In 2012 she made a training stay at the Department of Genetics Biochemistry of the Mayo Clinic in Rochester, MN, USA, to learn about new analytical
applications of neonatal screening that she is currently performing (second level tests and post-analytical computational tools). In recent years, she has tried to combine her care work with clinical research. The fields in which she is especially interested are: the introduction of new markers in neonatal screening by tandem mass spectrometry, the quality assurance of the program, the evaluation of new technologies applied to newborn screening and the diagnostic approach to hereditary metabolic diseases. She has been principal investigator in several competitive grants and author of more than twenty publications in JCR-indexed journals. She belongs to the cross-sectional area of IBIMA-RARE.
