I am a pediatric oncologist with a special interest in tumours in the central nervous system. 

Having earned a degree at the University of Barcelona, I obtained a specialty in Pediatrics and Specific Areas at SJD Barcelona Children's Hospital. After that, I trained in pediatric oncology at  SJD Barcelona Children's Hospital and since then I have worked as an attending oncology physician with a specialty in neuro-oncology. I am currently studying for a doctoral degree on oncology patients who need to be admitted to an intensive care unit.
