging Contaminants (ALEC)

My research in the contaminant transport lab involves the study of Uranium transport through fractured rock cores. I am designing a column experiment to track the movement of Uranium as groundwater flows through fresh fractures in rock cores from Livermore, CA. In addition to rock, I will also be conducting a similar experiment with sediments from Northern Arizona, and comparing the transport properties of these porous media.

Julieann Marie Fonseca is a first-generation college graduate with a Bachelor of Science degree in Public Health emphasized in One Health. Providing services and information to a community was introduced throughout her undergraduate education as a student worker at the University of Arizona Libraries.

My research focuses on the applications of electromagnets for water disinfection and biofilm removal, real-time evaluation of soil health using an ATP/AMP detection method, and viral fate through anammox wastewater treatment.

I am working with Dr. Jon Chorover at the Central Date Palm Laboratory (Muscat, Oman) in the one Million Date Palm Plantation (MDPP) project.

I work on incorporating soil moisture modeling to improve drought monitoring techniques across the southwestern United States. Many drought monitoring techniques ignore the impacts of soil on drought, which is a crucial component of overall ecosystem health. By identifying how soil impacts drought propagation, local rangeland managers and government officials can make better decisions about how to manage Arizona's grasslands.
