Dr. Daria Boglaienko (PhD in environmental engineering) is a chemist at Pacific Northwest National Laboratory (PNNL) supporting the Energy and Environment Directorate. She has experience in X-ray absorption spectroscopy, synthesis and characterization of bismuth-based materials and zero-valent iron for uptake and sequestration of radioactive contaminants, characterization of fission products, decontamination of steel surfaces with removable coatings, radionuclide wet chemistry and separations, data acquisition with lab-scale X-ray absorption and emission spectrometers, and chemical speciation modeling.

Prior to joining PNNL, Boglaienko conducted research on sequestration of radioactive contaminants (Tc-99) from aqueous waste streams with zero-valent iron at Florida International University, where she received her master’s and doctorate degrees and was employed at the Department of Civil and Environmental Engineering and Applied Research Center. Her research experience also includes interfacial science in relation to capture of oil spills with granular materials and agroecology with geographic information system mapping and soil characterization. Boglaienko is a certified engineer in training in environmental engineering through the National Council of Examiners for Engineering and Surveying.
