Professional Profile

Dr. Brianna Rivera is a toxicologist in ToxStrategies’ Health Sciences Practice, working in the Asheville, NC, office. She recently earned her Ph.D. in Toxicology from Oregon State University’s Department of Environmental and Molecular Toxicology. Her dissertation research focused on simplifying complex environmental mixtures by integrating toxicity data, using in vivo, in vitro, and in silico model systems or exposure data (i.e., consumer habits, demographics, environmental factors) to prioritize chemicals of interest. Specifically, she applied these chemical prioritization approaches to identify important combinations of consumer product-related chemicals from personal or household sampling and polycyclic aromatic hydrocarbons identified at a contaminated site. During her academic career, she completed internships in both the regulatory (USEPA Center for Public Health and Environmental Assessment) and private (consulting) sectors.

Dr. Rivera has a diverse, interdisciplinary background in exposure science and safety assessment. She has experience gathering toxicity values and conducting human health risk assessments for environmental sampling, along with a strong foundation in statistical and graphical analysis of large, multidimensional data sets using R and GraphPad. Her skills include using the software packages SWIFT-Review/Active Screener, DistillerSR, HAWC, EJ Screen, and JMP Pro. Working in the field and lab, she has constructed, deployed, and extracted passive samplers; prepared analytical standards; conducted analyses using gas chromatography–mass spectrometry (GC-MS); and studied primary lung cells (2D and 3D) and zebrafish.
