Sandra Callejas Martos

Sandra Callejas Martos is a Chemist with a master’s degree in Analytical Chemistry. Currently enrolled in a Ph.D. at the Institute of Environmental Assessment and Water Research at the Spanish National Research Council (IDAEA-CSIC - Barcelona, Spain). Her Ph.D. is focused on developing various sampling methods to estimate exposure routes, such as inhalation (using breathing manikin) and dermal contact (using silicone wristbands), besides studying the total exposure to chemical additives with the analysis of metabolites in urine. She works with methods based on liquid chromatography coupled to high-resolution mass spectrometry such as Q-Exactive Orbitrap, QqQ, and Hybrid Q-ToF.
