Deputy Director — Division of Biochemical Toxicology
Luísa Camacho, Ph.D.
Dr. Luísa Camacho is the Deputy Director of the Division of Biochemical Toxicology at FDA’s National Center for Toxicological Research (NCTR). She received a bachelor’s degree in applied plant biology from the Faculty of Sciences at the University of Lisbon, Portugal and a Ph.D. in cell biology from the University of Lisbon. She was a research associate at the School of Biological and Biomedical Sciences at the University of Durham, UK and was an academic visitor at the Department of Plant Sciences at the University of Oxford, UK. Dr. Camacho joined FDA’s National Center for Toxicological Research (NCTR) in the Division of Biochemical Toxicology as a postdoctoral fellow in 2007, converted to an FDA staff fellow in 2009, was hired as a research biologist in 2021, and appointed deputy director in 2022. Dr. Camacho has published over 30 peer-reviewed research articles and four book chapters. She has served as an expert member in multiple working groups, including for the International Agency for Research on Cancer. Dr. Camacho is the section editor for “Pharmacology, Toxicology, Pharmaceutical Sciences” of the journal Data in Brief and the Editor-in-Chief for the Journal of Environmental Science and Health, Part C – Toxicology and Carcinogenesis.
Dr. Camacho’s research focuses on the conduct of animal studies to assess the pharmacokinetics and toxicity of products of interest to the FDA. A particular emphasis of her research has been on toxicological studies that include exposures during the perinatal period of life. She complements toxicity assessments with molecular endpoints to characterize molecular mechanisms for compounds of interest and to identify potential novel biomarkers of toxicity. These studies are conducted in close collaboration with colleagues from FDA product centers, the National Institutes of Health, and NCTR. Dr. Camacho served as a scientific coordinator of the Consortium Linking Academic and Regulatory Insights on Bisphenol A Toxicity (CLARITY-BPA), a collaborative research program between the FDA, the National Institute of Environmental Health Sciences, and university-based researchers that provided data for the safety assessment of bisphenol A, an indirect food additive. Other studies included the comparison of the dose-response and temporal dynamics of traditional (blood urea nitrogen and serum creatinine) and novel (serum micro ribonucleic acids) biomarkers of nephrotoxicity upon a combined exposure to melamine and cyanuric acid, and the evaluation of the toxicity of the plasticizer di(2-ethylhexyl)phthalate (DEHP) and of the dietary supplements nattokinase and lumbrokinase. Current research efforts include the characterization of the pharmacokinetics of cannabidiol in a rat model upon oral and dermal exposures, and the evaluation of the performance of a 3D bioprinted human skin equivalent model for in vitro permeation testing.
