Dr. Royer specializes in the biodegradation and fate of perfluorinated alkyl chemicals (PFCs), hormones, pharmaceuticals and personal care products (PPCPs), and abiotic and biotic transformation of PCBs in contaminated soil. She has expertise in the area of organic chemistry, primarily in analyzing environmental fate and behavior, with additional background in environmental chemistry, analytical chemistry, and soil microbiology. During her doctoral work, she designed and implemented experimental procedures to test the amenability of fluorotelomer-based monomers to biodegradation in aerobic soils. Her analytical expertise includes fungal culturing techniques, gas chromatography with detection by electron capture, flame ionization, and mass spectroscopy (GC-ECD/FID/MS), liquid chromatography - mass spectrometry (LC/MS), and nuclear magnetic resonance (NMR) analyses.
Before joining Exponent, Dr. Royer attended Purdue University, serving as a research assistant in the Department of Agronomy—Crop, Soil and Environmental Sciences. In addition to her graduate work, she taught courses in soil physics for undergraduate and graduate students, as well as a soil fertility course. Dr. Royer also has expertise in communicating complex scientific concepts to non-scientific audiences in remote, rural, and urban communities.
