About  |  Publications | Lab Members


Dr. Camila Silva’s academic career began in Brazil, where she graduated with a Bachelor of Science in nutrition from Center University of Triângulo in 2001. She received a Master of Science in immunology and parasitology from Federal University of Uberlândia in 2006 and a Ph.D. in biomedical research from the School of Medicine of Ribeirão Preto, University of São Paulo in 2010. During her Ph.D. appointment, she spent four months as a visiting scientist at the Institute of Molecular Nutrition, Technische Universität München, Germany. She joined Dr. Marli Azevedo’s laboratory at NCTR as an ORISE postdoctoral fellow in the Division of Microbiology (2010-2011) to conduct research on molecular diagnosis of human coronaviruses circulating in Arkansas during the flu season. In 2014, Dr. Silva joined NCTR’s Division of Biochemical Toxicology as an ORISE postdoctoral fellow, under Dr. Luísa Camacho’s supervision and was converted to FDA staff fellow in 2016. She conducted research on the potential use of circulating miRNAs as minimally invasive biomarkers of toxicity within the Division of Biochemical Toxicology and in collaboration with investigators in the Division of Neurotoxicology and Division of Biostatistics and Bioinformatics. Dr. Silva has published 11 articles in peer-reviewed journals and seven book chapters.  She received an honorable mention from the Society of Toxicology’s Molecular and Systems Biology Specialty Section Postdoctoral Fellow Research Award for the presentation of the poster entitled “Serum miRNAs as biomarkers of nephrotoxicity in female and male rats fed a diet containing melamine and cyanuric acid” at the 55th Annual Meeting of the Society of Toxicology in 2016, and an award from the South Central Chapter of the Society of Toxicology 2016 Annual Fall Meeting for the presentation of “Serum miRNAs as biomarkers of nephrotoxicity in rats co-exposed to melamine and cyanuric acid.”

Research Interests

Currently, due to the COVID-19 pandemic, Dr. Silva is focused on a research project to develop a method to monitor the presence of the new coronavirus SARS-CoV-2 in local community wastewater in Arkansas using her expertise in molecular biology. This type of approach also has the potential to identify future outbreaks of COVID-19. Dr. Silva has participated in studies using animal models to assess the toxicity of products of interest to the FDA, including the dietary supplements nattokinase and lumbrokinase that are marketed to prevent blood clotting in humans due to their so-called fibrinolytic activity. 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 has interest in researching miRNA and gene expression as molecular endpoints to assist in toxicity assessments.
