Biography
After defending my PhD in 2008, focused on different aspects of the epidemiology of tuberculosis and paratuberculosis in Spain, I served as the head of the unit of neglected and emerging diseases in the VISAVET Health Surveillance Center, Spain, for two years, and then held two post-doctoral positions at the Spanish wildlife research institute (IREC) of Ciudad Real, Spain, and at the Research Institute Ramón y Cajal (IRYCIS) focusing on the epidemiology of bacterial zoonotic diseases in wildlife and humans. After this I joined the University of Minnesota in 2014, first as a research associate and then as an assistant professor, and came back to VISAVET in 2018 with a Ramon y Cajal postdoctoral contract. My research is currently focused on the application of quantitative approaches for the study of the epidemiology of infectous diseases in the human-animal-environmental interface.
I have co-authored over 100 papers in the peer-reviewed scientific literature, being first or last author in 36 of them; I have acted as PhD advisor of four students in the last 5 years, and currently act as scientific advisor of the European Laboratory for Bovine Tuberculosis, as well as a scientific reviewer for 12 indexed scientific journals.

Investigation

Research lines:
- Characterization of the emergence of foodborne pathogens subjected to surveillance and monitoring programs through quantitative epidemiology (EPIQ)
- Evaluation of the performance of diagnostic tests for diseases of importance in animal health and assessment of their application in the frame of control and surveillance programs (EPIQ)
