Sandra has a degree in Veterinary Medicine and a PhD from the University of Castilla-La Mancha. Between 2012 and 2015, she carried out her postdoctoral activity at the University of Tennessee (EEUU) in the Department of Microbiology and Genomics. In 2018, she got a diploma in Bioinformatics by the University of Pablo Olavide (Spain).

In 2016, she was granted with a Juan de La Cierva Incorporación contract in the Instituto de Investigación en Recursos Cinegéticos (IREC – CSIC, UCLM, JCCM), where she is member of the Research Group in Health and Biotechnology (SaBio). In 2019, Sandra got a research project from the Junta de Comunidades de Castilla-La Mancha (JCCM) as principal researcher, in the "Talent Retention" modality.

Her current research activity combines the microbiology with molecular, metagenomic and bioinformatic tools. This includes studies related with the host-microbiota interactions in several animal models. Her interest focuses on the study of vector-pathogen-microbiota interactions, specifically in the mechanisms of adaptation of and the role of the microbiota in vector competence, using a multidisciplinary perspective and through the integration of multiple -omic techniques.
