I have a degree in Physics from the University of Barcelona (UB), a degree in Materials Science and Engineering from the Polytechnic University of Catalonia (UPC) and a Master in Nanoscience (UB). In 2009, I obtained my PhD in Nanoscience (UB) under the supervision of Prof. Xavier Batlle where I developed new processes for the controlled synthesis of magnetic nanoparticles. During my first postdoctoral stay at the Italian Institute of Technology (IIT) I continued to develop new nanomaterials for nanomedicine specializing in hyperthermia therapies under the supervision of Prof. T. Pellegrino and Prof. L. Manna. In 2013, I got awarded with a TecnioSpring (2014-2016) and joined the groups of Prof. D. Brougham (DCU, Dublin) and Prof. A. Cabot (IREC, Barcelona) where I started developing novel nanocrystals and assembly approaches for advanced multifunctional nanocomposites. After a short period at ICN2 under the supervision of Prof. A. Merkoçi, I was appointed as TecnioSpring+ (2017-2019) fellow at the Catalan Institute for Energy (IREC) where I settled down and started my own research group in 2019 in the framework of a young researchers national project (Proyecto Jóvenes Investigadores) from the Spanish Ministry of Science and Innovation. Finally, I could secure a Ramon y Cajal tenure track position and joined ICMAB in April 2021 where I currently develop my own research line as a member of the Nanoparticles and Nanocomposite groups.

Research interest

I am a materials scientist interested in the study of novel colloidal synthesis, and its influence in the structural properties, for multifunctional nanomaterials. In particular, I am focused in the rational design of novel nanomaterials for nanomedicine and energy applications. Currently, I am involved in several activities related with: I)-Studying large-scale and sustainable colloidal synthesis approaches for nanocrystals with precise control over morphological, physical and surface chemistry properties; II) Designing nanocrystals and nanocomposites for electrochemical water splitting; III) Developing magneto- and/or plasmonic-thermoelectric multifunctional nanocomposites for novel energy harvesting and transfer technologies.
