About  |  Publications | Lab Members


Dr. Camila Silva graduated from Triângulo University Center (Brazil) with a bachelor’s degree in nutrition, then received a master’s degree in immunology and parasitology from the Federal University of Uberlândia (Brazil) and a Ph.D. in biomedical research from the School of Medicine of Ribeirão Preto, University of São Paulo (Brazil). During her Ph.D. training, she spent four months as a visiting scientist at the Institute of Molecular Nutrition, Technische Universität München (Germany).

She joined the Division of Microbiology at FDA’s National Center for Toxicological Research (NCTR) as an Oak Ridge Institute for Science and Education (ORISE) postdoctoral fellow (2010-2011) to conduct research on molecular diagnosis of human coronaviruses circulating in Arkansas during the flu season. In 2014, Dr. Silva joined the Division of Biochemical Toxicology at NCTR as an ORISE postdoctoral fellow, was converted to a staff fellow in 2016, and became a research biologist in 2022. She has conducted research on the potential use of circulating micro ribonucleic acids (miRNA) as minimally invasive biomarkers of toxicity in collaboration with investigators in NCTR’s Division of Neurotoxicology and Division of Bioinformatics and Biostatistics.

Research Interests

Dr. Silva has participated in studies using animal models to assess the toxicity of products of interest to the FDA, including the food adulterants melamine and cyanuric acid and the dietary supplements nattokinase and lumbrokinase. As a response to the COVID-19 pandemic, Dr. Silva used her background in virology and molecular biology to develop a method to monitor wastewater samples for the presence of the new coronavirus SARS-CoV-2. This method is being applied for routine detection of the virus and to help surveil the extent of the COVID-19 epidemic in local communities in Arkansas. Dr. Silva plays an important role in the optimization of methods, sample preparation and processing, and data analysis to support ongoing studies in the Division of Biochemical Toxicology. She is investigating the use of miRNA and gene expression as molecular endpoints to assist in toxicity assessments and the molecular mechanisms by which compounds of interest to the FDA induce toxicity.
