Research Interests
My research investigates the behavior of toxic metals such as arsenic (As), chromium (Cr), and lead (Pb), as well as essential nutrients like phosphorus (P), nitrogen (N), and sulfur (S) in soils. I explore how these elements are bound to soil particles under varying environmental and experimental conditions, including changes in pH, temperature, hydration state, microbial presence, and duration of exposure. Additionally, my work examines how different climatic factors, such as temperature fluctuations, moisture levels, and extreme weather events, influence the interactions and transformations of these metals and nutrients within the soil matrix.
To achieve this, I utilize advanced analytical techniques, including bright light sources at synchrotron facilities, to determine the molecular forms (species) of these metals and nutrients in soils. This molecular-level understanding is crucial for accurately predicting how these contaminants might leach into groundwater or surface water, which in turn affects their toxicity and bioavailability to plants, animals, and humans. By understanding these processes, my research aims to contribute to the development of effective strategies for managing soil contamination and safeguarding environmental and public health.

Facilities/Resources
Izaditame Lab: PI Izaditame’s laboratory, Environmental Soil Biogeochemistry Laboratory (ESB), is an individual space within the ECSW of UT Dallas that includes approximately 800 sq ft of laboratory space. The research facilities of the Environmental Geochemistry Laboratory include dedicated space for sample preparation and analysis. This includes fume hoods, refrigerators, -80 C freezers, research grade quality water supply (type-1 water system), Orion Versa Star Pro pH/EH/T benchtop meter, precision balances, analytical balances, digital rotors, digital rockers and vortex mixers, advanced shakers, magnetic stirrer hotplates, and Multifuge X4FR Pro high speed refrigerated centrifuge and rotors. In addition, the Departmental research facilities at the Department of Sustainable Earth Systems Sciences include digital imaging petrographic microscopes, rock preparation and mineral separation facilities. Separate research facilities for computing, hydrology, geophysics, geochemistry, educational filmmaking, microimaging/microanalysis, and paleomagnetism/rock magnetism. The Department also possesses four research vehicles for fieldwork (mileage charges). Moreover, the UTD School of Natural Science and Mathematics is fully equipped with a series of analytical instruments which offers most soil analysis commonly performed including trace element analysis, stable isotope measurements, NMR and XRD analysis (for a complete list and more details please refer to the website linked Here).
