Marta graduated in Pharmacy (MPharm) from the Complutense University of Madrid in 2016, during which she also studied at the University of California San Diego (UCSD). During this time, she also collaborated in a neuropharmacology project at The Scripps Research Institute. After graduating with high interest in the public health field, she volunteered as a pharmacist in a health promotion campaign in rural areas of Ecuador. Upon returning, she worked as scientific advisor trainee at GlaxoSmithKline in the Vaccines Medical Department, which sparked her interest in vaccines and vaccine policy. She completed an MSc in Public Health from the London School of Hygiene and Tropical Medicine in 2018, writing her thesis on the impact of quasi-mandatory vaccine policies in vaccine uptake in Australia. She has worked in epidemiology since then, starting as a public health intelligence analyst in the joint Department of Public Health of two inner London boroughs (Camden and Islington). She is currently a surveillance scientist in the Immunisations and Vaccine Preventable Diseases Division at the UK Health Security Agency, mainly on Invasive Pneumococcal Disease, Haemophilus Influenzae and Rotavirus.
