In 2004, she moved to Barcelona to develop her career as a researcher and teacher at the Polytechnic University of Catalonia, where she is a researcher in the Non-Linear Dynamics, Non-Linear Optics and Lasers (DNOLL) group. She has been distinguished twice with the ICREA Academia award in 2009 and 2015, in recognition of excellence in research.
As a DNOLL group researcher, she has participated in the development of a simpler methodology than those previously applied for the identification of an ordered structure in a chaotic system. Masoller has contributed to developing the interest of the scientific community to implement a non-linear methodology in the analysis of complex climatic phenomena, such as El Niño. Between 2012 and 2015 she directed a European project (LINC project, Learning About Interacting Network in Climate) to train 15 young researchers in the study of complex systems applied to the analysis and prediction of climate phenomena. Based on her experience with laser semiconductors, the researcher argues that complex phenomena such as weather can be studied with methodologies similar to those applied to the study of complex networks, such as neural networks, the Internet and the economic system.
She has participated as the author of more than a hundred publications in relevant scientific journals in her area and her work has been cited in other academic papers more than 4500 times.
